目的 探讨IPSEmpress2全瓷桥及冠修复效果。 方法 分别制作IPSEmpress1全瓷冠 5 0件、IPSEmpress2全瓷冠 5 0件和全瓷桥 16件 ,及金合金基底烤瓷桥 16件 ,比较IPSEmpress1和IPSEmpress2全瓷冠及IPSEmpress2全瓷桥与金合金基底烤瓷桥修复体颜色、形态、基牙龋患率、修复体的边缘密合度、边缘着色和修复体折断情况 ,随访 3～ 12个月。结果 IPSEmpress2全瓷冠的颜色、形态、基牙龋患率、修复体的边缘密合度、边缘着色与IPSEmpress1无统计学差异 ,在修复体折断率方面IPSEmpress2低于IPSEmpress1(P <0 .0 5 ) ,IPSEmpress2全瓷桥在颜色方面好于金合金基底烤瓷桥 (P <0 .0 5 ) ,其他方面无统计学差异。结论 IPSEmpress2全瓷桥及冠近期修复效果良好 ,值得临床推广应用
Objective To investigate the IPSEmpress2 all ceramic bridge and crown repair effect. Methods 50 pieces of IPSEmpress1 all-ceramic crowns, 50 pieces of IPSEmpress2 all-ceramic crowns, 16 pieces of all-ceramic porcelain bridge and 16 pieces of porcelain-fused ceramic bridge were made respectively. All IPSEmpress1 and IPSEmpress2 all-ceramic crowns and IPSEmpress2 porcelain bridge were compared with gold alloy The color, morphology, abutment caries prevalence, the marginal confluence of the prosthesis, the marginal coloring and the fracture of the prosthesis were observed. The patients were followed up for 3 to 12 months. Results There was no significant difference in the color, morphology, abutment caries prevalence, marginal confluence and edge coloration between IPSEmpress2 and IPSEmpress1. IPSEmpress2 was lower than IPSEmpress1 (P <0.05) IPSEmpress2 full ceramic bridge in color is better than the gold alloy base ceramic bridge (P <0. 05), the other no significant difference. Conclusion IPSEmpress2 all-ceramic bridge and crown recently repair effect is good, it is worthy of clinical promotion and application
