The author examined 206 temporomandibular disorders patients, who visited department of Oral Diagnosis and Oral Medicine in Seoul National University Hospital during the period from May 1st 1987 to April 30th 1988, clinically and radiologically and with prepared questionnaire. By clinical and radiological examination, the patients were divided into 2 groups(the patients with temporomandibular joint internal derangement and myofacial pain dysfunction syndrome or with myofacial pain dysfunction syndrome: the patient with temporomandibular joint internal derangement only). The symptom severity index and contributing factors were examined with the questionnaire, and differences in 2 groups were studied. The conclusions are followings : 1. The symptom severity index presenting the severity of symptom was higher and the scope of symptom was wider in the patients with temporomandibular joint internal derangement and myofacial pain dysfunction syndrome or with myofacial pain dysfunction compared to the patients with temporomandibular joint internal derangement only. 2. Emotions, behaviors, cognitions, and social factors were more undesirable in the patients with temporomandibular joint internal derangement and myofacial pain dysfunction syndrome or with myofacial pain dysfunction syndrome than the patients with temporomandibular joint internal derangement only.

Purpose: The effect of orthognathic surgery on the temporomandibular dysfunction has been controversial. The purpose of this study is to prove statistically that early removal of fixation plate at postoperative 2 weeks with active exercise of mouth opening could relieve preoperative temporomandibular dysfunction and reposition of temporomandibular joint. Patients and Methods: All 28 subject patients underwent mandibular setback with BSSRO in Kyunghee medical center by one surgeon. The fixation plates used for rigid fixation were removed at postoperative 2 weeks and we had the patients excercise active mouth opening with intermaxillary rubber rings for the guiding proper postoperative occlusion. Temporomandibular symptoms were checked and radiographs were taken before surgery, within a month after surgery, six to twelve months after surgery respectively. Results: The temporomandibular dysfunction symptoms were relieved after the surgery and the condyle was displaced inferior-posteriorly immediate after surgery and repositioned toward its original position during follow-up periods. Conculusion: Orthognathic surgery may benefit temporomandibular joint dysfunction by obtaining a postoperative stable occlusion and more physiologic neuromuscular function. The early removal of fixation plates after BSSRO could reposition the temporomandibular joint to physiologic position and relieve the symptoms of temporomandibular dysfunction by permitting movement of proximal segment.

Purpose: The purpose of this study is to prove that orthognatic surgery on asymmetric prognathism patients improve the temporomandibular dysfunction. Materials and methods: All 30 patients underwent mandibular setback with B-SSRO including 22 patients Le Fort I surgery in KyungHee medical center. Preoperative and postoperative PA cephalograms & transcranial radiographs were measured midline deviation in Mx and Mn, occlusal canting change, condyle position, the temporomandibular dysfunction were checked before surgery, within 1 month after surgery, $3{\sim}6$ months, 12-24 months after surgery respectively. Results: The temporomandibular dysfunction were relieved after surgery in 17 patients of 25 patients. Conclusion: Orthognatic surgery may benefit the temporomandibular joint dysfunction in facial asymmetry patients by obtaining a postoperative stable occlusion and better physiologic neuromuscular function. Specially impovement of occlusal canting may reduce condyle displacement of midline deviation side and the temporomandibular joint dysfunction.

14 patients, whose were attacked pain dysfunction syndrome of temporomandibular joint in Dental College Infirmary, Seoul National University from June 1970 to Dec. 1971, were examined regarding to clinical observation and electromyographical analysis. This paper established the followings: 1. Especially young female was more frequently attacked by pain dysfunction syndrome of Temporomandibular joint. 2. It is suggested that most of joint pain was occurred initially in opening mouth and forcible bite, and left side is more attacked than right side. 3. It was possible that this dysfunction can be occurred by open-bite, premature contact and ill-fitting prosthetic restoration. 4. Hoby, habit and bruxism as causal factors are not markedly related with this dysfunction. 5. Pain attacked regions, in most patients, are preauricular, joint itself, infra-auricular, cervical and external auditory meatus region. 6. In electromyographical studis, the musle activities of affected side of pain dysfunction syndrome are more strong than that of opposite side.

