Clinical efficacy of A-PRF on alveolar ridge preservation:A meta analysis
Objective:To evaluate the clinical efficacy of A-PRF in the preservation of alveolar ridge after tooth extraction.Methods:Electronic databases of VIP,CNKI,Wanfang,CQVIP,Medline,Pubmed and Cochrane library were searched.The meta-analysis was performed by using Revman 5.4.Results:5 RCTs including 217 patients were identified.A-PRF can significantly reduce the vertical bone absorption of the extraction socket,can increase the amount of new bone formation in the extraction socket(P＜0.05).However,A-PRF can not effectively reduce the horizontal bone absorption and can not improve the bone density in the extraction socket(P＞0.05).Conclusion:A-PRF is effective in the alveolar ridge preservation after tooth extraction.
