구순구개열 환자에게 가철성 보철치료는 중요한 치료 선택 중 하나이다. 구순구개열 환자에서 만족스러운 기능적 및 심미적 결과를 얻기 위해서는 전통적인 보철 치료법에서 약간의 수정이 필요할 수 있는데, 치주 질환에 이환되어 있으며 소수의 구치만 잔존해 있는 구개열 환자의 경우 이중관에 연결된 가철성 보철이 치료 선택의 대안이 될 수 있다. 이중관이 가철성 국소의치에 연결되면 보철적 안정성과 유지를 증가시키고 치아 장축에 유리한 힘 전달을 최적화하며 심미성도 향상시킨다. 그리고 이중관 의치의 횡단치열궁안정(cross arch stabilization)은 구순구개열 환자의 갈라진 치조제의 안정화에도 도움을 준다. 본 증례는 성인 구순구개열 환자에서 마찰핀(friction pin)을 사용한 혼성 이중관 가철성 국소의치를 제작하여 유지 및 안정성과 함께 심미성도 향상시켜 만족할 만한 결과를 나타낸다.
Abstract
For individuals with cleft lip and palate, the removable partial dentures (RPDs) have been an important treatment option. Some modifications from conventional prosthetic treatment may be necessary to achieve satisfactory functional and esthetic results in cleft patients. In case of cleft palate patient with periodontally compromised and only posterior few remaining teeth, removable partial prosthesis connected to telescopic crown can be the alternative treatment option. When connected to the RPD, telescopic crowns increase the prosthetic stability and retention, optimize favorable force transmission to the long dental axis, and improve esthetics. And the cross arch stabilization of double crown denture helps to stabilize both divided maxillary ridges in CLP patient. This case present one adult CLP patient using an RPD connected with hybrid telescopic crowns with friction pins to improve not only retention and stability but also aesthetics.
