Summary

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

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.

Conditions

• Tooth Defect

Interventions

Type	Name	Description
OTHER	Chairside CAD/CAM ceramic materials for dental restoration	6 crowns made from 6 chairside ceramic materials were milled by CEREC MCXL-EF mode for mandibular first molar of each participant. The six materials are as follows: ZIR: InCoris TZI (Dentsply Sirona, York, PA)， CD: Celtra Duo (Dentsply Sirona, York, PA), EMA: e.max CAD (ivoclar, Vivadent AG), LC: LiCi (UPCERA, China), ENA: Vita Enamic (Vita Zahnfabrik, Bad Sackingen, Germany) RC: RunCi (UPCERA, China)
