一种治疗方案，可能会导致减少下颌后残留牙槽骨吸收的患者覆盖义齿保留和支持两个椎间孔种植体进行了调查。治疗包括在后牙列无牙下颌骨中添加短种植体，以向牙槽骨提供有利的机械负荷刺激。三维有限元分析被用来模拟引用的有效应变，可能会刺激骨重建在两个选定的模型。基于这项实验室研究，增加后短种植体在保持种植体固位覆盖义齿下的骨量方面具有良好的效果。
A treatment protocol that may lead to reduced mandibular posterior residual ridge resorption in patients with overdentures retained and supported by two interforaminal implants was investigated. The treatment included the addition of short implants in the posterior edentulous mandible for the presumed purpose of favorable provision of mechanical load stimulus to alveolar bone. Three-dimensional finite element analysis was used to model cited effective strains that may stimulate bone remodeling in two selected models. Based on this laboratory study, the addition of posterior short implants has a favorable effect in maintaining bone mass under implant-retained overdentures.
