In recent years the relationship between occlusal stability, mandibular position and temporomandibular joint function has been greatly emphasized. Anterior repositiong splint has been used for the purpose of correcting a disk-condyle in coordination, so we have usually wed it in ease of the click of the temporpmandibular joint. We have used anterior repositioning splint in 28 patients who have chief-complain of click in symptoms of the temporomandibular joint arthrosis. At the patients who had long-lasting symptom and sign, late click or degenerative change of the temporomandibular joint, the anterior repositioning splint had less effect on than we had expected. So we are now to report that we must pay attention to use of anterior repositioning spint.

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 study was performed to investigate the influence of orthognathic surgery on the temporomandibular dysfunction in skeletal class III malocclusion. The temporomandibular joint status in 22 patients(mean age: 23.7 years) who received orthognathic surgery such as mandibular BSSRO(14 patients), maxillary Le Fort I osteotomy with mandibular BSSRO(8 patients) was evaluated by craniomandibular index. All these patients received orthognathic surgery at least 6 months ago. The mean score and standard deviation was obtained and compared with that of 22 normal individuals(mean age: 24.8years) by Student's t-test. In mandibular movement, the score of orthognathic surgery group was higher than that of the normal group. All the items except mandibular movement did not show any differences between the two groups.

In order to evaluate the effect of signs and symptoms of temporomandibular disorders on the bite force of anterior teeth, the author estimated a feature of maintaining the maximum bite force on central incisors in Korean 34 adult females with signs and symptoms of temporomandibular disorders (TMD group) and in Korean 31 adult females within normal masticatory function far from any sign or symptom of TMD (control group), and analyzed the data statistically. The obtained results were as follows: 1. There was not a significant difference of the maximum bite force on central incisors between TMD group and control group (P>0.05). 2. The duration of maintaining the maximum bite force on central incisors in TMD group was shorter than it in control group (P<0.01).

Objectives: The purpose of this review is to investigate the relationship between the extra meridians and the temporomandibular joint. Methods: Literature review on the eight extra meridians and theoretical considerations were performed with a focus on the relationship with the temporomandibular joint. Results: Extra meridians are crucial in the maintenance of the balance of the whole body, especially the structural balance of the anterior-posterior, left-right, superior-inferior, and interior-exterior regions. The foundation of extra meridians occurs in the lower abdominal area and the innate qi. Conclusions: Extra meridians are important players in the maintenance of the balance and harmony within the body, and may function cooperatively with the temporomandibula joint in its role to maintain the yinyang balance within the body.

Objectives: TMJ is the joint that connects the mandible to the skull, and it balances the body by holding the skull in the right position. The Meridian flows through the whole body. The objective of this study is to examine and clarify the relationship between the Temporomandibular Joint (TMJ) and the Meridian flow, especially around the TMJ. Methods: We reviewed the literature on the 8 Extra Meridians and the 12 Main Meridians around the TMJ. Results & Conclusion: Eight Extra Meridians keep the balance and harmony of the TMJ, and also play an important role in maintaining equilibrium of Yin and Yang of the whole body. The 12 Main Meridians, twelve Meridian Divergence (12經別) and Meridian Sinew also play an important role in the balance and harmony of the whole body based on the function of the Vicera and Bowels (臟腑). So it is conceivable that the role of TMJ is important in terms of health care.

In the case of the trauma on the maxillofacial region occurred, we think that one of the most important thing is recovery of the function as well as reconstruction of the anatomical form. Especially, it has been that the structure of the surrounded temporomandibular joint has a great possibility to cause mouth opening limitation when a bit of displacement is caused. Therefore, in the case of the trauma on mid-face we think that we treat it after complete evaluate condition of soft and hard tissue surrounding the articular disc as well as fracture site. We report results of our study, since we obtained good results from our study concerning the refixation of the zygomatic arch, high condylectomy, coronoidectomy and myotomy for the patient being suffered from the arthrosis of the temporomandibular joint caused by insufficient fracture treatment of zygomatic arch and coronoid process.

The author herein presents an unusual case of eustachian tube calcification masquerading as loose radiopacities in the temporomandibular joints on a panoramic image, creating a diagnostic challenge. The patient, a 72-year-old woman, presented to the dental service for implant treatment to improve her masticatory function. A cone-beam computed tomography scan was performed and reviewed by a board-certified oral and maxillofacial radiologist. The scan showed no evidence of calcifications in the temporomandibular joints; however, it revealed nodular calcifications within the cartilaginous portion of the eustachian tube bilaterally. Additionally, this report briefly reviews the differential diagnosis of calcified loose bodies in the temporomandibular joint and provides information that needs to be reinforced periodically.

Psoriatic arthritis is a chronic inflammatory form of arthritis that is associated with psoriasis. A 54-yr-old male with chronic psoriatic temporomandibular joint arthritis and myofascial pain was treated using methotrexate and a myofascial pain protocol. Jaw pain improved after 3 weeks, however, tenderness to palpation of muscles remained. Comprehensive evaluation and multidisciplinary clinical treatment is required for the treatment of patients with psoriatic temporomandibular joint arthritis.

Objectives: The aim of this study was to use four sets of success criteria to evaluate the outcomes of arthrocentesis treatment with hyaluronic acid injection in patients with internal derangement (ID) of the temporomandibular joint (TMJ). Materials and Methods: The study included 40 patients diagnosed with unilateral Wilkes stage III TMJ dysfunction. Clinical parameters, including maximum mouth opening (MMO) and pain during function, were evaluated preoperatively, 6 months, and 1 year after TMJ arthrocentesis. Outcomes were assessed and compared using four sets of success criteria from the following: the American Association of Oral and Maxillofacial Surgeons (AAOMS; MMO ${\geq}35mm$ and visual analogue scale [VAS] score ${\leq}3$), Murakami et al.'s criteria (MMO >38 mm and VAS score <2), Emshoff and Rudisch criteria (MMO ${\geq}35mm$ and >50% pain reduction), and patient self-reports (self-evaluation of treatment as successful or unsuccessful). Results: Significant improvements in MMO and pain reduction during function were observed between the preoperative period and 6 months and 1 year postoperatively (P<0.01). The success rates of treatment determined using AAOMS (52.5%), Emshoff and Rudisch criteria (57.5%), and self-reported patient criteria (40.0%) were similar. Application of the Murakami et al. criteria reported the lowest success rate (12.5%). Conclusion: The AAOMS and Emshoff and Rudisch criteria are consistent with patient expectations and can be used to assess treatment efficacy.
