NCT07051590 | Not Yet Recruiting

• 1 other identifier: restorative dentistry
• Study Type: interventional
• Target: 20
• Locations: 1 country
• Sites: 1

Brief Summary

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.

Conditions

Deep Caries Lesion of Pemanent Teeth

Keywords

3D; occlusense; partial crown; cad/cam

Outcome Measures

Primary Outcomes (1)

• crown adjustment times

  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.

  1-6 month

Model Details: The subject of this study is to compare the occlusal closure performance of onlay restorations produced from CAD-CAM blocks with 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
