摘要

Severe worn dentition is frequently multifactorial and making rehabilitation quite challenging. Since extensive tooth wear usually resulted in loss of anterior guidance and aggravated posterior tooth wear, such condition may compromise occlusal plane and occlusal vertical dimension (OVD). This case report presents a 67-year-old male losing multiple teeth and having severe worn dentition and fixed and removable interim restorations were used to re-establish the occlusal plane and occlusal vertical dimension (OVD). After the trial period, the patient was adapted well to his interim prostheses, which were adopted as the guide for definite restoration. The aim of the report is to show treating severe worn dentition with conventional prostheses and reviewing relevant literatures.

嚴重齒質磨耗經常是多因性的發生，臨床上除了詳細問診瞭解病史與生活飲食習慣，並且觀察患者口腔磨耗外觀與追蹤磨耗進程，藉此評估分析疾病可能成因與做出正確的診斷，之後治療計畫的擬定方可對症下藥。嚴重磨耗的齒列往往會造成前牙導引喪失進而發生後牙咬合干擾與進一步磨耗，如此循環會惡化磨耗程度，咬合高度改變與咬合平面傾斜等等，使得治療更複雜必須跨科配合。此篇病例報告描述藉由固定與活動之臨時假牙重建咬合平面與咬合高度，待患者適應之後利用傳統固定牙冠牙橋與活動假牙進行全口重建，並回顧探討相關文獻。
