目的探讨氧化铝全瓷冠与CAD/CAM氧化锆全瓷冠在前牙修复中的临床效果,并对前牙修复方法的临床效果进行比较,探索两种前牙修复技术的效果差异。方法选取郑州市口腔医院满足前牙修复标准的患者160例,分别采用两种修复技术进行临床治疗。其中采用采用氧化铝全瓷冠技术进行修复的一组为对照组,采用CAD/CAM氧化锆全瓷冠技术进行修复为实验组,12个月后按修正标准对修复体的边缘着色、密合度、形态、颜色、周围龋坏等情况进行评价。结果对照组和实验组患者的修复效果均满足临床效果要求,且两组患者的修复效果所需检测的指标无差异。结论氧化铝全瓷冠技术与CAD/CAM氧化锆全瓷冠技术的前牙修复在美观性、边缘密合性、抗折强度等方面均能满足临床要求。
Objective To investigate the clinical effects of all-ceramic crowns and CAD / CAM zirconia all-ceramic crowns in anterior teeth restoration and to compare the clinical effects of anterior teeth restoration methods and to explore the difference in the effects of the two anterior teeth restoration techniques. Methods Totally 160 patients in Zhengzhou Stomatological Hospital, who met the criteria of anterior teeth restoration, were treated with two kinds of repair techniques. One group using alumina all-ceramic crown repair for the control group, the use of CAD / CAM zirconia all-ceramic crown repair technique for the experimental group, 12 months after the revision of the revised standards on the edge of the coloring, adhesion , Morphology, color, surrounding caries and other conditions were evaluated. Results Both the control group and the experimental group were able to meet the clinical effect, and there was no difference between the two groups in the detection of the effect of the repair. Conclusion The all-ceramic crown technique and the CAD / CAM zirconia all-ceramic crown anterior teeth repair meet the clinical requirements in aesthetics, edge adhesion and flexural strength.
