実験的:Zirconia
10 crowns made of zirconia from 10 individual were milled, post-processed and occlusal adjusted in patients' mouth.
|
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) |
