Purpose: The aim of this study was to evaluate primary treatment in the patients with disk displacement without reduction and no osseous changes. Subjects and Methods: The improvement proportion during three months after onset of treatment was compared in the four groups, 1st group, intraoral a dministration of non steroidal anti inflammatory drug (NSAIDs): 2nd group, NSAIDs and mounth opening exercise: 3rd group, arthrocente sis: 4th group, a combination of arthrocentesis and a single injection of steroid. The subjects analyzed totaled 99 patients consiting of 25 in 1st group, 23 in 2nd group, 28 in 3rd group, and 23 in 4th group. Result: The improvement rate was 40% in 1st group, 44% in 2nd group, 36% in 3rd grop, and 30% in 4th group. Conlusion: In terms of improvement rate, no significance was found among 4 groups. However, a combination of intraoral administration of NSAIDs and mouth opening exercise could be most appropriate when primary treatment for TMJ closed lock without OA is evaluated.
