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chromium molybdenum alloy, etc., but because of biological and mechanical properties of the defects have gradually been replaced by titanium.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.
