氧化锆桩与纤维桩修复上前牙残根和残冠的效果比较

Effect comparison of the zirconia post and fiber post in restoring the residual root and crown of upper anterior teeth

目的探讨氧化锆桩与纤维桩在修复上前牙残根和残冠的疗效。方法选择2018年2月至2019年12月徐州医科大学附属第三医院牙科收治的61例上前牙残根和残冠患者作为研究对象,共计84颗患牙,采用随机数字表法将其分为A组(30例,44颗牙)和B组(31例,40颗牙)。A组采用纤维桩修复,B组采用氧化锆桩修复,桩核冠修复后制定牙本质肩领及牙体,最后进行烤瓷冠修复并粘固。两组均给予1年随访,比较两组牙残根修复的成功率,修复失败情况及修复1年后咀嚼效能。结果B组的修复成功率(90.00%)与A组(77.27%)比较,差异无统计学意义(P>0.05);B组桩核脱落或折断、牙龈炎症、牙龈边缘着色、牙根折裂的发生率与A组比较,差异无统计学意义(P>0.05);B组患牙修复1年后咀嚼效能总有效率与A组比较,差异无统计学意义(P>0.05)。结论氧化锆桩与纤维桩在上前牙残根和残冠修复中均可取得良好治疗效果,成功率及对患者咀嚼效能影响方面均无明显差异,临床上可根据患者具体情况选择合适的桩核材料。

Objective To investigate the effect of zirconia post and fiber post in restoring the residual root and crown of upper anterior teeth.Methods A total of 61 patients with residual roots and crowns of upper anterior teeth who were admitted to the Third Affiliated Hospital of Xuzhou Medical University from February 2018 to December 2019 were selected as the research subjects.A total of 84 teeth were selected and divided into group A(30 cases,44 teeth)and group B(31 cases,40 teeth)according to the random number table method.Group A was repaired with fiber posts,and group B was repaired with zirconia posts.After the post-core crown restoration,the dentin shoulder collar and tooth body were prepared,and finally the porcelain crown was repaired and cemented.Both groups were followed up for 1 year.The success rate of restoration of residual roots,failure of restoration and chewing efficiency 1 year after restoration were compared in the two groups.Results There was no significant difference in the restoration success rate of group B(90.00%)and group A(77.27%)(P>0.05).In group B,the incidence of post-core loss or fracture,gingival inflammation,staining of the gingival margin,and root fracture was not statistically different from that of group A(P>0.05).The total effectiveness rate of chewing efficiency was compared between group B and group A one year after restoration of the tooth,and the difference was not statistically significant(P>0.05).Conclusion Both the zirconia post and the fiber post can achieve good therapeutic effects in the restoration of the residual root and crown of the upper anterior teeth,and there is no significant difference in the success rate or the effect on the patient′s chewing efficiency.Clinically,the appropriate one can be selected according to the patient′s specific situation.
