Pulp necrosis and root canal treatment

Root canal therapy is appropriate disinfection by removing necrotic material within the root canal, root canal filling to remove the negative stimulus of the contents of the root canal apical surrounding tissue and prevent the occurrence of periapical lesions or promote periapical lesions heal a method of treatment. Pulp necrosis and chronic pulpitis, pulp and periodontal syndrome and systemic disease not suitable extraction and in need of treatment or suspension of retained teeth are indications of root canal therapy.

There are two ways in the implementation of the root canal therapy. Double or multiple method: first cavity preparation of opening the chamber to flush the canal dental instruments and removal of necrosis, gangrene of the pulp, expand the root canal, and again rinse clean root canal, enclosed disinfection drugs after sucking about 2 to 7 days; If there is no referral The obvious reaction, namely removal of the seal material, root canal filling; if obvious reaction can be re-enclosed disinfection drugs, the next root canal filling. The first method: The system open pulps, rinse, expand the root canal, root canal filling immediately, once completed.

In the treatment of much preservation of teeth, long-term efficacy of root canal therapy is the basis of post crown restoration. Therefore, the residual crown Four major factors that cause pulpitis and root tooth, root canal therapy is the only treatment of choice.

The process of pulp necrosis, root canal therapy, doctors completely remove the infected pulp and infected dentin and toxic decomposition products, root canal treatment-specific instruments by closely filling the root canal, isolated the bacteria into the root canal re-infection, to prevent periapical lesions or promote the healing of periapical disease.

Which tooth inflammation do root canal treatment?

Many people root inflammation, pain tough battle, go to the hospital, the results need to do root canal treatment. Cosmetic dental network doctor said, teeth, bad often with tooth extraction to solve the problem, there is now a root canal treatment technology, so that originally pulled out teeth retained after repaired to continue to use.

The root canal treatment is a course of treatment for the teeth, dental pulp and periapical lesion. Root canal therapy is appropriate disinfection by removing necrotic material within the root canal, root canal filling to remove the negative stimulus of the contents of the root canal apical surrounding tissue and prevent the occurrence of periapical lesions or promote periapical lesions heal a method of treatment.

A. Apical inflammation of root canal therapy: pulp infection by the dental instruments bacteria, the bacteria through the apical foramen invade alveolar bone, causing tissue inflammation around the root apex, root canal treatment to remove the infected dental pulp, root inflammation will subside.

Two. Pulpitis root canal treatment: dental pulp by bacterial infection, inflammation, dental pulp in the pulp chamber sealed are generally not subject to bacterial infection, when the teeth due to caries (cavities) have holes, and when the hole was too deep, external bacteria will be How to tell the beauty crown is good or bad invasive infection of the pulp to the pulp cavity. The pulpitis root canal treatment can be definitive treatment.

Is more complicated root canal therapy, the technology for doctors, hospitals hardware facilities requirements are relatively high. Thus, patients with toothache if you need root canal treatment, be sure to choose a regular hospital in order to avoid inadequate treatment, resulting in infection continue to deteriorate.

Cast porcelain tooth life factors

Cosmetic dental network cosmetic dental experts: cast porcelain dental all-ceramic dental is used in the production process of all-ceramic porcelain teeth, does not contain any metal components. The repair effect and the price are more expensive. Of life cast porcelain teeth are more concerned about. But dental experts said the life of the cast porcelain teeth by many factors. What are the factors related to the life of cast porcelain teeth?

The life of the cast porcelain teeth depends primarily on the following aspects:

1. The doctors and technicians, technology related to the life of cast porcelain teeth. Seriously regulate tooth preparation doctors and technicians, best production is the basis for a highly skilled medical technique to produce high-quality cast porcelain teeth.

2. The design is reasonable, about the life of the dental instruments cast porcelain teeth. Cast porcelain tooth design is unreasonable; it is possible to dentures fractured porcelain breakage real teeth loose, and phenomena such as excessive force, which affects the life of cast porcelain teeth.

