Abstract

Background: The reconstruction of alveolar ridges for implant placement is still a challenging surgical procedure, especially in the case of extensive vertical and horizontal bone atrophy.

Objective: The objective of the present study was to evaluate the quantity and quality of newly regenerated bone; clinically by means of direct clinical measuring, ridges augmented by autogenous cortical bone associated with autogenous particulate bone graft in the posterior lower jaw defect.

Methods: For the preliminary study, a bone defects in partially edentulous in patient aged 52 years were selected to receive horizontal ridge augumentation prior autolougous bone block and particulate graft. The donor site was the ramus of the same side. Prior the clinical evaluation, periapical X-ray and the cone beam computerized tomography (CBCT) was observed the quality, quantity and the stability the soft and hard tissue healing process, final result and the outcome.

Result: The bone augmentation achieved with this technique created the ideal bone volume of hard and soft tissue, in quantity and quality, for placement of implants.

Conclusion: The surgical technique was found to be easy in terms of technique and surgical trauma.
