近年来，种植覆盖义齿在下颌无牙颌的修复中取得了良好的效果。然而，尚未评价对拮抗性颌骨吸收的影响。本研究的目的是在曲面断层片上检查三组不同下颌骨修复重建患者的前、后牙槽骨吸收情况：（1）由两个种植体支持的覆盖义齿，（2）由四到六个种植体支持的固定义齿，和（3）全口义齿。结果表明，与种植覆盖义齿患者相比，全口义齿患者的年骨吸收更明显。种植体支持的覆盖义齿患者观察到有限但持续的骨吸收，种植体支持的固定修复体组的年骨吸收略高。
For several years, implant-supported overdentures have been used with excellent results in rehabilitation of the edentulous mandible. The eff ect on the antagonistic jaw bone resorption however, has not yet been evaluated. The aim of this study was to examine on orthopantomograms the anterior and posterior maxillary ridge resorption in three groups of patients with different mandibular prosthetic reconstructions: (1) overdentures supported by two implants, (2) fixed prostheses supported by four to six implants, and (3) complete dentures. The results indicated a more pronounced annual bone resorption in complete denture wearers compared to patients with implant-supported overdentures. A limited but continuing bone resorption was observed for the patients with implant-supported overdentures, and a slightly higher annual bone resorption occurred in the implant-supported fixed prosthesis group.
