Abstract

Gradual teeth wear is normal physiological progress, severe tooth wear can causes dysfunction, occlusal plane disharmony and esthetic problems. If additional space is needed for prosthetic restoration due to severe attrition, full mouth rehabilitation with increase of occlusal vertical dimension may be considered. In this case, 72 year old male patient with severe worn dentition, irregular gingival zenith and deep anterior bite was treated by full mouth rehabilitation for regaining the space for restoration, improving relationship and esthetic of anterior teeth. Provisional restoration obtained by systemic analysis, diagnosis and re-evaluation for a sufficient time was replicated to final restorations through double scanning technique using monolithic zirconia blocks. Satisfactory functional and esthetic outcomes were obtained.

점진적으로 진행되는 치아의 생리적인 마모는 정상적 현상이지만, 과도한 병적 마모는 기능장애와 교합평면의 부조화 및 심미성의 상실을 야기한다. 과도한 치아마모로 인해 구치부 지지의 상실 및 보철수복의 공간이 부족한 경우 수직교합고경 증가를 동반한 전악 수복이 고려될 수 있다. 본 증례는 잔존치의 과도한 치아마모와 기울어진 치은정점, 전치부 과개교합을 보이는 환자에서 교합거상을 통해 교합고경을 회복하였으며 부족한 구치부 보철 수복공간을 확보하고, 전치부 심미성과 교합관계를 개선할 수 있는 수직교합거상을 동반한 전악수복을 시행하였다. 체계적인 분석과 진단을 통해 임시보철물을 제작하여 충분한 적응기간을 거쳤으며, 이중 스캔방식을 통하여 단일구조 지르코니아 블럭을 사용해 최종보철물로 이행하여 기능적이고 심미적인 구강회복 결과를 얻었기에 이를 보고하고자 한다.
