This multicenter study retrospectively evaluated implantsurvival and bone growth in atrophic ridges that were augmented with titaniummesh and 100% mineralized solvent-dehydrated bone allografts (MSDBA). Asecondary objective of this study was to evaluate differences in outcomes bydiagnostic model type. Titanium mesh was shaped on a diagnostic wax-up of thepatient’s jaw: Twenty-three patients (Group 1) had wax-ups on dental stonemodels, and 16 patients (Group 2) had wax-ups on models fabricated withthree-dimensional (3D) printing technology. Clinical and histologic data wereanalyzed. The average bone gain ranged from 5.94 to 6.91 mm horizontally and5.76 to 6.99 mm vertically and was not significantly different between the twomodel groups (P > .05). Implant survival was 100% after 18 to 48 months.Although model type had no significant influence on outcomes, 3D-printed modelsallowed for faster surgery and served as visual aids for patient education.
