Abstract

The progressive attrition of teeth is a normal process by aging. However, excessive tooth wear with decreased vertical dimension of occlusion and collapse of occlusal plane may cause pathologic pulpal condition, occlusal disharmony and functional disorders. In this case, a patient with severely worn dentition was treated. Diagnostic wax-up was performed at the increased vertical dimension. After evaluation of provisional restorations for 12 weeks, final restorations were fabricated with zirconia crown and routine clinical assessments were made. Esthetically and functionally satisfactory results were obtained.

점진적인 마모는 정상적인 과정이지만 교합면의 마모가 병적으로 과도하게 진행되어 교합평면이 붕괴된 경우 교합, 저작근, 치수병변 등의 문제가 나타날 수 있다. 본 증례에서는 광범위한 마모를 보이는 환자에서 수직고경을 증가하여 임시 수복물을 제작한 후 약 12주간 환자의 적응 여부와 심미성을 평가하였다. 임시 수복물을 바탕으로 CAD/CAM 단일구조 지르코니아를 이용해 전악 고정성 보철물로 수복 하였으며, 기능적인 면과 심미적인 면에서 만족스러운 결과를 얻었기에 이를 보고하는 바이다.
