Horizontal Bone Augmentation in the Pre-Maxilla Region with Used the Bone Block Xenogeneic Origin - Clinical and Tomographic Analysis

Tooth loss, especially in the anterior region, generates a loss of local bone structure affecting the aesthetics and function for the patient and a viable tactic is the use of deproteinized bovine bone block graft. This reconstructive method allows the possibility of partial or total reconstruction of the maxilla and mandible in a safe and predictable way, where it seeks the maintenance of the three-dimensional structure, viability of bone neoformation and favoring implant-supported rehabilitation. This case report aims to reveal and support the longitudinal follow-up of 5 years of a horizontal alveolar reconstruction in the anterior maxillary region with heterogeneous bone block and subsequent implantation and rehabilitation with metal-ceramic crown.
