Treatment of Atrophic Ridges with Titanium Mesh: A Retrospective Study Using 100% Mineralized Allograft and Comparing Dental Stone Versus 3D-Printed Models.

This multicenter study retrospectively evaluated implant survival and bone growth in atrophic ridges that were augmented with titanium mesh and 100% mineralized solvent-dehydrated bone allografts (MSDBA). A secondary objective of this study was to evaluate differences in outcomes by diagnostic model type. Titanium mesh was shaped on a diagnostic wax-up of the patient's jaw: Twenty-three patients (Group 1) had wax-ups on dental stone models, and 16 patients (Group 2) had wax-ups on models fabricated with three-dimensional (3D) printing technology. Clinical and histologic data were analyzed. The average bone gain ranged from 5.94 to 6.91 mm horizontally and 5.76 to 6.99 mm vertically and was not significantly different between the two model groups (P > .05). Implant survival was 100% after 18 to 48 months. Although model type had no significant influence on outcomes, 3D-printed models allowed for faster surgery and served as visual aids for patient education.

Single-Rooted Extraction Sockets: Classification and Treatment Protocol.

Clinicians have many treatment techniques from which to choose when extracting a failing tooth and replacing it with an implant-supported restoration and when successful management of an extraction socket during the course of tooth replacement is necessary to achieve predictable and esthetic outcomes. This article presents a straightforward, yet thorough, classification for extraction sockets of single-rooted teeth and provides guidance to clinicians in the selection of appropriate and predictable treatment. The presented classification of extraction sockets for single-rooted teeth focuses on the topography of the extraction socket, while the protocol for treatment of each socket type factors in the shape of the remaining bone, the biotype, and the location of the socket whether it be in the mandible or maxilla. This system is based on the biologic foundations of wound healing and can help guide clinicians to successful treatment outcomes.
