Patients underwent single-tooth extraction in the posterior mandible. Fresh extraction sockets were filled with pre-hydrated cortico-cancellous porcine bone or collagen sponge. Two or 3 months later, a ridge expansion technique with immediate implant positioning placement was performed. Primary (alveolar width changes) and secondary outcomes (adverse events and long-term maintenance of buccal plate covering the implant) were evaluated.<\/jats:p>\n              <\/jats:sec><jats:sec>\n                <jats:title>Results<\/jats:title>\n                <jats:p>Thirty-four women and 20 men were selected: 30 implants (group A) placed into healed post-extraction sockets grafted with porcine bone and 24 (group B) into sockets filled with a collagen sponge. There was a significant loss in width in both groups from the first and second surgery (ranging between 2.7 mm and 4.5 mm). The ridge splitting with bone expansion resulted in significant long-term increases in width for both procedures and implant sites. Non-significant differences in alveolar width were registered between the groups at 10-year follow-up even if the analysis of the implant buccal bone coverage suggested that group A had significantly worst results.<\/jats:p>\n              <\/jats:sec><jats:sec>\n                <jats:title>Conclusions<\/jats:title>\n                <jats:p>Porcine bone group had significantly better short-term outcomes with lower long-term maintenance of the buccal plate.<\/jats:p>\n              <\/jats:sec>","DOI":"10.1186\/s40729-021-00354-7","type":"journal-article","created":{"date-parts":[[2021,7,28]],"date-time":"2021-07-28T23:06:14Z","timestamp":1627513574000},"update-policy":"https:\/\/doi.org\/10.1007\/springer_crossmark_policy","source":"Crossref","is-referenced-by-count":13,"title":["Bone remodeling around implants placed after socket preservation: a 10-year retrospective radiological study"],"prefix":"10.1186","volume":"7","author":[{"given":"Crespi","family":"Roberto","sequence":"first","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Toti","family":"Paolo","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Crespi","family":"Giovanni","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Covani","family":"Ugo","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Brevi","family":"Bruno","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Menchini-Fabris","family":"Giovanni-Battista","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"297","published-online":{"date-parts":[[2021,7,29]]},"reference":[{"issue":"2","key":"354_CR1","doi-asserted-by":"publisher","first-page":"212","DOI":"10.1111\/j.1600-051X.2005.00642.x","volume":"32","author":"MG Araujo","year":"2005","unstructured":"Araujo MG, Lindhe J.
