Abstract
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.
