  • This is a case report about patient who had suffered from degenerative joint disease and treated by TMJ reconstruction with condylar prosthesis. The patient visited Korea University An-am hospital on 2007 complaining symptom about both TMJ pain, mouth opening limitation and open bite. From CT view there was severe resorption of both condylar head, therefore condylar prosthesis reconstruction was planned. After 3D RP model analysis for preparation, the patient was operated under general anesthesia for condylar prosthesis reconstruction and the symptom was alleviated. (increased mouth opening, reduced anterior open bite, full mouth occlusal contact achieved) Follow up was carried out monthly, but after this, patient refused follow up. After 26 months from the operation, the patient revisited for anterior open bite. In clinical evaluation, occlusal contact was remained, but anterior open bite was relapsed. From cephalometry analysis, severe resorption of glenoid fossa was found. Therefore, Autogenous disc reconstruction with alloplastic material was planned on August 2009. After another surgery, condylar prosthesis was regained its normal position in glenoid fossa, and occlusion was recovered properly.

  • The following results were abtained based on the research of the occlusal patterns among 1074 handicapped persons (cerebral palsy: 46, mental subnormality: 619, deafmute: 285, blind: 111, childish autism:8, cleft lip and cleft palate:3, polimyelitis:2) of the age between 6 and 23 in Chollanamdo, Korea, in comparison with a normal group of 1048 children of the age between 6 and 15 selected at random in J primary school in Gwang-ju City. 1. According to Angle's malocclusion classification, all the handicapped groups, except the cerebral palsy and the blind, showed a higher prevalence of malocclusion than that of the normal. Especially the prevalence of Class II, devision 1 malocclusion in the cerebral palsy was the highest, and the prevalence of Class III malocclusion in all the handicapped groups was higher than that of the normal group. Among these groups the highest prevalence of Class III malocclusion was in the Down's syndrome group. 2. On the the abnormal pattern of the anterior region, there was no significant difference $(P\leqq0.05)$ between the normal and the cerebral palsy, the deafmute, and e blind. The open bite $(7.27{\pm}1.04\%)$ and the cross-bite $(32.7{\pm}6.33\%)$ of the Down's syndrome wire higher than that of the normal, and the forward position of the mandible could be recognized in the Down's syndrome group. 3. On the midline position of the dentition, all the handicapped showed the same percentage of deviation, but the degree of mandibular shift to the right $(20.00{\pm}5.39\%)$ or left $(10.91{\pm}4.20\%)$ was higher than that of the normal only in the Down's syndrome group. 4. On the abnormal pattern of the posterior region, the cross-bite of the Down's syndrome was higher than that of the normal by $20.00{\pm}5.39\%$, the cross-bite of the cerebral palsy and the cross-bite and the open bite of the mental subnormality were slightly higher than that of the normal. The other handicapped groups showed no significant difference $(P\leq0.05)$ to the normal.

  • 개방교합이 있는 환자는 치아접촉 및 수직피개의 감소를 나타내며 교합평면의 부조화, 저작 곤란, 언어 장애, 외모 변화 및 정상보다 낮은 교합력을 가지는 경우가 많다. 교합이 완성된 성인에서 측두하악관절장애로 인해 발생한 개방교합은 원인요소의 제거 또는 관절상태의 안정화가 먼저 이루어진 후 교합 수정이 이루어져야 하며, 이를 위해 교정치료, 교합조정, 보철 치료, 외과적 치료법 등이 있다. 본 증례보고는 교합이 완성된 성인에서 하악의 변위로 인해 개방교합이 발생한 두 명의 환자에서 교합 변화의 원인을 추정해 보고 원인에 따라 다른 치료 접근방법에 대해 살펴 보는 것이다. 관찰한 환자 중 한 환자는 측두하악관절의 안정화 후 교합조정을 통하여 기능적인 면과 심미적인 면에서 만족스러운 결과를 얻을 수도 있었기에 보고하는 바이다.

  • The occurrence of osteochondroma, osteoma in mandibular condlye is rare. Sign and symptoms of enlargement of condyle are open bite, cross bite, myofascial symptoms, facial asymmetry. They are treated via condylectomy, subcondylar ostetomy, etc. We treated osteochondroma with condylectomy, osteoma with condylectomy & arthroplasty with titanium mesh & resin ball. Followings are the results 1. Condylectomy of osteochondroma resulted in good function & esthetics except slight deviation of mandible to the operation side during mouth opening. 2. Condylectomy & arthroplasty with titanium mesh & resin ball resulted in good function & esthetics & no deviation of mandible.
