Objective. The objective of this study was to assess long-term 10-year results in comparison with the short-term outcomes of nonsurgical treatment for the internal derangement of the temporomandibular joint (TMJ) with closed lock. Patients and Methods. The survey was conducted on 56 patients, 50 of whom responded. The age at first examination ranged from 13 to 75 years (mean, 33.2 years), and the pretreatment jaw opening was 30.3 mm on average. The short-term clinical outcome of nonsurgical treatment for 56 patients consisted of 42 successful and 14 unsuccessful cases. The mean follow-up period was 9 years and 10 months. All patients rated their pain level on a visual analog scale (VAS) and filled out a pain, jaw-dysfunction, and activities-of-daily-limiting (ADL) questionnaire before and at time of the survey. Jaw opening was also self-assessed. Pretreatment and post-treatment scores were compared and statistically tested, and the treatment outcome was judged according to our success criteria. The patients were also asked for a global rating of the subjective outcome at the survey. Last, long-term outcomes were compared with short-term clinical outcomes. Results. VAS was significantly reduced from 4.91 to 0.17 (P
