Valdec S Pasic P Soltermann A Thoma D Stadlinger B Rücker M 2017 INTRODUCTION Ridge preservation can be performed with autologous bone, alloplastic bone substitute material or a combination of both. Dentin is similar to bone in its chemical composition. In its use as bone substitute material, it undergoes a remodelling process and transforms to bone. The presented case report introduces a technique in which the extraction socket is augmented with autologous, particulated dentin. MATERIAL AND METHODS The fractured, non-savable mesial incisor of the upper jaw was carefully extracted in axial direction. After the extraction, the tooth was cleared from remaining periodontal tissue. The vital pulp tissue or a root canal filling, enamel and cementum were also removed. Following the particulation of the remaining dentin in a bone mill, the dentin particles were immediately filled orthotope into the alveolar socket. The soft tissue closure was performed with a free gingival graft of the palate. RESULTS After an observation period of 4 months, an implant was placed in the augmented area, which osseointegrated successfully and could be restored prosthodontically in the following. The results of this method showed a functional and aesthetic success. CONCLUSION The pre-implantological, autologous ridge preservation with dentin could be performed successfully. For the establishment of dentin as augmentation material for jaw augmentation procedures, a prospective, clinical trial is now necessary. application/pdf https://sonar.ch/global/documents/225926 eng info:eu-repo/semantics/altIdentifier/doi/10.1186/s40729-017-0071-9 info:eu-repo/semantics/altIdentifier/pmid/28361377 info:eu-repo/semantics/openAccess International journal of implant dentistry. - 2017 Alveolar ridge preservation Autologous augmentation Bone augmentation Bone substitute Particulated dentin Alveolar ridge preservation with autologous particulated dentin-a case series. http://purl.org/coar/resource_type/c_6501
