A clinical study was carried out on 250 joints of 222 patients with temporomandibular disorders with special reference to the relationship between disk position and bony changes. The joints were classified into 5 types, according to the classification proposed by the Japanese Society of TMJ. The joints with type III and type IV disorders were subdivided into III ADR (anterior dis-placement with reduction), III ADNR (anterior displacement without reduction) and IV N (no displacement), IV ADR, IV ADNR, respectively, by the disk position. Disk displacement with/without reduction was observed in 76% of the joints. Type III ADNR showed the highest incidence. The incidence of bony changes were 34.5% in 87 joints with ADNR and 17.5% in 103 joints with ADR, whereas these changes were noted in only 3 joints exhibiting no disk displacement, indicating that the bony changes are associated with the severity of disk displacement. The female-male ratio was 1:2.3, and was higher in joints classified into type I and type IV ADNR. The mean age was 33.5 years, and was significantly higher in joints exhibiting bony changes in both ADR and ADNR groups. The mean period before visiting our clinic was 33 months, and was significantly longer in type IV ADR joints than type III ADR joints, and was shorter in type IV ADNR joints than type III ADNR joints. The chief complaint was pain in 58.4% of the joints studied. Pain was the chief complaint significantly more often in type IV ADNR joint than III ADNR joint. The maximum mouth opening was significantly smaller in ADNR joints than the other type of joints, but it was not related to bony changes. The treatment was effective in 60.3% of the joints, and was least effective in joints with bony changes.
