Onlay Grafting with FDBA Block Bone for Reconstruction of Localized Maxillary Ridge Defect

Abstract

Ab s t r Ac t Aim: The aim of the present case was to evaluate the efficacy of freeze-dried bone allograft (FDBA) bone block in the augmentation of atrophied maxillary esthetic zone. Background: The placement of endosseous dental implants is often hampered by unfavorable anatomy of the alveolar bone thereby making it difficult for the placement of implant in an optimal prosthetic position. The loss of width of the residual alveolar ridge necessitated measures which could refurbish the lost dimensions for adequate bone availability for the implant placement. Case description: Here we report the successful management of atrophic ridge condition in the maxillary anterior esthetic zone wherein the placement of implant was made possible by the placement of FDBA bone block allograft obtained from the tissue bank. The predictable osseointegration was achieved after placement of a regular platform implant and restoration of the complete esthetics, and the patient satisfaction was attained. Conclusion: Allogenic bone blocks can serve as a good alternative for autogenous bone owing to its unlimited availablility, reduced donor site morbidity, increased patient compliance, and decreased treatment time. Clinical significance: Allogenic bone block confers an excellent alternative to autogenous bone blocks for the augmentation of atrophic maxillary ridges for the placement of endosseous implant.
