摘要
目的:比较钛合金和镍铬合金烤瓷冠的临床效果。方法:收集本科260例需金属烤瓷冠修复的患者制作184个单位钛合金和220个单位镍铬合金烤瓷冠修复体,观察修复体颜色、固位、颈缘密合度,18个月后再次观察以上指标及龈缘着色、冠的完整性、继发龋情况。结果:两组在颈缘着色方面差异有统计学意义(P<0.01),其余指标相似,均未发生冠瓷折裂、继发龋。结论:钛合金烤瓷修复体比镍铬合金烤瓷修复体有更好的临床效果。
Objective：To compare the clinic outcomes of ceramic crowns made of titanium alloy and Ni-Cr alloy. Methods： 260 patients who required repair with metal-ceramic crowns were managed using 184 Ti-lite and 220 Ni-Cr alloy units. The color, retention and marginal fitness of these units were observed immediately. After 18 months, these indices, along with marginal color, porcelain defect and secondary caries, were further observed. Results： Significant difference between the two crowns was shown in marginal color （P 〈0.01 ） but not in others. None of the patients were found to be with porcelain defect and secondary caries. Conclusion： The clinical outcomes of Ti-lite alloy ceramic crowns appear better than those of Ni-Cr alloy ones.
