背景和目的骨增量程序，使牙科种植体的位置经常进行。该工作组的职责是评估目前关于牙槽嵴缺损重建再生措施有效性的证据。材料和方法讨论基于四项系统性综述，重点关注后期植入种植体的侧向骨增量、垂直骨增量、种植体周围炎相关缺损的重建治疗以及侧窗鼻窦增量手术的长期结果。结果大量证据支持种植体植入前的外侧骨增量是一种可预测的手术，以获得足够的种植体植入宽度。此外，许多研究表明，垂直牙槽嵴增高术可有效治疗牙槽嵴缺损，以允许种植牙。然而，两种手术的相关并发症发生率均较高。仅在少数RCT中评估了重建措施治疗种植体周围炎相关骨缺损的持续受益。荟萃分析证实了影像学骨增量方面的获益，但临床结局方面无获益。侧窗上颌窦底提升术被证明是一个可靠的程序，在长期的部分和完全无牙上颌骨。结论所评价的骨增量术是一种有效的牙槽嵴缺损修复方法。然而，有些手术要求很高，术后并发症的风险较高。
Background and Aims Bone augmentation procedures to enable dental implant placement are frequently performed. The remit of this working group was to evaluate the current evidence on the efficacy of regenerative measures for the reconstruction of alveolar ridge defects. Material and Methods The discussions were based on four systematic reviews focusing on lateral bone augmentation with implant placement at a later stage, vertical bone augmentation, reconstructive treatment of peri-implantitis associated defects, and long-term results of lateral window sinus augmentation procedures. Results A substantial body of evidence supports lateral bone augmentation prior to implant placement as a predictable procedure in order to gain sufficient ridge width for implant placement. Also, vertical ridge augmentation procedures were in many studies shown to be effective in treating deficient alveolar ridges to allow for dental implant placement. However, for both procedures the rate of associated complications was high. The adjunctive benefit of reconstructive measures for the treatment of peri-implantitis-related bone defects has only been assessed in a few RCTs. Meta-analyses demonstrated a benefit with regard to radiographic bone gain but not for clinical outcomes. Lateral window sinus floor augmentation was shown to be a reliable procedure in the long term for the partially and fully edentulous maxilla. Conclusions The evaluated bone augmentation procedures were proven to be effective for the reconstruction of alveolar ridge defects. However, some procedures are demanding and bear a higher risk for post-operative complications.
