Abstract

The gradual teeth wear with age is a natural phenomenon, but excessive wear beyond physiological levels can lead to vertical dimension loss, occlusal imbalance, temporomandibular joint disorders, and periodontal disease. In such cases, prosthodontic restoration becomes necessary emphasizing the importance of appropriate vertical dimension increase and stable occlusion in central relation (CR). In this case, a 74-year-old patient with clenching and grinding habit had severe teeth wear and after assessing interocclusal distance, wear degree, pronunciation, and facial profile, it was decided to perform full-mouth fixed prosthesis restoration with a 4 mm vertical dimension increase. And the significantly displaced Maximum Intercuspal Position (MICP) caused by parafunctional movements was re-established as a stable mutually protective occlusal relationship at centric relation and after a successful 4 months adaptation to provisional restorations, the final prosthesis was fabricated. During 4months of observation periods, stable occlusion in central relation and mutual protection occlusal relationships were maintained and the patient was satisfied with function and aesthetics, leading to this report.

연령 증가에 따른 치아의 점진적인 마모는 자연적인 현상이나 생리적인 정도를 넘어 과도하게 발생하게 되면 수직 고경 상실, 교합 부조화, 악관절 질환, 치수병변 등을 일으킬 수 있어 보철물 수복이 필요하며, 이 때 적절한 수직 고경 거상과 함께 중심위(Centric Relation, CR)에서의 안정적인 교합 설정이 중요하다. 본 증례는 이 악물기와 이갈이 습관이 있는 74세 남환이 과도한 치아 마모를 주소로 내원하였고 이에 악간 거리, 마모 정도, 발음, 안모 평가 등을 시행한 결과 4 mm 수직 고경 거상을 동반한 전악 고정성 보철 수복을 진행하기로 하였다. 또한 비기능 하악 운동으로 인해 반복 재현성이 크게 떨어진 최대교두간 접촉위(Maximum Intercuspal Position, MICP)를 중심위에서의 안정적인 교합과 전‧측방 유도 시 상호보호교합이 되도록 적절히 형성해 주었다. 4개월간 임시 수복물에 적응한 것을 확인한 후 최종 보철물을 제작하였고 이후 4개월간 관찰한 결과 기능 및 심미적으로 결과를 만족하였기에 이를 보고하고자 한다.
