目的:评估牙槽脊分裂(ARS)技术对牙槽脊水平宽度和植入物存活率的影响。
方法:在六个电子数据库中进行电子搜索(Pubmed,Embase,Cochrane中央受控试验登记册,WebofScience,中国国家知识基础设施,和SIGLE)从2010年1月1日至2023年11月1日。两位作者进行了研究选择,数据提取,并独立研究质量(ROBINS-I和RoB2.0)。采用综合meta分析3.0进行Meta分析。
结果:24项纳入的研究是观察性的,1项研究为随机对照试验(RCT)。14项研究调查了水平牙槽脊的宽度,17检查了植入物的存活率。为了评估偏见的风险,9项研究存在高偏倚风险,16项研究存在中等偏倚风险.荟萃分析表明,合并的获得牙槽脊宽度为3.348mm(95CI:4.163mm,2.533mm),种植体存活率为98.1%(95CI:98.9%,96.9%)。七项研究显示了七种不同的并发症,包括暴露,感染,坏分裂,开裂,骨折,感觉异常和软组织收缩。
结论:最近的ARS技术似乎是一种有效的骨增强方法,具有足够的增加宽度和较高的植入物存活率。仍然需要进一步的长期和RCTs研究来提高研究质量。
结论:ARS技术可以产生足够的骨体积,植入物的存活率很高。因此,已提出ARS是一种可靠的水平骨增强技术,为狭窄的牙槽峰的植入创造了良好条件。
To evaluate the effects of the alveolar ridge split (ARS) technique on gained horizontal width of the alveolar ridge and implant survival rate.
Electronic searching was performed in six electronic databases (Pubmed, Embase, the Cochrane Central Register of Controlled Trials, Web of Science, China National Knowledge Infrastructure, and SIGLE) from January 1, 2010, to November 1, 2023. Two authors performed study selection, data extraction, and study qualities (ROBINS-I and RoB 2.0) independently. Meta-analysis was performed by Comprehensive meta-analysis 3.0.
24 included studies were observational, and 1 study was a randomized controlled trial (RCT). 14 studies investigated the gained width of the horizontal alveolar ridge, and 17 examined the implants\' survival rate. For assessment of risk of bias, nine studies were high risk of bias and 16 studies were moderate risk of bias. Meta-analysis demonstrated that the pooled gained alveolar ridge width was 3.348 mm (95%CI: 4.163 mm, 2.533 mm), and the implant survival rate was 98.1% (95%CI: 98.9%, 96.9%). Seven studies showed seven different complications including exposure, infection, bad split, dehiscence, fracture, paresthesia and soft tissue retraction.
Recent ARS technique seems to be an effective method of bone augmentation with enough gained width and a high implant survival rate. Further long-term and RCTs research remains needed to enhance the study quality.
The ARS technique could generate sufficient bone volume, and implants had a high-level survival rate. Therefore, ARS has been proposed to be a reliable horizontal bone augmentation technique that creates good conditions for the implantation of narrow alveolar crests.
