The usage of biphasic calcium-phosphate paste and native collagen membrane following tooth extraction: a case report

Failures in endodontic treatments, along with trauma, are still the most common causes that lead to tooth loss. Dental implants are, for sure, the best treatment option in case of one or more teeth missing. However, in situations when there is insufficient width and height of the residual alveolar ridge, there is a need for augmentation procedures. This case report will present an alveolar ridge augmentation following tooth extraction. A healthy 25-year-old female was referred to a dental surgeon in Community Healthcare Centre in Osijek, for tooth extraction due to endodontic treatment failure. An intraoral x- ray showed bone destruction in the periapical region of tooth 25. It was decided to place an implant after tooth extraction. The site of extraction was exposed via elevation of a fullthickness flap. Tooth extraction was done atraumatically, and afterwards, detailed curettage was performed. The site of extraction was filled by biphasic calcium phosphate paste (BCP-paste) (Maxresorb inj., Botiss GmbH) and the whole defect was covered by a resorbable membrane (Collprotect, Botiss GmbH). The wound was closed with 5/0 single sutures. Seven days after surgery, intraoral x- rays showed volume stability of the augmented area and no dislocation of the bone graft. This case highlights the use of BCP-paste and native collagen membrane before the implant placement. The bone defect was filled excellently due to the viscosity of BCP-paste. Also, the material showed easy handling. Follow up is needed to define volume stability of augmented area six months after healing and before the re-entry procedure.
