Restoration of Maxillary Anterior Defect using Autogenous Block Graft and Optimizing the Esthetics using Zirconia Restoration

Abstract

The placement of dental implants in the anterior maxilla is a challenge for clinicians because of patients’ exacting esthetic demands and difficult pre-existing anatomy. An atrophic alveolar ridge frequently causes functional, esthetic and prosthodontic problems. New approaches to implant therapy are available for patients with insufficient bone volume, like bone grafts, which may be autografts, xenografts, allografts or alloplasts. In maxillofacial reconstruction, the autogenous bone graft is still the “gold standard” for bone augmentation procedures. All ceramic crown emerging from a healthy peri-implant mucosa would fulfil the ultimate goal of a life-like restoration. This article describes a method for harvesting intramembranous monocortical bone from the symphysial region for horizontal alveolar ridge augmentation followed by implant placement in the anterior maxilla. This method provided enough bone volume for insertion of an implant in an optimal position with total bony coverage and esthetics.
