摘　　要：目的:探讨保留邻面壁髓腔固位部分冠修复对恒磨牙斜裂的修复效果。方法:选取2017年10月-2018年10月在笔者医院就诊的恒磨牙斜裂患者72例为研究对象。按照随机数字法及患者意愿将患者分为铸瓷嵌体组和聚合瓷嵌体组,每组36例。根据不同修复方式将两组患者分别分为3个亚组,采用髓腔固位冠修复的髓腔固位冠组,采用髓腔固位高嵌体修复的髓腔固位高嵌体组及采用保留邻面壁髓腔固位部分冠修复的保留邻面壁的髓腔固位部分冠组,每组12例。随访1年,对患者进行临床效果、不良反应及满意度调查。结果:在同种修复方式下,聚合瓷修复材料的总有效率、总满意度均显著优于铸瓷修复材料,总不良反应率显著低于铸瓷修复材料,差异有统计学意义(P<0.05);在同种修复材料下,保留邻面壁的髓腔固位部分冠的总有效率、总满意度均显著优于髓腔固位冠、髓腔固位高嵌体修复方式,总不良反应率显著低于髓腔固位冠、髓腔固位高嵌体修复方式,差异有统计学意义(P<0.05)。结论:聚合瓷材料在恒磨牙斜裂修复中更具有优势,保留邻面壁髓腔固位部分冠修复方式对恒磨牙斜裂具有良好的修复效果,值得临床进一步推广应用。Objective To observe the effect of endo-partial crown restoration with adjacent wall retaining on the restoration of the oblique fracture of permanent molars.Methods 72 patients with oblique fracture of permanent molars who treated in our hospital from October 2017 to October 2018 were selected.According to the random number method and the patient’s wishes,the patients were divided into the cast porcelain inlay group(n=36)and the polymeric porcelain inlay group(n=36).According to different repair methods,the patients were divided into three subgroups,including the endocrown group(n=12),endo-onlays group(n=12)and endo-partial crown restoration with adjacent wall retaining group(n=12).The patients were followed up for one year,and the patients were evaluated for clinical effect and investigate adverse reaction and satisfaction.Results Under the same repair method,the total effective rate and total satisfaction of the polymeric porcelain repair material were significantly better than those of the cast porcelain repair material,the total adverse reaction rate was significantly lower than those of cast porcelain repair material,and the difference was statistically significant(P<0.05).Under the same repair material,the total effective rate and total satisfaction of endo-partial crown restoration with adjacent wall retaining group were significantly better than the endocrown group and endo-onlays group,the total adverse reaction rate of endo-partial crown restoration with adjacent wall retaining group were significantly lower than the endocrown group and endo-onlays group,and the difference was statistically significant(P<0.05).Conclusion The polymeric porcelain repair material has more advantages on the restoration of the oblique fracture of permanent molars.The method of endo-partial crown restoration with adjacent wall retaining has a good effect on the restoration of the oblique fracture of permanent molars,which is worthy of further clinical application.
