Augmentation of the buccal bone plate following tooth extraction using xenogenic bone graft and resorbable membrane: a case report

Bone remodeling occurs following the tooth extraction, and in case we want to be sure that the newly formed bone will be suitable for dental implant placement, it is necessary to do one of the augmentation procedures. The various bone substitutes, such as autografts, allografts, xenografts or alloplastic (synthetic) materials in combination with resorbable and non-resorbable membranes are commonly used to augment the alveolar ridge. In this case report we want to focus on the use of xenograft in combination with native collagen membrane for the augmentation of the buccal bone plate following tooth extraction and prior to dental implant placement. A female patient was referred to an oral surgeon in the Community Healthcare Centre in Osijek. Surgical treatment was required because of root fracture of the tooth 13. After the extraction, detailed curettage of inflammatory tissue was performed. The elevation of full- thickness mucoperiosteal flap showed extensive destruction of buccal bone along with buccal fenestration. The defect was filled by a xenogenic bone graft of bovine origin (Cerabone, Botiss GmbH), and covered by a resorbable membrane (Jason membrane, Botiss GmbH). The wound was closed by single 5/0 sutures. The healing period was neat, and sutures were removed 7 days following the tooth extraction. The patient still needs to wait for full bone regeneration to complete the implant-supported prosthodontic therapy.
