The posterior mandibular region is an area limited by anatomic constraints. The use of resorbable membranes with a cortical component could compensate for the lack of rigidity of resorbable membranes without the complications of non-resorbable membranes. The aim of this study was to evaluate the mean bone gains of a xenogeneic cortical membrane in horizontal and vertical bone defects in comparison with other membranes in the literature. Methods: A porcine cortical membrane was used to perform 7 GBR in the posterior mandibular region of five patients. Preoperative (T0) and six months postoperative (T1) cone beam computed tomography were superimposed to measure the horizontal and vertical bone gain. Implants were positioned at all sites, six months after GBR. Complications and bone resorption around the implants were also documented. Results: The mean horizontal and vertical bone gains were 3.83 \u00b1 1.41 mm and 4.17 \u00b1 1.86 mm, respectively. The analysis of repeatability was 0.997. As many as 40% of patients experienced pain refractory to analgesics. No exposure or infectious phenomenon was observed. Conclusions: This xenogeneic cortical membrane seemed to provide interesting results in the regeneration of horizontal and vertical bone defects. Comparative and prospective studies are necessary to validate the effectiveness of this membrane.<\/jats:p>","DOI":"10.3390\/jcm13154575","type":"journal-article","created":{"date-parts":[[2024,8,5]],"date-time":"2024-08-05T13:57:28Z","timestamp":1722866248000},"page":"4575","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":5,"title":["Utilization of a Cortical Xenogeneic Membrane for Guided Bone Regeneration: A Retrospective Case Series"],"prefix":"10.3390","volume":"13","author":[{"ORCID":"https:\/\/orcid.org\/0000-0002-9230-7485","authenticated-orcid":false,"given":"Cyril","family":"Debortoli","sequence":"first","affiliation":[{"name":"Oral Surgery Department, Assistance Publique des H\u00f4pitaux de Marseille, 264 Avenue St Pierre, 13005 Marseille, France"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-6086-3217","authenticated-orcid":false,"given":"Arthur","family":"Falguiere","sequence":"additional","affiliation":[{"name":"Oral Surgery Department, Assistance Publique des H\u00f4pitaux de Marseille, 264 Avenue St Pierre, 13005 Marseille, France"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0003-1007-310X","authenticated-orcid":false,"given":"Fabrice","family":"Campana","sequence":"additional","affiliation":[{"name":"Oral Surgery Department, Assistance Publique des H\u00f4pitaux de Marseille, 264 Avenue St Pierre, 13005 Marseille, France"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-0015-4574","authenticated-orcid":false,"given":"Jean-Hugues","family":"Catherine","sequence":"additional","affiliation":[{"name":"Oral Surgery Department, Assistance Publique des H\u00f4pitaux de Marseille, 264 Avenue St Pierre, 13005 Marseille, France"},{"name":"Laboratory ISM, Aix-Marseille University, CNRS, EFS, 13005 Marseille, France"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Delphine","family":"Tardivo","sequence":"additional","affiliation":[{"name":"Laboratory ADES, Aix-Marseille University, CNRS, EFS, 13005 Marseille, France"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-5612-880X","authenticated-orcid":false,"given":"Romain","family":"Lan","sequence":"additional","affiliation":[{"name":"Oral Surgery Department, Assistance Publique des H\u00f4pitaux de Marseille, 264 Avenue St Pierre, 13005 Marseille, France"},{"name":"Laboratory ADES, Aix-Marseille University, CNRS, EFS, 13005 Marseille, France"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"1968","published-online":{"date-parts":[[2024,8,5]]},"reference":[{"key":"ref_1","doi-asserted-by":"crossref","first-page":"315","DOI":"10.1111\/eos.12364","article-title":"Guided bone regeneration: Materials and biological mechanisms revisited","volume":"125","author":"Elgali","year":"2017","journal-title":"Eur.