3. The patient's usage relates to the life of the cast porcelain teeth. Cast porcelain teeth to eat the cake and gnawing ribs every day is definitely not the same. If you used to open bottles, cast porcelain teeth are not long than real teeth. If you do not Malocclusion hazards brush your teeth, lightly chew on things, and will greatly reduce its service life.

Life of cast porcelain teeth by the above factors, but according to the study, well-made cast porcelain teeth, with the correct way to use and good maintenance of its life can be maintained for 10-20 years or even longer.

How to make more solid fillings?

Each tooth has a topic of concern by the defect friends. So, how fillings can make teeth more robust it? Dental Hospital of experts, fillings, and the preparation of a good for filling or treatment of cavities whole shape is the key to treatment of dental caries in dental.

In general you want to prepare the box-shaped hole-shaped, double-sided hole to form a ladder; remove unnecessary-based glaze. Have a certain retention form. The use of sidewalls, undercuts, dovetail, ladder to prepare the solid shape. Followed across the wet, disinfected and dried. Clear the cave into the bacteria due to caries and operation of prepared rubber or cotton balls, gauze, with the aspirator allows the surgical area to prevent saliva contamination, which will dental instruments help dry cave, so to make the filling material to fully contact with tooth structure and improve the quality of the filling. Finally select the appropriate bottom and Filling Materials for the engraving of the tooth surface shape, adjust the occlusion. In this way, the complete a quality plombage.

Thus, if the caries organization failed to remove clean; if the preparation of the hole deep enough, or the bottom is too thick, so that the backfill is too thin; if the occlusal area of the hole or solid form improper preparation, like the occlusal surface of the adjacent teeth no dovetail or dovetail too narrow shallow hole, proximal trapezoid axis myeloid line angle too sharp, the hole is larger than the bottom of the cave a minor box-shaped; disproportionate mixing of filling materials inside the cave, such as blood or saliva moisture contact materials, the bonding surface is not dry, can affect the filling quality. Therefore, to overcome the above aspects of the adverse factors, the completion of the filling procedure of a high quality, will be able to fill teeth more firmly. Hospital Dental experts have warned that, although the fillings is a minor, but it also has a very high technical requirements, not to take cheap, filling in some non-standard small clinic to regular hospital quality assurance treatment.

Types of invisible orthodontic

More and more people selected in orthodontics when invisible orthodontics, this is because the invisible orthodontics with beautiful, convenient, practical advantages. Invisible orthodontics is a new 3D stereoscopic computer technology, tailor-made a series of nearly undetectable transparent denture to complete the corrective treatment.

At present, invisible orthodontic without brackets invisible orthodontics, lingual orthodontics invisible, ceramic brackets invisible orthodontics. Invisible orthodontic bracket appliance without steel Situo slot, transparent and thin, others almost imperceptible; through the process of three-dimensional computer image technology to simulate tooth movement, and dental instruments so made the appliance put on the teeth accurately to the design good move; appliance fixed to the teeth, the patient can pick their own wear, easy to clean teeth, will not affect the work and study.

Lingual invisible orthodontic appliance placed in the homes side appliance mostly foreign imports polymer materials made ​​of, so the higher cost; the first month of the correction may have an impact on the pronunciation, after strengthening exercises can basic to Orthodontics to pay attention to things improve and adapt the course of 2-3 months longer than the orthodontic process.

Invisible orthodontic ceramic brackets, the bracket using the high transparency of the ceramic bracket invisible; lined with metal grooves, strong brackets, and contribute to the wire to slide freely, to improve the therapeutic effect; specially designed edge bevel and wingspan, more comfortable to wear, traction; the bottom of the central set of stress concentration ditch, convenient and easy bracket removal.

Do not ignore the oral health of primary and secondary

A child is in the milk and permanent teeth during the replacement of the maxilla and dental arch development growing oral health is directly related to the establishment of permanent teeth together, which is related to facial morphology, masticatory function, teeth alignment and other aspects.

