Abstract

Physiological wear of occlusal surface is inevitable throughout the lifetime, and considered to be normal. Pathologic wear, however, may cause fatal damage to the occlusal surface and destroy esthetics and proper anterior guidance. In such cases, rehabilitation of occlusal wear should be followed by thorough evaluation and diagnosis. In this present case, severe occlusal wear was found in the labial surfaces of mandibular anterior teeth and palatal surfaces of maxillary anterior teeth. Occlusal vertical dimension was evaluated and decided to be regained due to insufficient amount of restorative space. After determining new occlusal vertical dimension, diagnostic wax-up is usually performed to continue prosthodontic treatment. In this case with collapsed occlusion and loss of occlusal vertical dimension, conventional diagnostic wax-up was replaced with various digital devices. Diagnostic wax-up was digitally performed in the software and provisional prosthesis was fabricated with digital tools. With verification with provisional prosthesis, the entire dentition was rehabilitated with newly set occlusal vertical dimension and proper anterior guidance.

생리적 마모는 일생 동안 불가피하게 일어나고 정상현상이라고 볼 수 있다. 하지만, 병적인 마모는 교합면에 치명적 손상을 야기하고 심미 및 적절한 전방유도를 파괴 할 수 있다. 따라서 교합면 마모 회복을 위해서는 철저한 평가와 진단이 필요하다. 본 증례의 환자는 하악 치아 순면과 상악 치아 설면의 심한 마모를 보였다. 수직교합고경을 분석 하였고, 부족한 보철수복공간을 회복을 위해 수직교합고경을 높여서 치료하기로 하였다. 수직교합고경이 결정 된 후에는 보통 진단 왁스업을 하여 치료를 진행한다. 본 증례는 심한 마모로 인한 교합붕괴 및 수직교합고경이 상실된 환자에서, 기존의 진단왁스업 과정을 다양한 디지털 도구를 사용하는 방법으로 대체하였다. 진단왁스업은 소프트웨어에서 디자인되어 디지털로 임시보철물을 제작하였다. 임시보철물 검증을 통해, 수직교합고경 및 적절한 전방유도로 회복되었다.
