초록
일생에 걸친 치아의 생리적 마모는 자연스러운 과정으로 여겨지고 있지만 치아 마모가 교합수직고경의 감소, 저작 시 통증 및 저작 기능 상실, 심미성 소실 등의 병적 변화를 일으킨다고 판단되는 경우 치과의사가 이를 회복시켜주어야 한다. 본 증례 환자는 ‘아래 앞니가 입천장에 닿아서 아프다’는 주소로 내원하였다. 상악의 부적절한 보철물에 의한 하악 치열의 의원성 마모와 그에 따른 외상성 교합이 발생한 것으로 진단하였다. 진단모형 분석 및 납형조각을 통해 수직고경 거상을 결정하였으며 상악 및 하악을 적절한 고정성 보철물로 재수복하여 심미적 및 기능적으로 만족스러운 결과를 얻었기에 이를 보고하고자 한다.
Abstract
Physiologic tooth attrition is accepted as a natural change. But when pathologic changes, such as loss of occlusal vertical dimension, masticatory pain, loss of masticatory function, and loss of esthetics occur, restorative measures shouldbe taken by dentist. A patient visited the clinic with the chief complaint of ‘My lower teeth bite the palate and it hurts’. It was diagnosed as iatrogenic attrition of lower natural dentition caused by inappropriate upper restorations, resulting in traumatic overbite. Through model analysis and diagnostic wax up, increase in vertical dimension was decided. Upper and lower dentitions were restored with new prostheses. After restoration, satisfactory outcomes were achieved both in functional and esthetic aspects.
