摘要： 目的:分析比较复合树脂充填与LavaTM Ultimate优韧瓷嵌体修复青少年第一恒磨牙大面积缺损的临床效果。方法:将在我院治疗的62名患儿84颗大面积缺损的第一恒磨牙随机分成AB两组,A组采用LavaTM Ultimate优韧瓷嵌体在计算机辅助设计 /计算机辅助制作(CAD /CAM)下修复,B组采用复合树脂充填修复,定期复查,分别在6个月和12个月后参照改良FDI标准,对两组的修复效果进行评价。结果:6个月后两组各评价指标均无显著差异( >0.05);12个月后AB两组表面染色、边缘染色、边缘适应性和术后敏感性比较差异无统计学意义(P>0.05);但在表面光泽度、折裂与保留以及龋齿再发、腐蚀、脱落方面,A组效果优于B组,差异有统计学意义(P<0.05)。结论:对于有大面积缺损的第一恒磨牙,LavaTM Ultimate优韧瓷在抗折,表面光泽度和再发龋方面的远期效果优于树脂,是一种良好的修复材料,值得大力推广。

Abstract: Objective: To compare the clinical effect of filling with composite resin and LavaTM Ultimate composite resin nanoceramics inlay in repairing children first permanent molars with massive defects. Methods: The first permanent molars of 84 massive defects in 62 children treated in our hospital were randomly divided into two groups: group A was repaired with LavaTM Ultimate composite resin nanoceramics inlay under CAD/CAM, group B was repaired with composite resin and regularly followed up. The effect of the two groups was evaluated with reference to the modified FDI standard after 6 and 12 months, respectively. Results: Six months later, there was no significant difference between two groups (P>0.05). After 12 months, there were no significant differences in surface staining, margin staining, marginal adaptation, and postoperative sensitivity between two groups (P>0.05), but the effect of group A was superior to that of group B in comparison of surface luster, fractures, retention, recurrence of caries, erosion, and exfliation (P<0.05). Conclusion: For the first permanent molars with severe defects, the long-term effect of LavaTM Ultimate excellent-toughness porcelain is superior to resin in terms of fracture resistance, surface luster, and recurrence of caries, and is a good restorative material, which deserves to be vigorously promoted.
