摘要
目的:评价并比较金合金及钴铬合金嵌体修复后牙缺损的临床效果。方法:选择具有后牙嵌体修复适应证的病例,根据患者对材料的选择将93颗牙分为2组:金合金组48颗,钴铬合金组45颗。治疗完成18个月后,复查患者牙龈情况、边缘密合度、邻接点恢复及固位情况。结果:治疗前2组患者基线资料各项指标均无显著性差异(均P>0.05)。2组患者在治疗完成18个月后牙龈健康、边缘密合度、邻接关系和固位情况方面均无显著性差异(均P>0.05)。结论:钴铬合金嵌体在后牙缺损修复中的临床效果与金合金相比无明显差异,因其良好的合金性能以及明显的价格优势是用于后牙嵌体较为理想的合金材料。
Objective：To evaluate the clinical effect of Au alloy inlays and Co-Cr alloy inlays in restorating posterior teeth defects.Methods：According to the materials chosen by patients,93 cases selected with indications were divided into two groups：48 cases for Au alloy inlays and 45 cases for Co-Cr inlays.We examined the prosthesis for gingival status,marginal fit,adjacent point and retention situation after 18 months restoration. Results：No statistically significant difference was shown in gingival status,marginal fit,adjacent point and retention situation between the two groups after 18 months restoration.Conclusion：There is no significant difference between Co-Cr alloy inlays and Au alloy inlays in the clinical effect during the restoration of posterior teeth defect.So Co-Cr alloy is the ideal materials for the posterior inlays because of its good property and price advantage.
