全瓷高嵌体修复治疗后牙严重牙体缺损的效果

Effect of all-ceramic onlay restoration on severe posterior tooth defect

目的研究全瓷高嵌体修复对后牙严重牙体缺损的治疗效果。方法将我院收治的160例后牙严重牙体缺损患者按治疗方式的不同分为全瓷冠组(80例,全瓷冠修复)和全瓷高嵌体组(80例,全瓷高嵌体修复)。比较两组的治疗效果。结果全瓷高嵌体组的修复满意度高于全瓷冠组(P<0.05)。修复后1年,全瓷高嵌体组TNF-α、AST水平均低于全瓷冠组(P<0.05)。全瓷高嵌体组牙齿折断、瓷体脱落发生率低于全瓷冠组(P<0.05)。结论与全瓷冠修复相比,全瓷高嵌体修复严重后牙牙体缺损,能够提高修复满意度,降低牙齿折断、瓷体脱落发生风险。

Objective To study the therapeutic effect of all-ceramic onlay restoration on severe posterior tooth defect.Methods A total of 160 patients with severe posterior tooth defect admitted in our hospital were divided into all-ceramic crown group(n=80,all-ceramic crown restoration)and all-ceramic onlay group(n=80,all-ceramic onlay restoration)according to different treatment methods.The therapeutic effects of the two groups were compared.Results The restoration satisfaction of the all-ceramic onlay group was higher than that of the all-ceramic crown group(P<0.05).One year after restoration,the levels of TNF-αand AST in the all-ceramic onlay group were lower than those in the all-ceramic crown group(P<0.05).The incidences of tooth fracture and porcelain body falling off in the all-ceramic onlay group were lower than those in the all-ceramic crown group(P<0.05).Conclusion Compared with all-ceramic crown restoration,all-ceramic onlay restoration can improve the satisfaction of restoration,reduce the risks of tooth fracture and porcelain body falling off.
