3种玻璃陶瓷与Wieland Zenostar氧化锆相互摩擦的耐磨性比较
Comparison of wear resistance of three kinds of glass ceramics and Wieland Zenostar zircona
摘要
Abstract
Objective:To explore the differences of wear resistance of three kinds of glass ceramics and Wieland Zenostar zircona (Zenostar) , and to clarify their influencing factors.Methods:Zenostar were made into flat-shaped specimens (zirconia base sample group) and hemisphere-shaped specimens (zirconia pair grinding group) .There kinds of glass ceramics IPS Empress (Empress) , IPS e.max CAD (e.max) , VITA Suprinity (Suprinty) were used as base specimens.Each group was exposed to UMT-2testing machine to simulate the clinical service.The wear depthes of base specimens were detected by laser confocal scanning.Scanning electron microscope (SEM) was used to evaluate the wear surfaces.Results:In zirconia base sample group, there were no significant differences in the maximum wear depthes to Zenostar between the three kinds of glass ceramics (P>0.05) .In zirconia pair grinding group, the maximum wear depthes ranked as follows:Zenostar group<e.max group≈Empress group<Suprinity group;there was no significant difference between e.max group and Empress group (P>0.05) , but there were significant differences between other groups (P<0.01) .The SEM results showed that the wearing surface of the Zenostar in zirconia base sample group was relatively smooth;whereas the wearing surface of Empress in zirconia pair grinding group was rougher with alarge area of clebris desquamation surface.Conclusion:The wear resistance of the three kinds of glass ceramics to Zenostar is related to the compositions and the chemical structures of materials.关键词
