Bone graft substitutes and dental implant stability in immediate implant surgery: a systematic review and meta-analysis.

Abstract

Implant dentistry is currently being revolutionized by breakthroughs in techniques, technology, and material, there are few systematic reviews and meta-analyses that examine the effects of utilizing different bone graft substitutes in immediate implant placement surgeries. The purpose of this research is to systematically review and meta-analyze the effect that different bone graft substitutes have on implant stability when concurrently utilized in patients undergoing immediate implant surgeries. The PICO criteria were used to construct the focused question, and the systematic review has been outlined as per the PRISMA guidelines. The revised Cochrane risk-of-bias method for randomized trials was used to assess the risk of bias for the selected articles. To derive estimates for the results, random effects meta-analysis was conducted on the selected articles. The electronic databases were searched and a total of 1583 articles were identified. After title and abstract screening and due to problems in retrieval a further 1358 articles were eliminated. Fifteen articles were finally chosen to be qualified for review. Of which full text evaluation of 5 articles were found to meet the eligibility criteria and were therefore included in the systematic review. This systematic review and meta-analysis on the stability of dental implants and bone graft substitutes in immediate implant surgery, was unable to draw any conclusions and established no statistically significant correlation between the different types of grafts used and implant stability.
