Preliminary Clinical and Histologic Evaluation of a Bilateral 3-Dimensional Reconstruction in an Atrophic Mandible: A Case Report

This article presents the case report of the bilateral 3-dimensional reconstruction of a posterior mandible in a 48-year-old woman. Titanium meshes and Regenaform demineralized freeze-dried bone allograft were used for bone regeneration. After 5 months the titanium mesh was removed, and after another 4 months, 4 Straumann sandblasted, large-grit, acid-etched implants were placed, 2 on each side of the mandible. During implantation a bone specimen was collected and sent for histologic examination. The definitive fixed prosthesis was fabricated after an additional 4 months. The clinical and histologic results are shown. The implants were followed for 18 months after implant loading; no signs of bone loss or infection were observed.
