Anterior disc displacement is a common subtype seen in temporomandibular disorders (TMD) patients. It may cause mandibular movement disorders, such as clicking of joint, intermittent closed lock, limitation of mouth opening, etc. These disorders may affect the life qualities of patients. Anterior disc displacement may also cause mandibular malformations, especially among adolescents, which may affect the growth of condyle, therefore may have a correlation with mandibular retrusion or mandibular deviation when grown up. This paper going to review the influences of anterior disc displacement on oral mandibular function and morphology and their biological mechanisms.

A study mentioned impaction related wisdom teeth are frequently seen age groups of 22- 32 years of age, taking 72% of statistic data, then corresponding with development time and growing processus of wisdom teeth. The types of mandibular wisdom teeth inclined to cause eruption complications take 83% of these cases are grouped in class II, according to Archer’s classification. The position A, and B are locating the teeth at the end of their eruption time from alveolar gingival level and are prone to cause local complications the whole situations take 94% of cases. The vertical axia orientation of these cause wisdom teeth will largely influence on the course of the following complications.

temporomandibular joint (TMJ) replacement is encouraging, with acceptable improvement of treatment outcomes in terms of both pain level and jaw function. This is a case report on patients who suffered from degenerative joint disease and ankylosis after mandibular condyle fracture or prior TMJ surgery and were treated by TMJ replacement with condyle prosthesis. We obtained good results from the procedures, including total TMJ replacement.]]>

The free iliac rest flap based on the Deep Circumflex lilac Artery (DCIA) and Vein (DCIV) has proven to be a useful technique with a high rate of success. It provides a large segment of strong bicortical bone that was sufficient to reconstruct up to two thirds of mandible and supplied by blood vessels with large and long enough to allow for consistently successful anastomosis. It also uses a donor site located for enough from the neck to allow two teams perform operation in the same time with minimum of complication.

This study was to describe the use of inverted-L osteotomy of ramus and iliac bone graft for the management of mandibular deficiency in adult patients. From 2008 to 2010, 11 patients (aged 19 to 29 years) with mandibular deficiency underwent intraoral or extraoral inverted-L osteotomy of ramus and iliac crest bone grafting. Data were collected from the patients' records, photographs and radiographs. The height and width of the ramus were successfully expanded by inverted-L osteotomy and iliac crest bone grafting with minimal complications in all patients, resulting in significant improvement in occlusion and facial appearance. Our early results showed that the inverted-L osteotomy of ramus and iliac crest bone grafting is safe and effective, and should be considered as a good alternative for the patients with mandibular deficiency.

Garrès osteomyelitis is a specific type of chronic osteomyelitis that most commonly occurs in young patients, secondary to dental infection, and affects the unilateral side of the mandible. Bilateral mandibular Garrè's osteomyelitis is rare. In this article, a case of Garrè's osteomyelitis with bilateral mandible is reported. Its etiology, clinical pathologic features, diagnosis, differential diagnosis, and treatment methods are discussed by reviewing relevant literature.

For many years, intermaxillary fixation using arch bar has been operated in treatment of mandibular fracture patients. But it has many complications including injury of operators and assistants cause by wire, inflammation of periodontium. For that reasons alternatives are required; osteosynthesis technique using mini plate, intermaxillary fixation using IMF screws have been available. Treatment by arch bar fixation, however, is still valuable to treat craniomaxillary fracture patients. The purpose of this study is to know effect arch bar on periodontium and influence gingival gel on periodontium applied by arch bar. 40 mandibular fracture patients are monitored. 30 patients were applied by arch bar, 10 patients were not. And the former were classified by 3 categories; Nano vitamin and Mastic gel were applied to 10 patients respectively and any gingival gel was not used to 10 patients. Clinical attachment level, bleeding on probing and periodontal depth of each group were measured and compared before operation and on 2 weeks and 6 weeks after operation. Mann-Whitney U test was used to analyze result which leads to this conclusion. 1. Whether arch bar is applied or not, treatment of mandlbular fracture gave rise to gingivitis, but 6 weeks after operation, gingivitis is restored to the same level as the state before operation. 2. More severe gingivitis appeared when arch bar is applied to mandibular fracture than when it is not. 3. Both gingival gel used in this study can reduce gingivitis which can be caused by arch bar. 4. In this study, Mastic gel is more effective for prevent gingival inflammation cause by arch bar than nano vitamin. In regard to this result, gingivitis is considered to be available because it is reversible and does not induce periodontal disease. Gingival gel is regarded to be helpful for patients applied by arch bar to feel less discomfort.
