The purpose of this study is to predict the change of the facial soft tissue following orthodontic surgery associated with mandibular prognathism. Twenty-one patients were selected who recieved orthognathic surgery in mandible only (13 cases) and in maxilla and mandible simultaneously (8 cases). Ages of the patients were over the 16.8 years. Lateral cephalometric head films were taken just before the operation and post operative film were used that of post-operative minimum 6 months. We evaluated the cases by two methods, 1:1 mean ratios and stepwise multiple regression analysis. The results were as follows. 1. The prediction is more accurate by stepwise multiple regression analysis than by 1:1 mean ratios. 2. The prediction by stepwise multiple regression equation is always available regardless the method of operation. 3. We can make a soft ware program for computerizing by obtaning the stepwise multiple regression equation.

Facial enlargement that produce asymmetry may occur at many site but those associated with the mandible are usually the most striking. According to the site of the deformity, mandibular asymmetry was classified as deviation prognathism, unilateral condylar hyperplasia, unilateral macrognathia, and maxillary asymmetry as vertical, horizontal and sagittal asymmetry. In the selecting of the surgical procedures of facial asymmetry, the most significant consideration are the magnitude of the deformity and the remaining potential of growth. Procedures used in treatment of facial asymmetry are condylectomy sagittal split ramus osteotomy, vertical ramus osteotomy, genioplasty segmental ostetomy and Le-fort 1 osteotomy. We have treated 9 patient with facial asymmetry by above procedures and results were good both esthetically and functionally.

The choice of the optimal time for secondary bone-grafting must depend on the tooth eruption stage than the chronologic age. And the success of alveolar graft is affected by the grafting materials and the appropriate orthodontic treatment. This is a case report of 2 bilateral alveolar clefts and 1 unilateral alveolar cleft, which impacted tooth was erupted through the alveolar grafted area.

In some individuals, facial asymmetry appears conspicuously and it causes esthetic problem with other several symptoms. It has been long that the authors have introduced the classifications and diagnostic methods of facial asymmetry. In this report, we will introduce more developed diagnostic method in two viewpoints. First, in diagnosis of facial asymmetry, we added the concept of mandibular independent growth unit, and studied that which unit tends to cause the jaw deformity. Second, we present improved three-dimensional diagnostic method for systemize spatial problem. Several surgical cases which are applicated by this diagnostic method will be also presented. Such cases will show the necessity of treatment on the etiopathogenic area.
DEEP BITE를 동반한 골격형 제Ⅱ급 부정교합의 치험례

Skeletal Class Ⅱ malocclusion with deep bite is difficult to manage properly. Generally the lower facial height is short and the curve of Spee is severe. We managed these cases as fellowe. 1) Tooth alignment through the pre-op. orthodontic treatment. 2) Surgically mandibular advanced with modified wafer. 3) Using the modified wafer, by rapid extrusion of posterior teeth, Curve of Spee was decreased during IMF. The rapid extrusion process is begun the IMF periods, thereby decreasing total treatment time. Our two cases result were satisfactory by means of more simple surgical technique and orthodontic treatment.

The growth and development of the mandible consists of condylar head, process, angular portion, corpus and alveolar process. This case is a result of mandibular corpus reconstruction in pubescence by the metal plate which defect was caused by the bomb. Two years after the reconstruction, one can notice the asymmetrical development of mandible. We present the case and the literature review.

An introduction of three-dimensional cephalometric analysis of facial asymmetry which we currently used is illustrated with a case of facial asymmetry due to deviation prognathism, Rt. side. Posteroanterior projection and submental-vertical projection were useful to measure and record the three-dimensional relationships of anatomic structures to one another in craniofacial asymmetry, rather than lateral cephalogram.

This is a report of mandibular defect in 14-Y-0 male patient due to traumatic avulsion, which is treated by functional treatment. Maintaining the proximal and distal segments of the mandible in their normal positions after avulsion or surgical removal of a portion of the mandible is important. Failure to do so will result in fragment rotation and drifting and scarring of tissues and absence of a bed for the graft is the another problem which complicate reconstruction. We used functional mouth opening guider for prevention of the above problems. The obtained results were as follows; 1. Normal occlusion and mouth opening pattern without lateral and medial displacement were observed. 2. Rigid fixation is possible because of prevention of prevention of fragment collapse and soft tissue constriction for bone grafting.

There can be many causative factors for open bite, and arthritides on temporomandibular joint can be one of those. Arthritides on temporomandibular joint are classified as: infectious, traumatic, inflammatory, degenerative and metabolic. Authors have examined two patients, who came in with open bites as their a chief complanits, and have found bone resorptions of mandibular condyles. Various diagnostic methods have resulted in diagnosis of rheumatoid arthritis and degenerative arthritis for each patient, and appropriate treatment planning has been established.
