About this study

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.

Primary outcomes

  1. crown adjustment times

    Time frame: 1-6 month

    Using the occlusal relationships recorded with the occlusense recorder prior to the restoration preparation as a guide, the occlusal contacts will be adjusted at maximum intercuspation (ICM) and during protrusive and lateral excursive movements. The duration of these adjustments will be measured.
