초록

구강이라는 특수한 환경 속에서 치아는 평생을 거쳐 마모, 부식 등을 겪게 된다. 점진적이며 일정한 치아의 마모는 노화의 자연스러운 현상이나, 특정 요소에 의한 마모나 부식 등은 병적인 요소이며 교합면의 병리적 손상과 이에 따른 교합 부조화, 심미적 문제, 턱관절 장애 등을 야기할 수 있다. 본 증례는 26세의 젊은 여성 환자로 전반적인 치아의 마모와 부식이 동반된 상태였다. 디지털 안모 분석, 생리적 안정위, 전치부 치관 길이 평가 등을 통해 진단 납형을 제작하였다. 디지털 분석을 통해 치관연장술에 필요한 가이드를 제작하여 수술을 진행하였고 임시 보철물을 통하여 저작 기능 및 심미성을 회복하였다. 지르코니아 최종 보철로 수복하여 심미적, 기능적으로 만족할만한 결과를 얻었으므로 이 증례를 보고하고자 한다.

In the oral cavity, the teeth undergo wear and corrosion throughout their lives. Progressive and constant tooth wear is a natural phenomenon of aging, but wear and corrosion due to specific factors are pathological factors. It can cause pathological damage of the occlusal surface, aesthetic problems, dimensional loss and jaw joint disorders. This case is a 26-year-old female patient with general tooth abrasion and erosion on the entire dentition. Diagnostic wax-up was fabricated based on the information including digital facial analysis, physiological stabilization, and evaluation of anterior crown length. Through the digital analysis, the necessary guides for crown lengthening were prepared and the mastication function and esthetics were evaluated by using temporary crowns. Definitive prosthesis was fabricated with the zirconia restorations. The results were satisfactory when they were observed 3 months of follow-up.
