Abstract

Introduction: Implant rehabilitation depends on the presence of bone of sufficient height and thickness for fixation and osseointegration of the implants. In cases of hypoplastic premaxillae, several options may be considered to compensate for or correct this bone defect, such as the placement of short implants or the augmentation of bone height and thickness. To increase its volume several techniques could be performed, such as: Guided bone regeneration (GBR), bone block graft, Le Fort I osteotomy with interpositional bone graft, and distraction osteogenesis. The most established technique for increasing alveolar bone volume is GBR associated with autologous, heterologous, or alloplastic grafts. Collagen membranes are commonly used in guided bone regeneration (GBR) procedures associated with exercises due to their biocompatibility. This article is a case report of Guided Bone Regeneration for a bone defect in the anterior maxilla, using an attachment in a bone block of heterogeneous origin associated with PRF and a collagen membrane. Case report: Patient JMLF, 52 years old, presented premature loss of tooth 11 and 21 and was wearing a removable partial denture. We performed the placement of 2 bone blocks of heterogeneous origin of 10X10X5, thus filling the spaces between the block and the recipient bed with particulate bone of heterogeneous origin and covering the grafts with a specific high-resistance collagen membrane of 20x30mm. Conclusion: guided bone regeneration (GBR), using bone block graft of heterogeneous origin associated with Platelet-rich fibrin (PRF) and collagen membrane, for reconstruction of bone defects performed prior to rehabilitation with dental implants, proved to be an effective way to gain volume and bone height in the anterior maxilla.
