HORIZONTAL-GUIDED BONE REGENERATION USING A TITANIUM MESH AND AN EQUINE BONE GRAFT

The use of a pre-shaped titanium mesh in combination with a mixture of autologous bone and an equine enzymatically deantigenated xenograft

The present work describes a horizontal ridge augmentation in which a titanium mesh was preshaped by adapting it to a stereolithographic model of the patient’s jaw that was fabricated from CT scans.  The 54-year-old patient, missing the right mandibular second bicuspid, first molar, and second molar, had her atrophic ridge augmented with a 30:70 mixture of autogenous bone and equine, enzyme-deantigenic collagen-preserved bone substitute. Two conical implants were inserted concomitantly in the second bicuspid and first molar positions, and the site was protected with the preshaped mesh.  Preshaping the mesh on a model of the patient’s mandible shortened the surgical time and enabled faster mesh placement. Two years after surgery, the implants were perfectly functional, and the bone width was stable over time as shown by radiographic controls. Histological analysis of the bone sample showed the heterologous biomaterial to be biocompatible and undergoing advanced remodeling and replacement with newly formed bone.
