Treatment of buccal fenestration associated with periradicular lesion using biphasic calcium phosphate paste and native collagen membrane: a case report

Introduction: Despite numerous options in treating the periapical lesion, there are still failures in endodontics, which leads to tooth loss. Augmentation procedures performed prior dental implant placement, ensure the adequate height and width of alveolar bone, which is essential to achieve optimal aesthetics and functional rehabilitation. The aim of this case report is to present alveolar ridge augmentation following extraction of the tooth with the extensive periapical lesion. Case report: A healthy 19-years-old female was referred to an oral surgeon in Community Healthcare Center in Osijek, for tooth extraction due to endodontic treatment failure. An orthopantomogram showed severe bone destruction in periapical region of tooth 36. The patient was informed about treatment options after tooth extraction and decided to do implant-supported prosthetics at the site of extraction. The site of extraction was exposed via elevation of a mucoperiosteal flap. Elevation of mucoperiosteal flap showed extensive buccal fenestration. Atraumatic tooth extraction was performed and was followed by curettage of the infected tissue in the socket. The socket was filled with biphasic calcium phosphate paste (BCP-paste) (Maxresorb inj., Botiss GmbH) and whole defect was covered by resorbable membrane (Collprotect, Botiss GmbH). Primary closure was achieved by using 5/0 single sutures. The healing period was uneventful. Seven days after the surgical procedure, control Cone Beam Computed Tomography (CBCT) showed no dislocation of bone substitute and good volume stability of the bone graft. Conclusion: This case highlights the use of BCP-paste and native collagen membrane in extensive bone defect due to the periapical lesion. The viscosity of BCP-paste allowed excellent filling of the three dimensional bone defect and easy handling during surgical procedure. Follow-up is needed to determine volume stability six months after healing and prior implant placement.
