Abstract

The aim of this study was to investigate the loss of teeth in positions mesially adjacent to implant-supported fixed dentures (IFDs) after insertion of IFDs in unilateral free-end edentulous spaces in the mandible at dental clinics. There were a total of 157 adjacent teeth. Nine adjacent teeth (5.73%, 9 of 157), 9 opposing teeth (2.59%, 9 of 348), 38 posterior teeth (1.93%, 38 of 1,964), and 3 anterior teeth (0.22%, 3 of 1,380) were lost during the observation period. The percentage of lost adjacent teeth was higher than that of posterior teeth (P = .002). Teeth in positions adjacent to the IFDs require more attention than other remaining teeth.

摘要

本研究的目的是调查在牙科诊所将种植体支持的固定义齿（IFD）植入下颌单侧游离端无牙间隙后，IFD近中相邻位置牙齿的缺失情况。共有157颗相邻牙齿。在观察期内，9颗相邻牙齿（5.73%，157颗中的9颗）、9颗对颌牙齿（2.59%，348颗中的9颗）、38颗后牙（1.93%，1964颗中的38颗）和3颗前牙（0.22%，1380颗中的3颗）缺失。相邻牙齿的缺失百分比高于后牙（P = 0.002）。与IFD相邻位置的牙齿比其他剩余牙齿需要更多关注。
