초록

치아 마모는 다양한 생리적, 병리적인 원인으로 일어나는 치아 경조직의 상실을 의미하며, 과도한 병적 마모는 치수의 병적 변화, 교합 부조화, 저작 기능 상실 및 심미적 문제 등의 합병증을 유발할 수 있다. 이러한 마모의 원인에 대해서는 교모, 마모, 부식, 굴곡파절에 의해 유발될 수 있으며 구강 내 교합하는 환경에서는 복합적으로 작용함이 알려져 있다. 과도한 병적 마모를 가진 환자의 경우 수복 전 수직 고경의 감소 유무에 대한 판단이 중요하며, 정확한 진단 및 분석과 예지성 있는 치료 계획 수립을 통해 근신경계와 악관절의 안정과 적응을 동반한 완전구강회복이 이루어져야 한다. 본 증례의 환자는 63세 남환으로 치아들이 많이 닳아 있으며 전반적으로 시리다는 주소로 본원에 내원하였으며, 환자의 교합수직고경에 관한 면밀한 분석 이후 교합수직고경의 증가를 동반한 완전구강회복을 시행하였다. 전체 치아의 균등한 접촉, 기능적 악운동과 조화를 이루는 전방 유도 및 측방 운동 시구치부 이개와 교합 평면의 개선을 치료 목표로 하였으며, 만족스러운 심미 및 기능적 결과를 얻었기에 이를 보고하고자 한다.

Tooth wear refers to the loss of dental hard tissue caused by various physiological and pathological causes, and excessive pathological wear can cause complications such as pathological changes in dimensions, occlusal disharmony, loss of function, and aesthetic problems. The cause of tooth wear can be caused by attrition, abrasion, corrosion and abfraction, and it is known to act in a multifactorial etiology in interocclusal activity. In patients with excessive pathological wear, it is important to determine whether or not the vertical dimension of occlusion is reduced, and complete oral rehabilitation should be achieved with the adaptation of the neuromuscular and temporomandibular joint through accurate diagnosis and analysis. The patient in this case was a 63-year-old male patient, who presented discomfort to cold beverage due to severe tooth wear. After analysis of the patient's vertical dimension of occlusion, a full mouth rehabilitation was performed with increasing vertical dimension of occlusion. The goal of treatment was to improve the occlusal plane with the equal-intensity contact of all teeth, harmonious anterior guidance and immediate disclusion of all posterior contacts. After rehabilitation, the patient was satisfied with function and esthetic appearance.
