摘要
牙列缺失后,常存在颌位关系异常,同时口腔黏膜组织萎缩变薄,敏感度增加,义齿难以获得良好的固位及咀嚼功能。种植修复能够降低骨吸收量,增加义齿稳定性,减少戴牙后疼痛,是恢复患者咀嚼功能的有效方法。但患者个体差异导致的咬合力大小,颌间距离,牙槽骨高度、宽度及质量,黏膜厚度等条件均有差异,不同医师提出的治疗方案各异,难以统一。本文拟就无牙颌种植修复常见问题及设计时应考虑的因素作以讨论。
The use of endosseous implants for complete dental restoration has gained popularity in the past few decades, with reliable long-term stability. Although most studies of the outcomes of prosthodontic rehabilitation with implantsupported dentures have focused on the evaluation of clinical anti technical aspects, still several factors involving the design of restoration anti surgery are remained debatable. This article will focus on these doubtful points and try to find out an ac.cepted solution based on previous researches.