High school students both in the period of susceptibility to caries, but also in the dental caries inflammation peak incidence of inflammatory swelling mainly due to local irritation of the plaque and tartar, dental caries prevention and the elimination of plaque and calculus, to maintain oral health of teeth tissues is important for health.

Primary and secondary school students most of the time spent in school, especially secondary school students, learning tension, often easy to neglect of dental instruments oral hygiene and health. And schools often neglect oral health education, which is the weak link of oral health. Which parents need to understand the knowledge, guidance and supervision and protect teeth, do not penny wise and pound foolish, cause irreparable damage to the child.

This period, parents must educate their children to foster awareness of oral health, teach them the correct method of brushing, fluoride toothpaste, so that they develop good habits of morning and evening brushing, mouthwash after meals.

Diet, rational nutrition and encourage children to eat coarse food  and fruits and vegetables, eat a particularly fine food and confectionery. If tartar, plaque should be Children have more dental causes and solutions cleared as soon as possible. The best new eruption of permanent teeth in a timely manner to do the pit and fissure sealant. If caries should be treated early.

What are the dangers of tooth decay?

Hazard Analysis of tooth decay: tooth decay once formed, should be timely to find a dentist treatment, otherwise, slowly, the cavities will be increasing, tooth decay slowly getting serious, we both eat cold, heat, sour, sweet food, the teeth will be severe pain, has caused us to eat sleep well, live well and learn. If tooth decay does not receive timely treatment, may result in tooth loss, tooth loss can affect a range of issues of mastication, pronunciation, and face beautiful. And dental instruments medicine tells us that dental problems can even compromise the body, causing gastritis, arthritis, skin infection such as cystitis. Therefore, we must take good care of teeth.

The hazards of tooth decay - cavities Why make we feel hurt it?

Cavities inside the cave, the bacteria caused by pulp inflammation, stimulate the pulp nerves, so we will feel the pain.

Hazards of tooth decay - why children are likely to have tooth decay?

For children and school students, due to the low degree of calcification of deciduous and depth of the fissure of a new eruption of permanent teeth, a higher prevalence of dental caries, coupled with a sweet tooth, and who can not grasp the correct oral health knowledge, so it is susceptible to tooth decay. Primary and secondary students are at an important period of oral health: eruption from the age of six permanent teeth continue to the deciduous turn off, the formation of mixed primary and permanent dentition stage, until about 12 years old, until the permanent teeth eruption all, this is the jaw and Denture process Detailed teeth of children bow development of an important period of growth, this period is also caries, gingivitis during the peak period of the disease. Children must take good care of teeth, to learn proper oral health knowledge.

What is sandblasting scaling principle?

Blasting scaling principle is to use a special blasting tooth powder (sodium bicarbonate powder as the main ingredient), by sandblasting phone head sprayed into the tooth surface to remove plaque and pigment. This method is especially applicable to the clean-up of plaque in the ultrasonic scaler is not easy to reach tooth gap and pigmentation spots, for the clean-up efficiency of the tooth surface pigment is also much higher than the ultrasonic scaler.

The blasting scaling principle the most important function of polishing the tooth surface: the end of the ultrasonic scaler or hand cleaning teeth, the patient's tongue usually feel the tooth surface rough; blasting scaling the tooth surface rough feeling . The blasting scaling cans not just polishing the outside of the teeth, and teeth between dental instruments the tooth surfaces can be polished. Tooth surface after polishing is not easy to attach to the plaque and pigment.

Blasting scaling principles of scientific scaling method of brushing food debris deposited in the teeth, horizontal brush their teeth, the bristles entered between his teeth how can to remove food residues in the teeth? The correct method of brushing should be along the Children the proper dental care vertical brush teeth France, this brush method can bristles out into the teeth, so clear tooth effect. Specific brush method is roughly: the toothbrush on the teeth and gums at the junction of the bristles and teeth to a 45 degree angle, then rotate the brush along the teeth, brush, brush on the teeth from top to bottom brush, brush the lower teeth from the bottom up, brush.

