Abstract

Loss of molar support and abnormal jaw relationship lead to occlusal disharmony and cause pathologic signs. Full mouth rehabilitations with reestablishment of occlusal schemes are needed. In this case, the 75 year-old female patient showed posterior bite collapse, irregular occlusal plane and Class II jaw relationship. By observing her profile and interocclusal distance, she was diagnosed as loss of occlusal vertical dimension. Treatment plan is to restore maxillay class I removable partial denture and mandibular fixed prosthesis and to establish vertical dimension and harmonious occlusal plane. Occlusal vertical dimension of 19 mm, which is obtained by 7.5 mm increase between maxillary right lateral incisor and mandibular canine, was established using temporary prosthesis via diagnostic wax-up. Patient adaptation with newly formed vertical dimension was verified during 8 week follow-up period. Within the information of interim prostheses, final restoration was constructed and delivered. The patient showed sound occlusal scheme and esthetic profile.

구치부 교합지지 상실과 비정상적 악간 관계는 교합 부조화로 이어지며 다양한 병적 징후를 동반한다. 저작, 심미 및 발음 기능을 회복하기 위해 교합고경과 교합평면 재설정에 따른 완전구강회복이 필요하게 된다. 본 증례는 75세의 여성으로 교합지지 상실과 불균일한 교합평면 및 II 급 부정교합을 가지고 있었다. 안모를 관찰하고 악간관계를 평가한 결과 상하악의 최대교두간접촉위가 상실되면서 수직교합고경이 감소된 것으로 진단되었다. 상악 국소의치와 하악 고정성보철물로 상실된 교합수직고경을 회복하고 조화로운 교합평면을 형성하였다. 수직고경 거상량은 7.5 mm로 하였고, 임시보철물을 이용하여 8 주간 경과 관찰 후 최종 보철물을 제작하였으며 저작효율과 심미성은 개선되었다.
