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.
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.
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.
讨论基于四项系统评价,重点是在后期植入植入的外侧骨增强。垂直骨增强,种植体周围炎相关缺陷的重建治疗,以及外侧窗窦增大术的长期结果。
大量证据支持在植入物放置之前进行侧向骨增强,这是一种可预测的程序,以获得足够的隆脊宽度用于植入物放置。此外,许多研究表明,垂直牙脊增强程序可有效治疗牙槽脊不足,从而可以放置牙种植体。然而,两种手术的相关并发症发生率均较高.仅在少数RCT中评估了重建措施对治疗种植体周围炎相关骨缺损的辅助益处。荟萃分析表明,在放射学骨增加方面有益处,但对临床结果没有益处。从长期来看,对于部分和完全无牙的上颌骨,外侧窗窦底增强术被证明是可靠的手术。
评估的骨增强程序被证明是有效的重建牙槽骨缺损。然而,有些手术要求很高,并且术后并发症的风险更高。
