Methods: PubMed, Cochrane Central Register of Controlled Trials, and Ovid databases were searched for relevant studies published up to 16 September 2021. Randomized clinical trials (RCTs) and non-randomized controlled clinical trials (CCTs) that reported data on the new bone formation (measured by histomorphometric analysis) were considered. Risk of bias and quality assessment of included studies were evaluated following the Cochrane Handbook for Systematic Reviews of Interventions and the Risk Of Bias In Non-randomised Studies of Interventions (ROBINS-I) tool. Strength of evidence was assessed following the approach of the Agency for Healthcare Research and Quality (AHRQ) through its evidence-based practice center (AHRQ EPC). The meta-analysis was based on the primary outcome of newly formed bone, for which the standard mean difference was calculated. Results: After the application of eligibility criteria, six clinical trials (three RCTs and three CCTs) covering 85 maxillary sinus floor elevation procedures were included. The pooled new bone formation value for PRP was 1.67 (95% CI: \u22120.15 to 3.49; I2: 86%), indicating the absence of significant effect. Plasma rich in growth factors (PRGF) was the pure PRP tested in five of the included studies. When sub-group (type of PRP) meta-analysis was performed, significantly higher new bone formation was observed in the PRGF group [2.85 (95% CI: 0.07 to 5.64; I2: 88%)] in comparison to the control group. Conclusions: A beneficial effect on new bone formation after maxillary sinus floor elevation can be obtained when anorganic bovine bone is mixed with PRGF.<\/jats:p>","DOI":"10.3390\/bioengineering9100597","type":"journal-article","created":{"date-parts":[[2022,10,23]],"date-time":"2022-10-23T20:43:50Z","timestamp":1666557830000},"page":"597","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":12,"title":["Bone-Regenerative Ability of Platelet-Rich Plasma Following Sinus Augmentation with Anorganic Bovine Bone: A Systematic Review with Meta-Analysis"],"prefix":"10.3390","volume":"9","author":[{"ORCID":"https:\/\/orcid.org\/0000-0002-8386-5303","authenticated-orcid":false,"given":"Eduardo","family":"Anitua","sequence":"first","affiliation":[{"name":"Regenerative Medicine Department, BTI Biotechnology Institute, 01005 Vitoria, Spain"},{"name":"Clinical Research, University Institute for Regenerative Medicine and Oral Implantology (UIRMI), 01005 Vitoria, Spain"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Mikel","family":"Allende","sequence":"additional","affiliation":[{"name":"Regenerative Medicine Department, BTI Biotechnology Institute, 01005 Vitoria, Spain"},{"name":"Clinical Research, University Institute for Regenerative Medicine and Oral Implantology (UIRMI), 01005 Vitoria, Spain"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Asier","family":"Eguia","sequence":"additional","affiliation":[{"name":"Clinical Research, University Institute for Regenerative Medicine and Oral Implantology (UIRMI), 01005 Vitoria, Spain"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0003-4422-4527","authenticated-orcid":false,"given":"Mohammad","family":"Alkhraisat","sequence":"additional","affiliation":[{"name":"Regenerative Medicine Department, BTI Biotechnology Institute, 01005 Vitoria, Spain"},{"name":"Clinical Research, University Institute for Regenerative Medicine and Oral Implantology (UIRMI), 01005 Vitoria, Spain"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"1968","published-online":{"date-parts":[[2022,10,21]]},"reference":[{"key":"ref_1","first-page":"247","article-title":"Long-Term Survival and Success of Oral Implants in the Treatment of Full and Partial Arches: A 7-Year Prospective Study with the ITI Dental Implant System","volume":"19","author":"Romeo","year":"2004","journal-title":"Int.
