Maxillary sinus grafting, typically using autogenous bone, is a common solution. However, autogenous bone grafts require additional surgical procedures, leading to increased morbidity. This study aims to compare the efficacy of two xenografts, Bio-Oss and Cerabone, in promoting new bone formation in maxillary sinus grafting through histomorphometric analysis and micro-computed tomography (micro-CT). Materials and Methods: A total of 22 maxillary sinuses (12 right and 10 left) were grafted, with 12 using Cerabone and 10 using Bio-Oss. Six months post-grafting, biopsies were collected for histomorphometric analysis to measure new bone formation, connective tissue, and residual biomaterial. Additionally, micro-CT analysis was performed to assess bone volume fraction, trabecular thickness, number, and separation. Results: Histomorphometric analysis showed that the Cerabone group had a higher average new bone formation (25.94% \u00b1 10.55) compared to the Bio-Oss group (17.29% \u00b1 4.61), with a statistically significant difference (p = 0.02). Micro-CT analysis revealed that the bone volume fraction in the Cerabone group was significantly higher compared to the Bio-Oss group, with significant differences in trabecular thickness (p = 0.02) but not in trabecular number or separation. Conclusions: The study demonstrates that both xenografts are effective in promoting new bone formation in maxillary sinus grafting. However, Cerabone showed superior performance in terms of new bone formation and bone volume fraction, suggesting it may be a more effective option for maxillary sinus augmentation procedures.<\/jats:p>","DOI":"10.3390\/medicina60111834","type":"journal-article","created":{"date-parts":[[2024,11,8]],"date-time":"2024-11-08T04:02:54Z","timestamp":1731038574000},"page":"1834","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":13,"title":["Histomorphometric and Micro-CT Evaluation of Cerabone and Bio-Oss in Maxillary Sinus Lifting: A Randomized Clinical Trial"],"prefix":"10.3390","volume":"60","author":[{"ORCID":"https:\/\/orcid.org\/0000-0003-2509-8633","authenticated-orcid":false,"given":"Rodrigo dos Santos","family":"Pereira","sequence":"first","affiliation":[{"name":"Department of Oral & Maxillofacial Surgery, University of Grande Rio\u2014UNIGRANRIO, Rio de Janeiro 25071-202, Brazil"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0003-1475-9459","authenticated-orcid":false,"given":"Marcus Vinicius Neumann Brand\u00e3o","family":"de Carvalho","sequence":"additional","affiliation":[{"name":"Department of Oral & Maxillofacial Surgery, University of Grande Rio\u2014UNIGRANRIO, Rio de Janeiro 25071-202, Brazil"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Eduardo","family":"Hochuli-Vieira","sequence":"additional","affiliation":[{"name":"Department of Diagnostic and Surgery, Araraquara School of Dentistry, Sao Paulo State University, Sao Paulo 14801-385, Brazil"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0001-7973-2455","authenticated-orcid":false,"given":"Cristian","family":"Statkievicz","sequence":"additional","affiliation":[{"name":"Department of Diagnostic and Surgery, Ara\u00e7atuba School of Dentistry, Sao Paulo State University, Sao Paulo 16066-840, Brazil"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0003-4577-6809","authenticated-orcid":false,"given":"D\u00e9borah Laurindo","family":"Pereira Santos","sequence":"additional","affiliation":[{"name":"Department of Oral Surgery, Maur\u00edcio de Nassau Dental School\u2013Uninassau, Macei\u00f3 57051-565, Brazil"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Renato Torres","family":"Augusto Neto","sequence":"additional","affiliation":[{"name":"School of Dentistry, Federal University of Alagoas\u2014UFAL, Macei\u00f3 57072-970, Brazil"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Carolina de F\u00e1tima Soares","family":"Pinto","sequence":"additional","affiliation":[{"name":"Department of Oral & Maxillofacial Surgery, University of Grande Rio\u2014UNIGRANRIO, Rio de Janeiro 25071-202, Brazil"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-6528-2681","authenticated-orcid":false,"given":"Francesco","family":"Bennardo","sequence":"additional","affiliation":[{"name":"School of Dentistry, Magna Graecia University of Catanzaro, Catanzaro 88100, Italy"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0001-5775-0222","authenticated-orcid":false,"given":"Carlos Fernando","family":"Mour\u00e3o","sequence":"additional","affiliation":[{"name":"Department of Basics and Clinical Translational Sciences, Tufts University School of Dental Medicine, Boston, MA 02111, USA"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"1968","published-online":{"date-parts":[[2024,11,8]]},"reference":[{"key":"ref_1","doi-asserted-by":"crossref","first-page":"1424","DOI":"10.1177\/0022034518792567","article-title":"Trends in Dental Implant Use in the U.S., 1999\u20132016, and Projections to 2026","volume":"97","author":"Elani","year":"2018","journal-title":"J.
