Effects of post-extraction alveolar ridge preservation versus immediate implant placement: a systematic review and meta-analysis
The journal of evidence-based dental practice(2022)
摘要
ObjectivesThis systematic review aimed to compare the clinical data including success rates, tissue preservation, esthetic results, and patient-reported outcomes between delayed implant placement after alveolar ridge preservation (ARP) and imme-diate implant placement (IIP).Material and methodsBoth electronic and manual searches were performed for randomized controlled trials and cohort studies consisting of at least 10 cases per group and a follow-up of at least 1-year in duration. The primary outcome was the implant success rate and secondary outcomes were changes in marginal bone level (MBL), pink esthetic score (PES) and patient reported outcomes consisting of complications and satisfaction.ResultsA total of 12 studies were included (8 randomized controlled trials and 4 cohort studies). This review contained 456 implants placed after ARP and 459 implants placed through IIP. The results from this meta-analysis showed that the success rates of implants placed through ARP protocol (98.68%) was significantly higher than that of implants placed through IIP protocol (95.21%) (RR = 1.03; 95% CI [1.01; 1.06]; P = .008; I 2 = 0%).ConclusionThe results from this meta-analysis and systematic review showed that implants placed through ARP protocol may demonstrate higher success rates compared to implants placed through IIP.