The beauty crown straightening teeth?

Dental anomalies can be said that everywhere, people have been surprised, dental anomalies gives the appearance of serious and even cause psychological shadow, a lot of beauty to endless pain, surely we are not now beauty crown a stranger. So, the beauty crown straightening teeth? Deformed teeth correction, beauty crown is very popular, the effect is very good, the patients of all ages after the popular experience.

The beauty crown is a currently popular in Europe and the United States, Japan and Korea, new cosmetic teeth. Beauty crown correction of deformity teeth using new technology, digital positioning technology, The WIND painless technology, international advanced dental technology and ideas, with the US-tooth non-extraction, no pain, time is short, strong teeth, the teeth do not appear after many years black line, so as to achieve lasting protection US-tooth effect. The beauty crown 3D digital positioning technology, combined with the face, color design of the U.S. dental program and dental instruments corrected teeth, beautiful.

Beauty crown for the rabbit teeth, my teeth, eye teeth, mouse teeth (small teeth), to package the day, the front teeth crowded, sparse anterior teeth, dentition, dental defects, porcelain failed, missed the correction of adults of the golden period and severe tetracycline, etc., have very good results. These dental anomalies, beauty crown can easily get not only better, and requires only seven days, you can easily have white even teeth. There are vague please yake_net_cn teeth dot com QQ Group 1097-836 · 61 dental exchange of understanding.

These are the beauty crown straightening teeth of the How to get children to eat healthy your teeth introduction, you understand? A dental expert, the beauty crown correction is a professional adult orthodontic method, the characteristics of the design of adult teeth, does not rebound, can not only guarantee the appearance of the face, and ordered to restore the teeth. However, it is important to note that the beauty crown-year-old ah well, but to a regular cosmetic surgery hospitals will ensure that the effect.

How do children's oral health?

Children's oral health should babies start. Babies from 4 months, you can use a clean gauze wrapped around your fingers gently massage the gums, be careful not to let your baby develop bad habits, his mouth bottle to bed or prolonged biting bottle feeding of cotton dipped in boiling water stick residual milk for the baby clean mouth block to prevent the sugar in milk acidification in the mouth. The age of two parents should be mentoring and training proper brushing habits, maintaining a healthy and balanced diet. The new eruption of primary teeth for pit and fissure, and regular visits to the hospital for an examination of the oral specialist.

Why deciduous teeth susceptible to caries? Children's tooth of caries incidence is particularly high, according to statistics can be as high as 70 to 80 percent, mainly due to:

1. Lower degree of calcification of the teeth, poor acid resistance.

2. Children's eating habits and eat sweets and dental instruments snacks, and soft, easy to adhere to the teeth after eating, reproduction conditions for the growth of cariogenic bacteria.

3. Children sleep a long time, the saliva secretion, oral self-cleaning effect, but also conducive to the growth of cariogenic bacteria.

4. Physiological clearance of deciduous existence, easy inlays food.

5 Children can not be good to brush your teeth, the tooth surface residues.

Deciduous teeth anyway, want to change, where he also does not matter, right? Not treated the teeth, and will first affect chewing function, deciduous and permanent teeth are the same as an important role if there is no deciduous teeth to chew food to increase the affordability of child stomach, nutrition absorption, so that the child's development be affected. And then lead to premature tooth loss or retention is not pulled out in a timely manner will cause unnecessary malocclusion; even affect the normal development of the facial bones. The child deciduous teeth eruption law? The majority of Beauty crown to help you solve the genetic pigment teeth babies born before and after 6 months began the eruption of the first one deciduous-year-old semi-homogeneous, the eruption of the process follow the eruption of the mandibular deciduous first and then the eruption of the maxillary deciduous law. Under normal circumstances, about the same name as tooth eruption time is near, under the same name teeth, while the lower teeth eruption is earlier. Although baby teeth eruption time there are certain rules, but each baby's development, and some may be earlier eruption, and some may be later, but is still not an age of eruption of primary teeth, they should go to the hospital to examine the reasons.

