Abstract

Reconstruction of the maxillectomy with an obturator is to restore masticatory, swallowing, phonetic and esthetic problems. Stress created by lateral forces is minimized by the proper selection of an occlusal scheme, elimination of premature occlusal contacts, and wide distribution of supporting area. It should be considered that properly designed retainers reduce the stresses transmitted to the abutment while the obturator is in function. The following clinical report presents palatal obturator treatment with implant assisted removable partial denture (IARPD) design that restores normal function and esthetics in patients who experienced maxillectomy and dental implant failure.

상악골 절제술을 받은 환자의 구개폐쇄장치 보철 수복은 구강과 비강 및 상악동의 개통으로 인한 저작기능, 연하, 발음 및 심미성의 상실을 회복하는 것을 목적으로 하는 치료이다. 상악골 절제술 환자에서 구개폐쇄장치 설계 시 측방력으로 인해 야기되는 응력은 적절한 교합 양식의 선택, 조기 교합접촉의 제거, 광범위한 지지영역의 활용으로 최소화될 수 있다. 또한 기능 시 응력이 지대치로 전달되는 것을 줄여주는 유지장치의 고안이 필요하다. 본 증례보고는 임플란트 실패를 경험한 상악골 절제술 환자에게 잔존 임플란트를 이용한 가철성 국소의치(implant assisted removable partial denture, IARPD) 형태의 구개폐쇄장치를 제작하여 기능과 심미성 회복을 이룬 보철수복을 보고하고자 한다.
