Adjustment Period for Partial Crowns

Evaluation of the Time Required for Clinical Adaptation of Partial Dentures Based on Additive and Subtractive Manufacturing: A Randomized Controlled Clinical Study

The aim of this study is to compare the occlusal accuracy of CAD/CAM milled and 3D printed crowns guided by an occlusal device, starting from the same digital CAD design.

The subject of this study is to compare the occlusal closure performance of onlay restorations produced from CAD-CAM blocks and onlay restorations produced using 3D printer technology. The Occlusense device has the capacity to measure occlusal contact points and force distribution through digital pressure sensors, providing accurate data in clinical research.

This study is a randomized clinical trial conducted using a split-mouth design. Onlay restorations produced using different manufacturing methods will be applied to two teeth of the same patient, and the occlusal closures of both restorations will be evaluated.