The bridge design and production of the posterior teeth bonding

1. after dental bonding bridge retainer design

The connection angle of the missing gap side of the cheek side of the line angle and far from the center line of the buccal to the preparation of the adjacent ditch. A high degree of lack of gap proximal edge of the Long Line should not be less than 3mm, whether side should be cut grinding of the adjacent tooth tissue, in order to guarantee the strength of the proximal connection body, the occlusal surface of the tongue side should cover 2/3 of the lingual cusp.

2. Production methods

Abutment preparation: nearly missing teeth side of the adjacent surfaces, the tongue and adjacent buccal axis surface corner suddenly reduced to the gingival 1 ~ 2mm, adhesive surface co-gingival height of minimum 3mm proximal surface of the two abutment teeth nearly missing teeth gap side of the Preparation of co-care nest, and take advantage of the occlusal surface dental instruments occlusal District. Base occlusal gingival direction should be made ​​common seated Road.

Production of metal bridge: Preparation of an impression, filling anhydrite model, the production of the overall stent wax type, embedding, casting. Metal stents have good resistance retention (metal flange thickness of about 0.5mm), the case does not affect the bite and beautiful, to maximize the tongue flap (solid planes), cheek sudden Hop surface care. Gingival flap edge should leave the gingival margin of 1mm, the edge into a blade-shaped. Bicuspid bridge cheek surface can be used porcelain or composite resin (should retention device) making the need for aesthetic,

Try them: bonded bridge trying on metal stents with the fit of the tooth, bridge abutment surface tight gums, multi-directional pressure does not move, do not shake and What are the factors that affect the price of whitening not dislocation, early point of contact. Light cleansing covered with plastic sheets by the polished, sandblasted and coated with coupling agent of the bonding surface or electrolytic treatment.

Bonding: the bonding surface of the abutment teeth etching to complete the adhesion of composite resin bonding.

The three major reason for the high price of dental implants

Dental implant because of its good effects of dental restorations of choice for many patients with tooth loss do dental restorations, dental implants are more and more people recognize and accept the price of dental implants has also become an issue of common concern. Believe that going to the hospital to understand the dental implant people know that the price of dental implants compared to the high side, many people wanted to know, dental implant why so high?

1. Dental implant than the other way your denture reason is that the implant process is complex, but extremely precise, world famous cropping systems, implants and a variety of accessories, which can meet different design of the repair, the cost of fees. Dental instruments price is also expensive.

2. The dental implant is completed by the three co-operation of doctors and planting technicians planting of special planting training surgeons, implant restoration, human input. The costs are relatively high.

3. Dental Implant Denture in the production process some of the unique needs of the more expensive the repair material. Dental implant prices will be high.

I believe the introduction of the above, we can understand the high price of dental implants, the saying goes, good value for money, we can not because the job of their prohibitive, dental implant prices dental implant prices are more expensive, but the dental implant than the average of the teeth strong, good repair teeth, of course, before doing the dental implant, the first formal hospital to check whether they are suitable to do the dental implant.

Tooth decay is the correction or removal of a good?

1. Retention of primary molars failed to disconnect, the eruption of the canine blocked, leaving the canine eruption of the labial dislocation formation of tooth decay.

2. Premature loss of deciduous molars due to caries and other reasons, the permanent molars forward displacement, occupy the location of the bicuspid eruption of the canine dislocation grow formation of tooth decay.

3. Early maxillary premolars than canines eruption, the eruption of the premolars, the canine position occupied, resulting after the eruption of the canines pushed to the formation of tooth decay in a location other than the arch.

4. The underdevelopment of the maxilla, resulting in a lack of the position occupied when the teeth in order, so that the eruption of canines dislocation, the formation of cavities.

Tooth decay, disease resistance tenacious and difficult of decayed teeth in the old birthday ". Once we have the lack of tooth decay, mouth and dental instruments nose looked down riding, dull expression, giving to premature aging and flat deflated feeling. Therefore, even if the formation of cavities must not be pulled out.

