Summary

This study compares two types of implant-supported dentures—one made the usual way and one 3D-printed—using two different snap-on attachment systems. Twenty adults with no teeth and good overall health will try both denture designs to see which stays in place better, causes less wear, and feels more comfortable. The goal is to improve how well these dentures work and how satisfied patients are.
