초록

치아의 마모는 노화로 인한 정상적인 과정이지만, 과도한 마모는 치아 구조물 상실, 치아민감성 증가, 치수 합병증 등 여러 합병증을 야기한다. 과도한 치아 마모 환자의 치료는 수직교합고경 상실 여부의 평가가 우선되어야 하는데, 보철수복공간이 부족할 경우 수직교합고경 증가가 필요할 수 있고, 종합적인 분석을 통해 치료계획을 수립하고 최소한의 증가량을 결정해야 한다. 본 증례는 66세 남환으로 심한 치아의 마모로 인한 저작기능 회복 및 심미적인 회복을 위해 내원하였다. 구강 검사, 방사선 검사, 진단 모형 검사 등을 통해 수직교합고경을 평가하고, 최소한의 수직교합고경 증가를 동반한 보철수복을 계획하였다. 8개월 간의 관찰 결과 중심위에서 치아의 균일한 접촉, 적절한 전방 및 측방 유도를 부여하였고, 환자의 기능적 문제를 해결하고 심미적 요구사항을 만족시킬 수 있었기에 이를 보고하는 바이다.

Although tooth wear is a normal process due to aging, severe tooth wear causes various complications such as increased tooth sensitivity, loss of tooth structure, and pulp complications. In the treatment of patients with excessive tooth wear, the evaluation of loss of vertical occlusal dimension should be prioritized. If it is necessary to increase the vertical dimension to secure the restoration space, it is important to establish a treatment plan with the comprehensive analysis and determine the minimum vertical dimension elevation. In this case, 66-year-old male patient with severe worn dentition wanted to restore masticatory function and improve esthetic restoration. In order to determine the appropriate vertical dimension of the patient, we evaluated oral examination, radiographic examination, and diagnostic cast examination, and performed rehabilitation with minimum vertical dimension elevation. As a result of observation for 8 months, the definitive prosthesis was completed with contact of all teeth in centric occlusion, and proper anterior/posterior guidance. Through the above process, satisfactory aesthetic and functional outcomes were obtained.
