This study has shown that treatment with distally extending cantilever fixed partial dentures is a favorable alternative to treatment with removable partial dentures in elderly patients with reduced dentition. In patients with anterior teeth and one or two premolar teeth remaining in the mandible, sufficient occlusal stabilization for a maxillary complete denture was provided by a two- or three-unit cantilever fixed partial denture. A pronounced improvement in chewing function and stability of the maxillary denture was expressed, even by patients who were previously well adapted to wearing removable partial dentures.
本研究表明,对于牙列减少的老年患者,使用远中延伸悬臂式固定局部义齿进行治疗是一种优于可摘局部义齿治疗的选择。在下颌仅余留前牙及一或两颗前磨牙的患者中,两单位或三单位悬臂式固定局部义齿可为上颌全口义齿提供足够的咬合稳定性。即使是之前已很好适应佩戴可摘局部义齿的患者,其咀嚼功能及上颌义齿稳定性也有显著改善。
