The Biologically\u2010oriented Alveolar Ridge Preservation (BARP) concept and its modified application for compromised sockets (mBARP) were developed as innovative biologically driven protocols based on selective compartmentalized grafting. Instead of completely filling the socket, these approaches preserve spontaneous healing in the apical compartment while reinforcing the coronal portion, where dimensional changes are greatest. The protocols combine a collagen sponge in the apical part of the socket with xenograft particles and a collagen sponge sealing the coronal compartment. In compromised sockets, an additional collagen sponge is positioned between the residual buccal or lingual wall and the mucoperiosteal flap to enhance graft containment and soft tissue support. Thirty extraction sites were treated using this approach. After 4\u20136\u2009months, ridge dimensions were effectively preserved, with a slight vertical loss (+0.3\u2009mm), limited horizontal reduction (0.7\u20131.0\u2009mm), controlled buccal soft tissue contraction (2.0\u20132.2\u2009mm), and substantial new bone formation (38%\u201340%), while residual graft particles remained mainly confined to the coronal compartment. Within the limitations of this study, the BARP concept and its modified application demonstrated favorable clinical, radiographic, and histological outcomes, supporting selective coronal grafting as an innovative strategy to preserve ridge dimensions while maintaining physiological healing in the deeper portion of the extraction socket.<\/jats:p>","DOI":"10.1111\/jre.70153","type":"journal-article","created":{"date-parts":[[2026,7,18]],"date-time":"2026-07-18T09:16:53Z","timestamp":1784366213000},"update-policy":"https:\/\/doi.org\/10.1002\/crossmark_policy","source":"Crossref","is-referenced-by-count":0,"title":["Biologically\u2010Oriented Alveolar Ridge Preservation (\n                    <scp>BARP<\/scp>\n                    ) in Intact and Compromised Extraction Sockets"],"prefix":"10.1111","author":[{"ORCID":"https:\/\/orcid.org\/0000-0002-5448-6574","authenticated-orcid":false,"given":"Mattia","family":"Pramstraller","sequence":"first","affiliation":[{"name":"Research Centre for the Study of Periodontal and Peri\u2010Implant Diseases University of Ferrara  Ferrara Italy"},{"name":"Operative Unit of Dentistry Azienda Unit\u00e0 Sanitaria Locale (AUSL) of Ferrara  Ferrara Italy"},{"name":"Private Practice  Padova Italy"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-4621-7809","authenticated-orcid":false,"given":"Roberto","family":"Farina","sequence":"additional","affiliation":[{"name":"Research Centre for the Study of Periodontal and Peri\u2010Implant Diseases University of Ferrara  Ferrara Italy"},{"name":"Operative Unit of Dentistry Azienda Unit\u00e0 Sanitaria Locale (AUSL) of Ferrara  Ferrara Italy"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-9941-3491","authenticated-orcid":false,"given":"Anina Nives","family":"Zuercher","sequence":"additional","affiliation":[{"name":"Clinic of Reconstructive Dentistry, Center for Dental Medicine University of Zurich  Zurich Switzerland"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Ronald Ernst","family":"Jung","sequence":"additional","affiliation":[{"name":"Clinic of Reconstructive Dentistry, Center for Dental Medicine University of Zurich  Zurich Switzerland"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-3001-1347","authenticated-orcid":false,"given":"Mike","family":"Barbeck","sequence":"additional","affiliation":[{"name":"BerlinAnalytix GmbH  Berlin Germany"},{"name":"Clinic and Policlinic for Dermatology and Venereology University Medical Center Rostock  Rostock Germany"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0009-0008-5378-4212","authenticated-orcid":false,"given":"Marco","family":"Fracasso","sequence":"additional","affiliation":[{"name":"Research Centre for the Study of Periodontal and Peri\u2010Implant Diseases University of Ferrara  Ferrara Italy"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Alberto","family":"Sclip","sequence":"additional","affiliation":[{"name":"Research Centre for the Study of Periodontal and Peri\u2010Implant Diseases University of Ferrara  Ferrara Italy"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-1147-2199","authenticated-orcid":false,"given":"Leonardo","family":"Trombelli","sequence":"additional","affiliation":[{"name":"Research Centre for the Study of Periodontal and Peri\u2010Implant Diseases University of Ferrara  Ferrara Italy"},{"name":"Operative Unit of Dentistry Azienda Unit\u00e0 Sanitaria Locale (AUSL) of Ferrara  Ferrara Italy"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"311","published-online":{"date-parts":[[2026,7,18]]},"reference":[{"key":"e_1_2_15_2_1","doi-asserted-by":"crossref","first-page":"1048","DOI":"10.1111\/j.1600-051X.2009.01482.x","article-title":"Alveolar Bone Dimensional Changes of Post\u2010Extraction Sockets in Humans: A Systematic Review","volume":"36","author":"Van der Weijden F.","year":"2009","journal-title":"Journal of Clinical Periodontology"},{"key":"e_1_2_15_3_1","doi-asserted-by":"crossref","first-page":"630","DOI":"10.1111\/j.1600-051X.2008.01246.x","article-title":"Modeling and Remodeling of Human Extraction Sockets","volume":"35","author":"Trombelli L.","year":"2008","journal-title":"Journal of Clinical Periodontology"},{"issue":"5","key":"e_1_2_15_4_1","doi-asserted-by":"crossref","first-page":"1","DOI":"10.1111\/j.1600-0501.2011.02375.x","article-title":"A Systematic Review of Post\u2010Extractional Alveolar Hard and Soft Tissue Dimensional Changes in Humans","volume":"23","author":"Tan W.
