Obwegeser II method and Rigid fixation conserving the condylar position has been performed on 5 patients with severe mandibular prognathism, and we obtained the result after the follow up study follows. 1. Obwegeser II method is considered to move the distal segment passively when surgical correction of severe open bite correction and large amount of set back above 15mm is needed. 2. In one case that has more change of condylar position after operation, documented immediate post-operative relapse have been occurred 3. In the others that have adequate control of condylar position, passive set back and firm skeletal fixation, more functional and esthetic improvement and more post-operative stability has been achieved

Defects due to mandibulectomy often cause hard and soft tissue loss and result in esthetic problems and functional disorders such as mastication, swallowing, and pronunciation. After the mandibular reconstruction, several complications including loss of alveolar bone can cause limitations in maintenance or supporting of removable prosthesis. For these patients, implant-supported fixed restorations have been an appropriate prosthetic restorative method. In this case report, we report the patient who underwent mandibulectomy and mandibular reconstruction owing to oral cancer, and then restored the current dentition functionally and aesthetically by applying zirconia frameworks and monolithic zirconia crowns by computer-aided design and computer-aided manufacturing.

The contemporary two-jaw surgical approach usually involves a Le Fort osteotomy of the maxilla and a ramal osteotomy of the mandible with 3-dimensional repositioning of the jaws as well as the occlusal planes. After making the surgical treatment plan. the surgical movements are duplicated in the model surgery. During this procedure, reference poings and lines are drawn on the base of the models over the dental arch and sawcuts are mads according to these marked osteotomy lines. This technique, however, has been found to be inexact. especially when the laws are moved in several dimensions simultaneously. To overcome this. different methods have been developed for an accurate repositioning of the jaws as planned. A new appliance. Surgical Jaw Relater, has been devised by th8 author for the simple 3-dimensional relocation of the upper and lower models, resulting in the easy construction of the splints such as centric relation splint, intermediate and final splint. This article describes an introduction and a clinical application of this appliance. Through the application of this system to the orthognathic cases including two-law surgery. it is proved that the row device is very clinically useful.

The pediatric condylar fracture occurs very frequently in the mandible, but this injury is occasionally ignored due to difficulty of diagnosis and no cooperation of patient. The adequate initial diagnosis and active treatment must be performed because delayed and improper treatment lead to possible severe complication such as TMJ ankylosis and reta rdation of mandibular development. Most pediatric condylar fracture is mainly performed by the conservative or functional treatment, but it may be required open reduction according to cases. In this study, activator is applied for functional treatment of pediatric condylar fracture and fair recovery of jaw function is acquired.

Skeletal relapse is known as a complication following orthognathic surgery of mandibular prognathism and occurring during intermaxillary fixation period. Therefore relapse of teeth and skeleton during intermaxillary fixation period is considered as a important problem of orthognathic surgery. In this study, cephalolateral radiographs taken at pre-operation, immediate post-operation and after release of intermaxillary fixation were measured for evaluation of dental and skeletal relapse in 30 cases. The cases were classified as screw fixation group and plate fixation group, then we compared magnitude of dental and skeletal changes of each group. The results were as follows 1. The $\underline{1}$ SN angle increased at immediate post-operation with a mean value of $0.12^{\circ}$ and at intermaxillary fixation period with a mean value of $0.43^{\circ}$ (p>0.05). 2. The $\overline{1}$ MP angle decreased with a mean value of $0.14^{\circ} at immediate post-operation and with a mean value of $1.28^{\circ} during intermaxillary fixation period but there were not significant difference(p>0.05). 3. There were not significant difference in magnitude of dental position changes between screw fixation group and plate fixation group(p>0.05). 4. Gonial angle increased with a mean value of $0.62^{\circ} during intermaxillary fixation period. Each group showed changes of gonial angle during intermaxillary fixation period but there were not significant difference(p>0.05).

Chin is located on most prominent portion of the face, so make more important esthetic value in impression. So historicaly, many authors had made efforts on correction of deformed chin, termed genioplasty. But those technique have been performed on limited cases, which have normal shape or width of chin. In the cases with more narrow or short chin, location of mental foramen or root of incisors restrict the use of such technique. But modified genioplasty technique we used can be performed without any restriction and change of frontal profile of chin. So we report a case that was performed with modified horizontal step osteotomy for advancement genioplasty, which had been reported by Hinds and Kent, with some complications.

This study was carried out to observe the development of the autonomous skeletal development of the Tridentiger trigonocephalus. Seven days after hatching, the skeleton of the two line cranes began to ossify at premaxillary, maxilla and dentary when the average total length was 4.44 mm (n=5). At thirteen days after hatching, the frontal, parietal, and epiotic ossicles were observed in the cranium when the average total length was 5.62 mm (n=5). At thirty-two days after hatching, actinost and post cleithrum were ossified at the shoulder when the average total length was 11.8 mm (n=5). At forty days after hatching, the lateral ethmoid of the skull was ossified with an average total length of 13.3 mm (n=5) and all skeletal development was completed.

Recently, jawbone osteonecrosis has been largely reported as a potential adverse effect of bisphosphonate (BP)administration. Currently available published incidence data for BRONJ are based on retrospective studies and estimates of cumulative incidence range from 0.8 to 12%. The mandible is more commonly affected than the maxilla (2:1 ratio), and 60-70% of cases are preceded by a dental surgical procedure. The signs and symptoms that may occur before the appearance of clinical evident osteonecrosis include changes in the health of periodontal tissues, non-healing mucosal ulcers, loose teeth and unexplained soft-tissue infection. Tooth extraction as a precipitating event is a common observation. The significant benefits that bisphosphonates offer to patients clearly surpass the risk of potential side effects; however, any patient for whom prolonged bisphosphonate therapy is indicated, should be provided with preventive dental care in order to minimize the risk of developing this severe condition.
