Vertical Ridge Augmentation in the Atrophic Mandible: A Systematic Review and Meta-Analysis.

摘要: Purpose: To systematically appraise the effectiveness/reliability of vertical ridge augmentation (VRA) in atrophic mandible. Articles that addressed any one following four areas were included this study: amount VRA, implant survival (ISR) and success rates (SSR) area newly regenerated bone, complication rate during bone procedure, resorption. Materials Methods: An electronic literature search was conducted by two independent reviewers several databases, including MEDLINE, EMBASE, Cochrane Central Register Controlled Trials, Oral Health Group Trials databases for articles reporting VRA mandible via distraction osteogenesis (DO), inlay block grafting (IBG), onlay (OBG), guided regeneration (GBR). For meta-analysis, primary (VRA ISR [%]) secondary outcomes studied (SSR [%] resorption [VBR] [%}). Additionally, qualitative assessment, complications (ie, causes failure) further extracted comprehensively described. Results: Overall, 73 full-text papers evaluated. Of these, 52 fulfilled inclusion criteria. The weight mean (WM) (± SD) 4.49 ± 0.33 mm (95% CI: 3.85 to 5.14 mm). It most notable DO involved greater than IBG, thus, significantly higher GBR OBG. technique influenced obtained (P < .001). Nonetheless, no showed superiority terms or SSR. VBR shown be minimized GBR. Conclusion: If ~ 4 is needed, optimum local systemic conditions should equally reliable However, when IBG have demonstrated accuracy. By means rates, lowest. SSR, statistical differences existed among all techniques. studies are needed examine long-term peri-implant fate frequency biologic each applied atrophied
