二氧化锆与金合金烤瓷冠修复用于上前牙牙体缺损的疗效对比

Two zirconia and gold alloy porcelain crowns used on curative effect of anterior teeth anterior teeth defect

目的观察二氧化锆全瓷冠与金合金烤瓷冠在上前牙牙体缺损修复中的效果比较。方法如皋市人民医院2014年1月至2015年1月收治的95例上前牙牙体缺损病人为研究对象,按病人自行选择修复方法将95例病人分为观察组(n=49)和对照组(n=46),观察组行二氧化锆全瓷冠修复,对照组行金合金烤瓷冠修复。修复后对病人进行随访观察,对比两组病人修复后的牙体的边缘密合度、牙体折裂、牙体颜色等情况,并对两组病人修复后出现的不良反应发生率进行比较。结果 (1)观察组病人修复后在边缘密合度、牙体折裂、修复体颜色及牙龈健康状况等均显著优于对照组(χ2=6. 957、12. 087、10. 840、12. 711,P=0. 031、0. 002、0. 004、0. 002)。(2)观察组病人不良反应发生率为4. 08%(2/49),显著低于对照组的21. 74%(10/46)(χ2=6. 703,P=0. 010)。结论二氧化锆全瓷冠相比于金合金烤瓷冠,在修复上前牙牙体缺损的疗效、牙体颜色、牙龈健康具有显著优势,且安全性好,在临床上有较高的应用价值。

Objective To observe the effect of two zirconia all ceramic crown and gold alloy porcelain crown on the restoration of anterior maxillofacial defects.Methods in our hospital from January 2014 2015 year in January 95 cases of patients with anterior teeth defect as the research object,according to the patients to choose repair methods 95 patients were divided into observation group(n=49)and control group(n=46),the observation group was treated with two zirconia all ceramic crowns,while the control group was treated with gold alloy porcelain crown.Repair patients were followed up,the teeth were compared between two groups after the restoration of the edge density,tooth fracture,tooth color,and the adverse reactions of two groups of patients after repair compared the incidence rate.Results(1)in the observation group,the marginal density,the tooth fracture,the restoration color and the gingival health status of the observation group were significantly better than those of the control group(χ^2=6.957、12.087、10.840、12.711,P=0.031、0.002、0.004、0.002).(2)the incidence of adverse reactions in the observation group was 4.08%(2/49),which was significantly lower than that of the control group(21.74%)(10/46)(χ^2=6.703,P=0.010).Conclusion Compared with gold alloy PFM crown,zirconia all-ceramic crown has significant advantages in repairing upper anterior teeth defect,tooth color and gingival health,good safety and has high application value in clinic.