Tooth decay affects the appearance of a major problem, and also more common in our daily lives, many people how "tooth decay correction?" Are very concerned about how correction for the decay of beauty technology is already is relatively developed, to effective solution to the this problem can help us,

Used in orthodontic treatment is relatively cumbersome, but better able to preserve the child's oral function, such as "tooth decay behind the teeth extracted or grinding small cavities push or pull to the normal position than the removal of tooth decay effect.”

Tooth decay how the correction is more important, the activities and appearance of tooth decay can affect the lip, and some people will unplug it. Pulled out tooth decay, on the face altercation with collapse, deepened nasolabial fold and facial fullness decreased, showing the Choose porcelain dental materials should be targeted old state, thus affecting the whole face of America. Therefore, the prudent attitude to pull the tooth decays. In order to maintain the fullness of the face, can be used during orthodontic treatment, removal of tooth decay behind the teeth, or to wear small, and then decay push or pull to the normal position. Corrective surgery methods this decay to take 2-6 months longer than the removal of tooth decay effect.

How effective the prevention of acute pulpitis

Acute pulpitis, acute dental pulp tissue inflammation, the source of infection is mainly from the deep medullary pulpitis infection can cause apical infection through the apical foramen, the main clinical features of severe pain, general pain medications little effect , the latter can develop the pulpitis gangrene, treatment of opening the chamber and medication for pain.

To effectively prevent pulpitis should do the following:

Pulpitis most of the developed by dental caries deep into dentin, the bacteria through the dentin tubule, or caused by gingival whole penetrating into the medullary cavity. The most prominent symptoms of pulpitis pain, and severe pain. A lot of trouble to the people's daily lives and should therefore be actively preventing the occurrence of the disease.

1. Exercise, and rest, infirmity, Imperial evil out.

2. On a regular basis to remove the stones of the tooth neck tooth neck to keep clean, smooth, the food residue is not easy to re-attach. Painted with iodine glycerin, and teeth which cause anti-inflammatory role of convergence, reduce purulent  discharge, reduce the gingival pocket.

3. Using a reasonable method of brushing can reduce plaque and tartar, the correct method of brushing: the brush along the teeth of the direction on the tooth brush down dental instruments on the lower teeth brush from the bottom up, outside of the inside of the root teeth and chewing The face brush.

4. The prevention of acute pulpitis include maintaining good oral hygiene, morning and evening brushing, mouthwash after meals is an important part of, oral health can reduce the accumulation of plaque and bacteria breeding.

Teeth whitening technology

Ultrasonic Scaler: exogenous yellow teeth. Can remove the oppression of the lumps of gum tartar, prevention and treatment of periodontal disease, but also remove the tooth surface staining. It is noteworthy that, two ultrasonic scaler shortest clearance time for three months or six months, to draw the teeth after cleaning teeth leaving very shallow scratches, must go through a period of time by the calcium in the saliva remineralization to recover.

For bleaching of tetracycline. It can release the new oxygen to the tooth surface color bleaching, which itself has toxic side effects. However, this bleaching only on the surface of the teeth work, different period of time, teeth will restore its original color.

Coverage mask technology: for tetracycline and dental fluorosis, the method is first the tooth surface with a weak acid corrosion, so that the tooth surface with small uneven surface, and then coated with photosensitive resin to the tooth surface coloring Results solid. Natural and dental instruments realistic, and strong and shiny. But a long time will discoloration aging (up to last for three years), need to re-refundable repair.

Porcelain crown tooth: inactivation will need to whiten teeth and taper ground, wear the crown, the teeth become white and beautiful, and wearable, durable does not fade.

