엇갈린 교합을 가진 부분무치악 환자는 의치의 지지, 유지, 안정이 불량하고 회전으로 인한 잔존 지대치의 예후도 불량하다. 이 경우 적절한 수평 및 수직 악간관계를 설정하고 안정적인 교합평면과 교합접촉을 형성하기 위해 이중관 국소의치를 이용하면 수복공간 확보 및 기능적, 심미적인 치료 결과를 얻을 수 있다. 본 증례는 하악 전돌과 습관성 폐구위에서 대합되는 치아가 없어 전후방 엇갈린 교합을 가진 환자에서 이중관 국소의치를 이용하여 구강회복을 시행하였다. 모형 분석과 디지털 진단을 시행 후 임시보철물 형태의 템플릿을 제작하여 직관적이고 적절한 수직고경의 설정 및 안모평가를 시행하였고, 치료 및 기공 과정에 반영하여 제작한 최종 보철물로 적절한 기능과 심미를 회복할 수 있었기에 이를 보고하는 바이다.
Abstract
Partially edentulous patients with a crossed occlusion have poor denture support, retention, and stability. Moreover, residual abutments showed a poor prognosis due to denture rotation. The use of a conical double crown removable partial denture to establish proper horizontal and vertical interocclusal relationships, it can establish a stable occlusal plane and occlusal contacts providing a sufficient restorative space and a favorable functional and aesthetic outcome. In this case, a patient with an anteriorposterior crossed occlusion with mandibular prognathism and no occluding teeth in habitual centric position was treated with a conical double crown removable partial denture. After diagnostic cast analysis and digital diagnosis, provisional prosthesis templates were fabricated. It was possible to intuitive and appropriate vertical dimension determination and esthetic evaluation were performed. Definitive prosthesis with proper function and aesthetics can be fabricated by the digital and conventional treatment process.
