目的:比较IPS-Empress Ⅱ铸瓷贴面和Targis树脂贴面修复后3年的临床疗效。方法:选取14名患者制作IPS-Empress Ⅱ铸瓷贴面50个,22名患者制作Targis树脂贴面86个。使用改良CDA/Ryge标准对两种贴面修复后三年的颜色匹配、表面质地、边缘着色和完整性等指标进行评价,比较两者的临床成功率和患者满意度。结果:IPSEmpress II铸瓷贴面3年存留率为94.0%,Targis贴面为90.7%;IPS-Empress Ⅱ铸瓷贴面修复患者主观满意度为92.0%,Targis贴面为88.4%;两者在颜色匹配、边缘着色和边缘完整性方面没有明显差异;在表面质地上IPS-Empress Ⅱ铸瓷贴面优于Targis树脂贴面。结论:IPS-Empress Ⅱ铸瓷贴面和Targis树脂贴面均是良好的修复系统,IPS-Empress Ⅱ铸瓷贴面的表面性能优于Targis树脂贴面。
OBJECTIVE: To compare the clinical efficacy of IPS-Empress II cast-iron veneer and Targis resin veneer for 3 years. Methods: Forty patients were selected to make 50 IPS-Empress II castings, and 22 patients were given Targis resin veneers. The improved CDA / Ryge criteria were used to evaluate the three-year color matching, surface texture, edge coloring, and completeness of the two veneer repairs. The clinical success rate and patient satisfaction were compared between the two veneers. Results: The three-year survival rate of IPSEmpress II was 94.0% and the Targis veneer was 90.7%. The subjective satisfaction of patients with IPS-Empress Ⅱ cast-iron veneering was 92.0% and that of Targis veneer was 88.4% There was no significant difference in color matching, edge coloration and edge integrity; IPS-Empress II castings were superior to Targis resin laminates on the surface texture. Conclusions: Both IPS-Empress II castings and Targis resin veneers are good repair systems. The surface properties of IPS-Empress II castings are superior to those of Targis resin veneers.
