Clinical Outcomes of 3D Printed and Milled Complete Dentures

Официальное название

An Open, Single-center, Prospective, Randomized, Two-armed, Interventional, Post-market Clinical Investigation of 3D Printed Complete Dentures and Milled Complete Dentures During a 5-year Follow-up Period

Обзор

This is a two-armed, single-center clinical study evaluating performance, efficacy and safety of three dimensional (3D) printed complete dentures and milled complete dentures during a 5-year follow-up period. The primary objective of this clinical investigation is to evaluate survival rate, i.e. subjects with survived dentures in both upper and lower jaw, of 3D printed complete dentures and milled complete dentures after 1 year (in each of the groups separately).
