How to avoid the porcelain teeth impaction of food?

Often encountered in the porcelain restoration prosthesis failure and rework due to food impaction, how to avoid food impaction? Doctors and technicians are concerned about the pressing problem as it relates to the vital interests of patients, doctors, and mechanics. To solve this problem, need doctors, patients, technology closely with the three, it would be difficult to achieve satisfactory results.

Food impaction have a great relationship first and the patient's oral occlusal interference tip of the co-tooth if functionality tip is outreach of the occlusal surface of the denture and natural teeth adjacent point gap, the doctor should be emphasized in the wear of teeth grinding the tip of this feature, to reduce its bite and the slope of the cusp, the mechanic shall make a reasonable and adjacent teeth occlusal surface outreach gap, expand dental instrument the adjacent points at the buccal, lingual outreach gap, neighbor was a small area contact form oval, watermelon seeds, like shrink in height between the middle third of the teeth and cut one-third of tightness through the 0.1mm articulating paper slightly block sense is appropriate.

Secondly, food impaction and the doctor tooth preparation. Common due to the co-teeth long-term elongation defect of dental porcelain crown restoration, the doctor should pay attention to the coordination of the preparation of the abutments with adjacent teeth adjacent points, otherwise it will form a wedge-style food impaction. Normal adjacency relationship between tooth preparations should not wear the adjacent teeth. However, in practice, due to clinical factors, tend to "Deeply entrenched" dental implant damage the adjacent teeth can be seen in the observation of an impression-chip section, the doctor should wear at the adjacent points above requirement, the dressing is worn the adjacent surface, and then take the work mode. Otherwise it will form a wedge-type impaction, if a doctor is not in preparation for trimming, the mechanic should remind the doctor in the wear of teeth adjacent surface finishing, and to avoid rework and repair fail due to food impaction.
