Twenty-six patients with 30 surgical sites who required two-stage MSA were enrolled and grafted with the combination of A-PRF and SACBAs. The surgical sites were randomly allocated to the test or control group. During implant site preparation, 17 bone core biopsy samples were collected from each study group for histological, histomorphometric and micromorphometric analysis. Resonance frequency analysis was performed at the time of implant placement and 6, 8, 10, and 12 weeks postoperatively. The percentage of newly formed bone was 44.89 \u00b1 9.49% in the test group and 39.75 \u00b1 8.15% in the control group (p = 0.100). The results of the \u00b5CT analysis showed no significant differences in morphometric parameters between the study groups. The implant stability quotient was not significantly different between the two groups at 10 and 12 weeks postoperatively. Based on these findings, the total treatment time may be reduced by 3 months with the use of A-PRF and SACBAs for two-stage MSA.<\/jats:p>","DOI":"10.3390\/ma14071810","type":"journal-article","created":{"date-parts":[[2021,4,6]],"date-time":"2021-04-06T10:34:12Z","timestamp":1617705252000},"page":"1810","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":19,"title":["Evaluation of the Histomorphometric and Micromorphometric Performance of a Serum Albumin-Coated Bone Allograft Combined with A-PRF for Early and Conventional Healing Protocols after Maxillary Sinus Augmentation: A Randomized Clinical Trial"],"prefix":"10.3390","volume":"14","author":[{"ORCID":"https:\/\/orcid.org\/0000-0003-2308-2312","authenticated-orcid":false,"given":"B\u00e1lint","family":"Trimmel","sequence":"first","affiliation":[{"name":"Department of Oral Diagnostics, Faculty of Dentistry, Semmelweis University, Szentkir\u00e1lyi utca 40, 1088 Budapest, Hungary"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Szabolcs","family":"Gyulai-Ga\u00e1l","sequence":"additional","affiliation":[{"name":"Department of Oral Diagnostics, Faculty of Dentistry, Semmelweis University, Szentkir\u00e1lyi utca 40, 1088 Budapest, Hungary"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0003-0728-7027","authenticated-orcid":false,"given":"M\u00e1rton","family":"Kivovics","sequence":"additional","affiliation":[{"name":"Department of Community Dentistry, Faculty of Dentistry, Semmelweis University, Szentkir\u00e1lyi utca 40, 1088 Budapest, Hungary"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"No\u00e9mi Piroska","family":"J\u00e1kob","sequence":"additional","affiliation":[{"name":"Department of Pathology and Experimental Cancer Research, Semmelweis University, \u00dcll\u0151i \u00fat 26, 1085 Budapest, Hungary"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0003-4143-2507","authenticated-orcid":false,"given":"Csaba","family":"Heged\u0171s","sequence":"additional","affiliation":[{"name":"Department of Biomaterials and Prosthetic Dentistry, Faculty of Dentistry, University of Debrecen, Egyetem t\u00e9r 1, H-4032 Debrecen, Hungary"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Bence Tam\u00e1s","family":"Szab\u00f3","sequence":"additional","affiliation":[{"name":"Department of Oral Diagnostics, Faculty of Dentistry, Semmelweis University, Szentkir\u00e1lyi utca 40, 1088 Budapest, Hungary"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0001-9530-7926","authenticated-orcid":false,"given":"Csaba","family":"Dob\u00f3-Nagy","sequence":"additional","affiliation":[{"name":"Department of Oral Diagnostics, Faculty of Dentistry, Semmelweis University, Szentkir\u00e1lyi utca 40, 1088 Budapest, Hungary"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Gy\u00f6rgy","family":"Szab\u00f3","sequence":"additional","affiliation":[{"name":"Department of Oro-Maxillofacial Surgery and Stomatology, Faculty of Dentistry, Semmelweis University, M\u00e1ria utca 52, 1085 Budapest, Hungary"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"1968","published-online":{"date-parts":[[2021,4,6]]},"reference":[{"key":"ref_1","doi-asserted-by":"crossref","first-page":"17","DOI":"10.5115\/acb.2019.52.1.17","article-title":"Clinical anatomy of the maxillary sinus: Application to sinus floor augmentation","volume":"52","author":"Iwanaga","year":"2019","journal-title":"Anat.
