Occlusal Contact Trueness Affected by Six Chairside CAD/CAM Ceramic Materials

21. april 2022 opdateret af: Hao Yu, Fujian Medical University

Quantitative Clinical Evaluation of the Occlusal Contact Trueness Affected by Six Chairside CAD/CAM Ceramic Materials：a Self-control Study

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.

Detaljeret beskrivelse

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.
