Abstract

From the point of view of oral rehabilitation, the treatment of extensive tooth wear requires a prosthetic approach. Physiological tooth wear is considered as a normal process and generally does not require treatment, but excessive tooth wear causes problems like inadequate occlusion and esthetics. Changes of occlusal vertical dimension should be made through accurate diagnosis and analysis. Also, the patient's adaptation to the changed occlusal vertical dimension should be assessed over time. This case was a 60-year-old male patient who complained of a decrease in chewing function and esthetics due to severe tooth wear. Full-mouth rehabilitation was performed with a tooth supported fixed prosthesis. An occlusal stabilization splint and provisional restoration were used to evaluate the adaptation to increased occlusal vertical dimension and induce a stable centric relation position. After that, monolithic zirconia prosthesis was delivered. We report this as a satisfactory functional recovery and esthetics.

구강의 교합 재건의 관점에서 광범위한 치아 마모의 치료는 보철학적인 접근이 필요하다. 생리적인 치아의 마모는 정상적인 과정으로 간주되어 일반적으로 치료가 필요하지 않으나 과도한 치아의 마모는 부적절하고 불안정한 교합상태, 심미성의 감소, 저작 기능의 저하 등의 문제를 발생시켜 보철적인 수복을 필요로 한다. 마모된 치아의 전악 구강 회복 시 수직 교합 고경의 변화는 정확한 진단 및 분석을 통하여 이루어져야 하고 변화된 수직 교합 고경에 대한 환자의 적응 여부를 일정기간 평가하여야 한다. 본 증례는 60세 남성 환자로 전체적인 치아의 심한 마모로 인해 저작 기능과 심미성의 감소를 주소로 내원하였으며 수직 교합 고경의 증가를 동반한 치아 지지 고정성 보철물로 전악 구강 수복을 시행하였다. 증가된 수직 교합 고경의 적응 여부를 평가하고 안정된 하악위를 유도하기 위해 교합안정장치를 사용하였고, 임시 보철물을 사용하여 증가된 수직 교합 고경과 교합상태에 대한 적응을 평가하였다. 이후 단일구조 지르코니아 보철물을 제작하여 최종 접착하였고, 만족스러운 기능의 회복과 심미성을 보였기에 보고하는 바이다.
