Brief Summary

Review the sponsor-provided synopsis that highlights what the study is about and why it is being conducted.

The aim of this clinic self-control study was to evaluate the trueness of occlusal contact affected by six ceramic materials during chairside fabricating process and offer recommendations for occlusal offset according to different ceramic materials in CEREC CAD/CAM design process.

Detailed Description

Dive into the extended narrative that explains the scientific background, objectives, and procedures in greater depth.

Ten participants were selected for this study. InCoris TZl(ZIR), Celtra Duo(CD), IPS e.max(EMA), UPCERA LICI (LC), Vita enamic(ENA), UPCERA RUNCI (RC) were used to produce crowns for everyone by CEREC chairside CAD/CAM system. The milling trueness, postprocessing trueness and clinical adjustment of occlusal contact were quantitatively analyzed by the ATOS high-precision scanner and Geomagic reverse engineering software.
