微波烧结和常规烧结氧化锆全瓷冠适合性的比较
Comparison the fitness of zirconia ceramic crown sintered by microwave sintering method and conventional sintering method
摘要
Abstract
Objective:To study the effect of different sintering method on the marginal and internal adaptation of Cercon zirconia crowns. Method:A first premolar teeth was prepared and replicated in to ten resin castes. The units were randomly assigned to two groups and the crowns were made by CAD/CAM system. Group one was sintered by manufacturers recommend conventional second-time sintering process. Group two was sintered by microwave second-time sintering process. All crowns adhered to the corresponding dies and compare their adaption through statistical analysis. Result:Marginal fit and axial plane of zirconia ceramic crowns sintered by two methods have no significant differences (P>0.05). Shoulder suitability and occlusal surface have significant differences (P <0.05).Conclusion:Microwave sintered Cercon zirconia crowns appeared to have clinically acceptable marginal fit.关键词
