치아의 마모는 점진적으로 발생하는 생리적인 현상으로 알려져 있다. 생리적 마모는 그 정도가 적고 치조골의 보상성 성장과 치아의 정출에 의해 수직고경이 유지된다고 보고되고 있다. 하지만 과도한 병적마모는 병적인 치수상태, 교합부조화, 기능장애와 심미적인 문제를 야기하여 완전 구강 회복술을 요하는 경우가 많다. 수복 시에는 기능과 심미를 회복할 수 있는 적절한 수직고경의 변경이 필요하며 근신경계와 조화를 이루는 고경의 결정이 중요하다. 본 증례는 36세 여성으로, 전반적인 치아마모와 심미적 불만족을 주소로 내원하였다. 마모된 정도와 심미를 고려하여 상악 전치부 절단면 기준으로 감소한 수직고경을 2 mm 회복하고 완전도재관을 이용하여 수복하였다. 이에 적절한 심미적, 기능적 결과를 얻었기에 이를 보고하는 바이다.
Abstract
Tooth wear is known as a normal physiological process which gradually progresses. It is reported that vertical dimension can be kept stable because amount of physiologically worn loss could be compensated by growth of alveolar bone and tooth eruption. However, excessive tooth wear as pathologic wear can cause pathologic pulp, disharmony with occlusal plane, functional disorders and esthetic problems so that full mouth rehabilitation could be needed in these cases. Recovery of function and esthetic improvement should be considered for alteration of the vertical dimension. Determination of the vertical dimension of occlusion is needed to be in harmony with the neuromuscular system. This clinical report describes 36 year-old female patient who had chief complaint of severely worn dentition and esthetic discomfort. An increase of 2.0 mm at maxillary incisal edge was done to restore vertical dimension. It was based on the degree of tooth wear and esthetics.
