Although its clinical success is documented, comprehensive studies combining histological and radiographic evaluations remain limited. This case report addresses this gap by detailing a novel approach using autogenous particulate dentin combined with cancellous allograft and a long\u2010lasting absorbable barrier membrane (lasso\u2010guided bone regeneration technique) for horizontal ridge augmentation.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Methods and Results<\/jats:title>\n                    <jats:p>A 49\u2010year\u2010old female presented with insufficient alveolar ridge width (Seibert Class I) at edentulous sites #12 and #14, necessitating bone augmentation before implant placement. The procedure involved a layered approach: Cancellous allograft (internal layer, faster remodeling) followed by autogenous particulate dentin (outer layer, slower remodeling). A bovine pericardium membrane was used to isolate the graft site and promote healing. Six months post\u2010surgery, cone\u2010beam computed tomography scans demonstrated significant alveolar ridge width gains of 4.64\u00a0mm at #12 and 4.21\u00a0mm at #14. Implants were successfully placed, and a bone core harvested at the 4\u2010month mark confirmed the slow remodeling rate of the dentin particles compared to the allograft. One year post\u2010restoration, the implants remain functional.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Conclusion<\/jats:title>\n                    <jats:p>This case report highlights the efficacy of the layered approach using autogenous particulate dentin, particularly for space maintenance. The slower remodeling rate of dentin suggests its suitability as an outer layer, enhancing long\u2010term stability. This innovative technique and material selection may represent a significant advancement in alveolar ridge augmentation procedures. Further studies are warranted to confirm these findings and determine optimal applications in the long term.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Key points<\/jats:title>\n                    <jats:p>\n                      <jats:list list-type=\"bullet\">\n                        <jats:list-item>\n                          <jats:p>The case demonstrates that a biologically driven layered grafting approach\u2014placing cancellous allograft internally for faster remodeling and autogenous particulate dentin externally for slower turnover and superior space maintenance\u2014is an option to perform horizontal ridge augmentation by mimicking natural bone architecture.<\/jats:p>\n                        <\/jats:list-item>\n                        <jats:list-item>\n                          <jats:p>Histologic findings highlight that dentin particles remodel very slowly yet remain well integrated within the grafted site without complications, contributing to stability while allowing substantial formation of vital bone.

A 49\u2010year\u2010old woman had insufficient bone width in the upper jaw, which made implant treatment impossible without bone augmentation. To solve this, the treatment combined two materials: donated human bone on the inside, which remodels quickly, and the patient's own tooth material, ground into small particles, on the outside, which remodels more slowly and helps maintain space. A protective membrane was used to stabilize the graft and promote healing. After 6 months, 3D scans showed a significant increase in bone width, allowing implants to be placed successfully. A small bone sample confirmed the slow remodeling of the tooth particles compared with the donated bone. One year after the final restoration, the implants remained functional and stable. This technique suggests that using a patient's own tooth material, combined with other grafting materials, may provide a safe and effective alternative for jawbone reconstruction. It may also reduce the need for animal\u2010derived products while improving long\u2010term stability for implant treatments.<\/jats:p>\n                  <\/jats:sec>","DOI":"10.1002\/cap.70046","type":"journal-article","created":{"date-parts":[[2026,3,8]],"date-time":"2026-03-08T16:59:32Z","timestamp":1772989172000},"page":"637-645","update-policy":"https:\/\/doi.org\/10.1002\/crossmark_policy","source":"Crossref","is-referenced-by-count":0,"title":["Combination of autogenous dentin graft and allograft for horizontal ridge augmentation: A case report"],"prefix":"10.1002","volume":"16","author":[{"ORCID":"https:\/\/orcid.org\/0000-0002-4647-9761","authenticated-orcid":false,"given":"Kosuke","family":"Kashiwagi","sequence":"first","affiliation":[{"name":"Private Practice  Tokyo Japan"},{"name":"Department of Periodontics University of Pennsylvania School of Dental Medicine  Philadelphia Pennsylvania USA"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-1441-1156","authenticated-orcid":false,"given":"Yu\u2010Cheng","family":"Chang","sequence":"additional","affiliation":[{"name":"Department of Periodontics University of Pennsylvania School of Dental Medicine  Philadelphia Pennsylvania USA"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-9159-9615","authenticated-orcid":false,"given":"Tun\u2010Jan","family":"Wang","sequence":"additional","affiliation":[{"name":"Department of Periodontics University of Pennsylvania School of Dental Medicine  Philadelphia Pennsylvania USA"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0009-0008-6454-7490","authenticated-orcid":false,"given":"Dumitru","family":"Gogarnoiu","sequence":"additional","affiliation":[{"name":"Department of Periodontics University of Pennsylvania School of Dental Medicine  Philadelphia Pennsylvania USA"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Rodrigo","family":"Neiva","sequence":"additional","affiliation":[{"name":"Department of Periodontology and Oral Implantology Temple University Maurice H.
