ABSTRACT
Objective:
In order to optimize the crystallization technics, the effects of heat-treatment on the flexible strength and microstructure of a novel dental mica glass-ceramic were studied in present study.Methods:
7 groups were treated respectively with different crystallization temperature and different crystallization time.Then the flexible strength, X-ray diffraction (XRD)and scanning electron microscope(SEM) were used to study the flexible strength and microstructure of such a novel dental mica glass-ceramic.Results:
The result of the study indicated that along with the rise of crystallizing temperature and crystallizing time, this dental mica glass-ceramic showed the peak of bending strength (173.68 MPa) at 680 ℃ for 120 min.Conclusion:
This material is promising as esthetic all-ceramic dental material.
