Treatment of TMJ Syndrome (collapsed bite) in Japanese Patients

Abstract

Among various types of mutilated abnormal occlusion obserbable in Japanese, some of those cases show diasthema or prognathism of auteriors, and other symptoms due to the decrease of oral volume, and seem to be impossible to treat due to imbalance existing between load being applied by masticatory musculature and relatively weak support provided by periodontium.
It was, however, tried to treat such cases with a long term basis. Treatments included general check-up and local check such as plaque control, periodontal and endodontic treatments, bite raising, minor tooth movement, and so on. This report was dealing with the treatment of such difficult cases which were eventually treated favorably. And, it should be noted that maintenance of centric stops and prevention of lateral interference were the important factors for a long term prognosis of occlusal stability.
