目的
探讨In-Ceram 全瓷冠结合铸造金属桩修复上颌前牙牙体缺损的临床效果。
方法
60 例患者,184 颗牙随机平均分成两组,实验组以In-Ceram 全瓷冠和铸造金属桩修复;对照组以Ni-Cr 金属烤瓷冠和铸造金属桩核修复。 采用美国加利弗尼亚牙科协会的评价标准对临床结果进行追踪评价。
结果
经3 年的临床观察,实验组的颜色满意程度、牙龈着色、牙龈反应、边缘适合性及边缘着色均优于对照组,两组间差异有统计学意义(P<0.01);修复体完整度方面两组差异无统计学意义(P=0.65)。
结论
In-Ceram 全瓷冠修复牙体缺损的临床效果优于金属烤瓷冠。
Objective
To investigate the clinical effect of In-Ceram all ceramic crown and cast post-core in restoring maxillary anterior tooth defect.
Methods
A total of 60 patients(184 teeth) were randomly divided into two groups: in the experimental group, 30 patients of 92 teeth were restored with In-Ceram all ceramic crown and cast post-core; and the control group,30 patients of 92 teeth were restored with Ni-Cr porcelain-fused-to-ceramic crown and cast postcore. The California Dental Association quality assessment evaluation system was used to assessing the clinical results.
Results
After 3-year' s follow-up, significant defference was observed between the two groups (P<0.01). The color stability, gingival coloration, gum reaction,margin adequacy and marginal discoloration of the experimental group were superior to those of the control group. However, there was no significant difference (P=0.65) with respect to the prosthesis integrity.
Conclusions
In-Ceram all ceramic crown has a better effect on maxillary anterior tooth defect restoration compared with porcelain-fused-to-ceramic crown.