Experts said domestic tooth whitening market demand, but we do not recommend the consumer tooth whitening, for domestic consumers, the protection of dental health is the most important, but so far, the market not an absolute to meet consumer demand for teeth whitening products. The anonymity of experts: Patients’ need a start of Camry oral teeth bleaching, however, this service has repeatedly caused the patient's dissatisfaction. The reason is that teeth bleaching effect is difficult to meet consumers' expectations, many consumers want teeth bleaching their teeth as the teeth of the star, white crystal, in fact, it is very unrealistic, unless porcelain teeth otherwise there are no less significant products of the whitening effect.

The type of dental implant

Experts said that the implant is implanted into that part of the alveolar bone, you can image it as a tooth root implant is very important in the entire dental implant process, the implant directly determine planting the quality of the teeth. At present, clinical implant?

Screw Implants. Having a conical and cylindrical two cylindrical more commonly used. Its material is the most common is the basis of the structure of pure titanium or titanium alloy surface treatment spraying bio-ceramics, bio-oxidation treatment, and bone morphogenetic protein. The surface structure of different forms of threaded holes or grooves, increasing the contact area with the dental instruments bone or to prevent the reverse rotation of the implant out.

The leafy implant. The leafy implant is mainly used for the cultivation of the posterior teeth loss. Missing teeth and parts of the number of missing teeth, and local alveolar bone shape design into a variety of implants; generally made ​​of pure titanium, can also be some type or two-stage two. Mainly applied to the blade-like alveolar or alveolar bone height less than. The main advantage Affect the cultivation of the five factors of dental healing of the leafy implant implantation less destruction of bone and bone contact area, the leaves thin, thick buccal and lingual side of the supporting bone, good stability after implantation for special parts with the need to design flexibility.

There is a hollow round implants. Relatively less clinical. Experts said that the choice of dental implant, the implant must be very careful to understand the characteristic of each type of implant to choose their own implants is fundamental.

What is the metal dental implant material?

Dental implant repair teeth, many patients consultant dental implant materials exactly what planting materials wife own teeth. In this regard, we are here mainly to introduce the metal dental implant material. Dental implant materials can be divided into a total of three kinds of carbon materials, metals and ceramics classes.

Metal under the premise to meet the basic biocompatibility and outstanding mechanical performance advantages, resulting in application as early as, and is still widely used in a dental implant material. Titanium and titanium alloy with good biological performance and the ideal mechanical properties has become the most widely favored a metal.

Chemical properties, titanium is an active element, a meager layer of oxide film can be formed in the surface exposed to the air the moment, this layer of the oxide film inert high degree, and can effectively prevent further oxidation and corrosion to dental instruments ensure a good biocompatibility of titanium.

In terms of mechanical strength, titanium as good dental implant materials, their low density, high mechanical strength, modulus of elasticity compared with other medical metal closer to the bone tissue, which makes titanium has better biomechanical compatibility. Also, such a dental implant material also has good machining properties. Therefore more than 90% of the cultivation Understand the dental materials and characteristics of products based on titanium or titanium alloy material.

Other commonly used metal of 316L stainless steel, cast cobalt chromium molybdenum alloy, etc., but because of biological and mechanical properties of the defects have gradually been replaced by titanium. In addition, there are some rare metals such as tantalum, zirconium and so can be used as dental implant materials, but also has good biocompatibility, but the price is expensive and therefore rarely used.

An important indicator of tooth whitening

Teeth transparent sense of how it formed? It is a unique texture to the surface of the tooth enamel are given teeth, the impact of transparent enamel, mainly enamel water content, water content, the higher the teeth, the more exquisitely carved. BEYOND whitening technology, using high-intensity blue wavelength range of 480-520 nm, throughout the decolorizing process is completed at low temperatures, and completely avoids the problem of dehydration. After the teeth bleaching, teeth the more it is crystal clear and smooth.

In addition, the gloss index. Like the jade industry, which said, enamel density of impact to the tooth surface reflective capacity, the gloss of the teeth. Bleaching treatment, the biggest problem before the advent of whitening teeth showing an opaque, dull white, is the so-called white teeth as white as plaster. This is because the traditional decolonization process, the protection dental instruments of the enamel, damage to the compactness of the tooth surface. Cold light whitening technology appears to solve this problem.

