초록

구순구개열의 존재로 인한 음식물 비강이동, 상악 열성장에 의한 교차교합, 발음, 심미 문제를 해결하기 위해서 상악 구개열 근처 잔존치를 이중관으로 수복하고 구치부위는 구강형성(mouth preparation)을 이용한 고리 유지형 국소의치를 연합하여 사용하였다. 구개열로 인한 점막 지지의 소실을 이중관으로 보충해 줄 수 있고, 지대치의 발치시 수리가 쉬운 장점도 있다. 본 증례는 상악에 몇 개의 남은 치아와 구순구개열을 가진 55세 여자 환자에서 이중관과 고리 유지형 국소의치를 동시에 사용하여 구강비강 결손을 수복한 경우로 이중관과 고리 유지형 국소의치를 연합하여 사용하였다. 그 결과 구순구개열 환자에서의 구강비강연결을 차단할 수 있고, 교차교합을 용이하게 수정할 수 있었다. 또한 이중관 지대치의 이용과 구치부의 고리 유지형 국소의치를 이용하여 환자의 심미와 발음을 개선할 수 있었다.

Patients with cleft lip and palate have several problems such as oro-nasal communication, dental cross-bite caused by the insufficient growth of maxilla, poor pronunciation and esthetic problem. Removable denture with maxillary double crown near cleft palate and with clasp in the posterior teeth was used to solve the problems of the patient with cleft lip and plate. Double crowns make up for the insufficient mucosal support caused by the mucosa and alveolar bone loss in cleft lip and palate. Double crowns also allow easy repair of denture in case of abutment teeth extraction. In this case, 55-year-old female patient had bilateral cleft lip and palate and few remaining teeth on anterior maxilla. Prosthetic treatment was done for patient with bilateral cleft lip and palate to close oro-nasal communication using maxillary double crown and clasp retained removable denture. As a result, oro-nasal communication was effectively closed and the cross-bite was easily corrected by double crown and clasp retained denture. In addition, pronunciation and appearance were also improved.
