Abstract

Excessive tooth wear results in unacceptable damage to the occlusal surface and can cause pulpitis, occlusal disharmony, dysfunction, and unesthetic result. Patients with severe attrition have to be classified as several types relative to the vertical dimension of occlusion (VDO) and the interocclusal distance for the prosthetic space. The patient in this case was a 80 - year - old woman who lost support of posterior occlusion and collapsed of the occlusal plane due to confrontation of the opposing teeth, accompanied by an increase in the number of remaining bristles, resulting in a loss of intermaxillary space for prosthesis. In this case, treatment with increased vertical dimension may have stability if the increase in vertical occlusal height is minimized within the required range, and a stable occlusal contact is provided after an increased vertical occlusal height stabilization period. After the new VDO had been confirmed under interim fixed restorations, definitive fixed restorations were produced. Through these treatment processes, we obtain satisfactory results that are functional and aesthetically pleasing.

과도한 치아 마모를 가진 환자들을 치료를 시작할 때 수직교합고경의 상실과 수복을 위한 공간의 적절성으로 분류하게 된다. 본 증례의 환자는 80세의 여성으로 구치부 교합지지가 상실되어 대합치가 정출하면서 교합평면의 붕괴가 일어나고 잔존 치아의 마모 증가가 동반되어 보철을 위한 약간의 악간 공간의 상실이 발생하였다. 이러한 경우 최소한의 수직교합고경의 증가를 부여하고 안정화기간을 거쳐 안정된 교합접촉을 제공한다면 성공적으로 치료할 수 있다. 본 증례에서는 수직고경의 증가를 동반하여 단일 구조 지르코니아를 이용한 고정성 보철물과 상악 가철성 국소의치로 수복을 하였고 이러한 치료과정을 통하여 기능적, 심미적으로 만족스러운 결과를 얻어 보고하는 바이다.