Under the cold light of the catalytic whitening agent contained in the photosensitive material can greatly accelerate the teeth bleaching process, so that the original need for a dozen hours of the treatment process, reduced to only 30 minutes did not destroy The causes and whitening of the black teeth enamel. BEYOND whitening agent in the United States, in addition to teeth bleaching agents, in particular, added a high-tech silicon material with a diameter of 20 nm, this silicon material, and further strengthen the tooth surface enamel, teeth bleaching, it is also to enhance the gloss, whitening especially vivid and natural.

When teeth after tooth extraction

The best time of the teeth after tooth extraction generally according to the position of pulling teeth and tooth morphology, especially the root of the number of how many to decide. Such as in front or single premolar tooth after a month, such as wound healing, and alveolar concave long flat, modulo teeth; posterior teeth is more than double the root or the root of teeth, tooth extraction wound large The alveolar concave deep and wide, slow wound healing alveolar concave long usually take about 2 months before the modulo teeth. Such as premature modulo, the alveolar concave wound is not long flat dentures do not close together, the impact of denture quality.

On the contrary, more than 3-6 months after tooth extraction teeth, the relative elongation of the teeth to the edentulous ridge, or the tilt of adjacent teeth, missing teeth and gaps, missing teeth gap narrowing smaller, causing the denture difficulties. In addition, long-term missing teeth, can bite relationship disorder, chewing function, weakened in turn will affect the digestion dental instruments and absorption of food, unhealthy.

Therefore, the best dental time: Under normal circumstances, about 2 to 3 months after tooth extraction, dental more appropriate, this is because the tooth extraction wound completely healed at the need for a process. If the wound does not have long good teeth, due to the absorption of alveolar bone, tooth extraction wound also changes, there will be gap between the denture and the gum tissue, resulting in food impaction, bad breath, dentures loose and Orthodontic correction there an age limit not solid, you may want to re-install.

During the extraction, the denture can not be too long, more than six months are not false teeth, and surrounding good teeth are more or less a little tilt to the missing teeth gap will affect the future dental restorations.

Why invisible orthodontics would be so popular?

Traditional orthodontic tooth device, giving the feeling of "beak steel teeth. Many adult patients are daunting. Transparent invisible orthodontics is a new 3D stereoscopic computer technology, tailor-made a series of nearly undetectable transparent denture to complete the entire orthodontic treatment. Whether it is due to crowded teeth, gaps, or traditional treatment and then shift the teeth are fully regain the smile.

Invisible braces because there is no traditional treatment process in the wire and bracket, does not affect the appearance of the outstanding merits of widely favor of the United States teeth. Oral Center experts, this invisible appliance inherited malocclusion correction of the concept of dental medicine, computer-aided three-dimensional diagnosis, the perfect combination of personalized design and digital prototyping technology.

Compared to traditional dent facial deformity invisible appliance, do not need the brackets and wire, using a series of invisible appliance, the invisible appliance made by the safety of flexible transparent polymer materials, so that the treatment process almost in dental instruments others no aware, does not affect daily life and social development. Meanwhile, the bonded brackets, adjust the arch wire cumbersome, greatly simplifies the clinical procedures, save time and effort of the entire treatment process.

Invisible orthodontics is a high-tech technology in the current international field of orthodontics. Angel’s invisible braces better highlight the advantages, but do not apply to everyone, the main utility in mild to moderate tooth deformity.

Is particularly worth mentioning is the bracket invisible appliance can be carried out according to the patients with maxillofacial morphology personalized design, each pair Orthodontics of Note of appliance production in the three-dimensional computer image technology to simulate tooth movement, tooth wear into there will be feel the force, and the location of the mobile appliance design, usually every two weeks to replace an appliance, from the initial deformed state of the teeth will gradually move to the normal arrangement of the state, the correction of the length of time depends on the patients with malocclusion serious extent, it normally takes six months to a year or so.