A clinical evaluation was made on teeth in 113 subjects from ages 19 to 23 with Angle's Class I occlusion who were free from prosthesis, orthodontics, and occlusal equilibration. The study was made to determine if there was a relation between the type of occlusion, non-working contact and temporomandibular dysfunction. From the foregoing study, the author obtained the following results. 1. In lateral excursion, there was not any significant difference between bilateral canine protected occlusion (31%), bilateral group function (32.7%), and mixed type (34.5%). 2. Only 10 of 113 subjects studied had non-working side tooth contacts (8.2 per cent). 3. Twenty per cent of subjects with non-working side contact showed temporomandibular joint dysfunction. 4. Non-working side contacts were not observed in subjects with canine guided occlusion. 5. It would be premature to relate the type of occlusion on working side directly to temporomandibular joint dysfunction.

This paper offers an approach to physical therapy and rehabilitation procedure for the temporomandibular joint dysfunction (TMD). Forms of physical therapy are used in the treatment of chronic musculoskeletal pain conditions that include TMD joint disorders. However, there still remains a void in the study as to the various rehabilitative protocols used on those patients with TMD. Recent evidence in clinical trials show that physical therapy is helpful for patients with TMD. Exercise programs designed to improve physical fitness had beneficial effects on TMD pain and dysfunction. This study establishes treatment procedures of physical therapy and provides a method of evaluation for patients with TMD disorders.

저자는 악간절기능장애의 소견을 가진 환자 75명과 악관절기능장애의 병마 및 현증이 없는 정상인 75명을 표준화된 조건하에서 두부축방향방사선촬영을 하여 과두수평각과 initial 및 final depth of cut를 측정하고 통계학적으로 분석한 결과를 다음과 같이 요약할 수 있었다. 환자군과 정상군, 환측과 비환측에 있어 과두수평각과 initial 및 final depth of cut는 통계학적으로 유의한 차가 없었으므로 두부축방향방사선사진은 임상에서 악관절기능장애의 유무 및 환측과 비환측의 감별에 이용하기에 부적합한 방법이라 사료된다. 본 연구의 계측치는 편차가 심하므로 환자마다 과두수평각을 측정하여 이각에 맞추어 악관절단층촬영을 해야 한다고 사료된다.

Purpose: To evaluate osseous changes of temporomandibular joint (TMJ) in patients with rheumatoid arthritis (RA) using cone-beam computed tomography (CBCT) and to correlate the imaging findings with the severity of TMJ dysfunction, clinical findings, and laboratory findings. Materials and Methods: This study consisted of 28 subjects, including 14 RA patients and 14 controls, who were scheduled to undergo CBCT imaging for the diagnosis of a complaint not related to or affecting the TMJ. The Fonseca's questionnaire was used to assess the severity of TMJ dysfunction. Rheumatoid factor (RF) and the erythrocyte sedimentation rate (ESR) were assessed in the RA patients. CBCT was then performed in all subjects and osseous TMJ abnormalities were assessed. Results: According to the Fonseca's questionnaire, 14.3% of the patients had no TMJ dysfunction, while 50%, 21.4%, and 14.3% had mild, moderate, and severe dysfunction, respectively. RF was positive in 64.3% of patients, and the ESR level was high in 100%. Imaging findings revealed a statistically significantly higher prevalence of erosion (85.7%), flattening (89.3%), osteophyte formation (32.1%), subchondral cyst (32.1%), sclerosis (64.3%), and condylar irregularities (28.6%) in the RA patients than in the controls. No correlations were found between CBCT findings and the clinical findings, the severity of TMJ dysfunction, disease duration, or laboratory results. Conclusion: RA patients might show extensive osseous abnormalities with no/mild clinical signs or symptoms of TMJ dysfunction that necessitate TMJ imaging for these patients. CBCT is a valuable and efficient modality that can assess osseous TMJ changes in RA patients.
