A number of panoramic radiographic images of the condylar head taken at various horizontal angulations were compared. A small artificial osteophyte was attached to the eight different portions of the condylar head and a small hole was created in four different portions of the condylar head. Three oral and maxillofacial radiologists evaluated the panoramic condylar images. The results were as follows : 1. Osteophytes in the superomedial, anterocentral and anterolateral portions could be detected easily, but those in the lateral, superolateral and medial portions were very hard to identify. 2. The greater the condylar horizontal angle, the easier it was to detect an osteophyte. But there was no statistically significant difference except between 0 and 40 degrees of horizontal angulation. 3. Holes in the anterocentral and superocentral portions could be detected easily, but those in the lateral and medial portions were very hard to identify. There were no differences between the various condylar horizontal angles.

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

Fractures of the mandibular condyle are among the most frequently occuring facial bone fractures. Anatomical structures around the joint inhibit the ideal reposition of the fragments, so variable treatment modalities have been tried selectivly. There can be functional disturbances postoperatively, and normalization of joint function must be considered primarily in treatment planning. Secondly, the possible joint ankylosis and facial deformity following developmental disturbance of facial skeleton must be considered. The authors reviewed 73 patients treated in Dept. of Oral and Maxillofacial Surgery. Inje College of medicine Pusan Paik Hospital from 1981 to 1987. Also literatures were reviewed, and we obtained some reference points concerning the selection of the treatment modality and prevention of the possible complication.

It is essential to record maxillomandibular relationship accurately for the harmony of esthetic and function in complete denture. Gothic arch tracing visually demonstrates the movement of the mandible, and is useful to establish accurate and reproducible centric relation. Proper retention and stability of complete denture in patients with severe alveolar bone resorption is difficult to attain. In such case, the closed mouth impression technique might be recommended. The denture border and impression are determined by patient's physiologic movement in the closed mouth impression technique. And, denture peripheral border is entirely closed with oral mucous membrane. This report presents satisfactory complete denture restoration using closed mouth impression technique and gothic arch tracing in patients with mandibular condyle fracture and severe absorption of mandibular alveolar ridge.

When the mandible performs opening movement, the condyle-disk complex conducts sliding movement along the articular eminence. Thus, anatomic configuration of articular eminence is very important to normal movement of TMJ. The purpose of this study was to measure the posterior slope of the articular eminence and evaluate the effect of a pathologic bone change in the condylar head on the stiffness of articular eminence, and compare the differences of the articular eminence slope by gender and age using dental cone-beam CT. As using i-CAT Cone-Beam Computed Tomography, the CT images of 204 TMJs of 102 patients(43 men and 59 women, mean age: 37.7 years) who were diagnosed at Wonkwang University Sanbon Dental Hospital were evaluated. All images were converted into a TMJ analysis mode to observe the continuous sagittal section images and coronal section images of the joints. To observe and assess bone changes in the condyle, three dentists measured the stiffness of the articular eminence on the same images, and when two of the three dentists agreed on their reading, these results were adopted and recorded. The articular eminence slope, considering the condylar anatomic configuration, was measured in three regions, namely, lateral part, central part, and medial part of the condyle. In the cases of a normal condyle(NCBC) and a condyle(CBC) with bone change, the articular eminence slopes were $57.0^{\circ}$(NCBC) and $51.8^{\circ}$(CBC) at the medial part, $57.9^{\circ}$(NCBC) and $52.4^{\circ}$(CBC) at the central part, and $55.1^{\circ}$(NCBC) and $49.5^{\circ}$(CBC) at the lateral part of the condyle. And the articular eminence slope of the condyle with bone change demonstrated less steepness than that of normal condyle (p<0.05). The articular eminence slope showed mediolaterally that it was the steepest at the central, followed by at the medial, and at the lateral (p<0.05). There were no significant differences by the gender and the age (p.0.05).

Stabilization splint therapy Precedes orthodontic intervention to enable the operator to find a 'true' centric(which is stable and comfortable), to test the patient's response to a change in the occlusion, prior to embarking upon a complex course of occlusal therapy : and finally, to see if the centric relation position can be stabilized. For this study, 47 malocclusion Patients enrolled for orthodontic treatment at the Department of Orthodontics, College of Dentistry, Chosun University comprised the malocclusion group, little variation of growth factor by the second molar eruption. They had Cr-Co discrepancy beyond normal range. For each patients the stabilization splint with mutually protected type of occlusal scheme was applied for 3 months. Condylar positions in CR and CO were measured using Penadent articulators, Panadent condylar position indicator(CPI), and transcranial projection before & after stabilization splint therapy. On the basis of this study, the results of this study were as follows 1. In all samples using CPI, there were statistical significances in CR-CO discrepancy(p<0.001) both before 8t after stabilization splint therapy. 2. In Rt and Lt+Rt/2 of superior joint space using transcranial projection, there were statistical significances in CR-CO discrepancy({<0.05) before & after stabilization splint therapy. 3. In supero-inferior components using CPI, there were statistical significances in CR-CO discrepancy(p<0.01) before & after stabilization splint therapy. 4. In all components except Rt using transcranial projection, there were no statistical significances in CR-CO discrepancy(p>0.05) before & after stabilization splint therapy. To sum up, CPI might be more effective than transcranial projection to reveal the changes between CR-CO discrepancies and stabilization splint might be more useful appliance for displaying the vertical changes, than the antero-posterior changes, of condylar position.

Mandibular fracture is less common in children than in adults. However, children are more susceptible to ankylosis and developmental disorders, and don't respond as well to intermaxillary fixation compared to adults. On the other hand, bone fracture is healed more quickly in children and complications are scarce. Mandibular fracture in children is usually treated successfully with acrylic splint therapy with or without the use of eyelet wires and intermaxillary fixation. Severe complications that include ankylosis and developmental disorders may occur. The frequency and severity of such complications can be mitigated with a shorter duration of intermaxillary fixation and good post-operative care. Encouraging mandibular physical therapy by increasing patient motivation may be necessary in such cases where the patient's response is poor and the duration of intermaxillary fixation increases; when the patient is unable to undergo physical therapy, or when intermaxillary fixation is not necessary with the patient showing only minor symptoms such as trismus. In this case report, a 6 year-old girl with bilateral condylar fracture was treated with elastic in both the upper and lower jaws to allow mandibular physical therapy using a Benoist's appliance, which allows opening, lateral, and protrusive retrusive movements of the mandible. A 7-month follow-up showed beneficial therapeutic effects such as increased mandibular movement and prevention of condylar ankylosis.
