多根管纤维桩联合氧化锆全瓷冠修复治疗磨牙大面积牙体缺损患者的效果

Effects of multi-canal fiber posts combined with Zirconia all-ceramic crowns in treatment of patients with large molar defects

目的:观察多根管纤维桩联合氧化锆全瓷冠修复治疗磨牙大面积牙体缺损患者的效果。方法:选取2021年4月至2023年4月该院收治的104例磨牙大面积牙体缺损患者开展前瞻性研究,按照随机数字表法分为观察组与对照组各52例。对照组予以金属桩联合氧化锆全瓷冠修复治疗,观察组予以多根管纤维桩联合氧化锆全瓷冠修复治疗,比较两组修复成功率、治疗后美学效果评分和治疗前后牙周指标[牙龈出血指数(GBI)、菌斑指数(PLI)]水平。结果:观察组修复成功率为98.08%,明显高于对照组的82.69%,差异有统计学意义(P<0.05);治疗后6个月,观察组美学效果评分低于对照组,差异有统计学意义(P<0.05);治疗后6个月,两组GBI、PLI等牙周指标水平均低于治疗前,且观察组低于对照组,差异有统计学意义(P<0.05)。结论:多根管纤维桩联合氧化锆全瓷冠修复治疗磨牙大面积牙体缺损可提高修复成功率,降低美学效果评分和牙周指标水平,效果优于金属桩联合氧化锆全瓷冠修复治疗。

Objective:To observe effects of multi-canal fiber posts combined with Zirconia all-ceramic crowns in treatment of patients with large molar defects.Methods:The clinical data of 104 patients with large molar defects admitted to this hospital from April 2021 to April 2023 were selected for the prospective study.According to the random number table method,they were divided into observation group and control group,52 cases in each group.The control group was treated with metal post combined with Zirconia all-ceramic crown restoration,while the observation group was treated with multi-canal fiber post combined with Zirconia all-ceramic crown restoration.The success rate of restoration,the aesthetic effect score after the treatment,and the periodontal indexes[gingival bleeding index(GBI),plaque index(PLI)]before and after the treatment were compared between the two groups.Results:The success rate of restoration in the observation group was 98.08%,which was significantly higher than 82.69%in the control group,and the difference was statistically significant(P<0.05).Six months after the treatment,the aesthetic effect score of the observation group was lower than that of the control group,and the difference was statistically significant(P<0.05).Further,6 months after the treatment,the levels of periodontal indexes such as GBI and PLI in the two groups were lower than those before the treatment,those in the observation group were lower than those in the control group,and the differences were statistically significant(P<0.05).Conclusions:Multi-canal fiber posts combined with Zirconia all-ceramic crowns in the treatment of large molar defects can improve the success rate of restoration and reduce the aesthetic effect scores and the periodontal index levels.Moreover,it is superior to metal post combined with Zirconia all-ceramic crown restoration.
