摘　　要：目的观察氧化锆和纤维桩核冠修复牙体大面积缺损的临床疗效及对患者炎症损伤和咀嚼功能的影响。方法选取2020年7月至2023年5月周口市中医院收治的牙体大面积缺损患者80例作为研究对象进行回顾性研究。按治疗方式分组,接受氧化锆核冠修复作为研究组(40例),接受纤维桩核冠修复作为对照组(40例)。对比两组修复后1年的临床疗效、咀嚼功能、粉白美学效果、并发症。结果修复1年后,研究组相邻表面接触、表面质量、舒适度、边缘密合度合格率均高于对照组(P<0.05);两组咬合力、咀嚼效能均高于修复前,研究组高于对照组,两组混合程度数据(SDHue)值低于修复前,研究组低于对照组(P<0.05);研究组粉色美学指数(PES)、白色美学指数(WES)评分均高于对照组(P<0.05);研究组桩核松动脱落5.00%(2/40)、继发龋2.5%(1/40)、嵌塞5.00%(2/40)与对照组桩核松动脱落1.00%(1/40)、继发龋2.5%(1/40)、嵌塞5.00%(2/40)比较无差异(P>0.05)。结论氧化锆和纤维桩核冠修复用于牙体大面积缺损,氧化锆核冠修复的临床疗效更佳,不仅能减轻龈沟液炎症损伤程度,还能提高患者咀嚼功能和粉白美学效果,修复效果好。Objective To observe the clinical efficacy of zirconia and fiber post core crown in the restoration of large area tooth defect and the effect on inflammatory injury and masticatory function of patients.Methods A retrospective study was conducted on 80 patients with extensive dental defects admitted to Zhoukou Hospital of Traditional Chinese Medicine from July 2020 to May 2023.Divided by treatment method,the study group(40 cases)received zirconia core crown repair,while the control group(40 cases)received fiber post core crown repair.Compare the clinical efficacy,chewing function,whitening aesthetic effect,and complications between two groups after one year of repair.Results After one year of repair,the qualified rates of adjacent surface contact,surface quality,comfort,and edge fit in the study group were higher than those in the control group(P<0.05);The bite force and chewing efficiency of both groups were higher than before repair,with the study group higher than the control group.The SDHue value of the mixed degree data of the two groups was lower than before repair,and the study group was lower than the control group(P<0.05);The pink aesthetic index(PES)and white aesthetic index(WES)scores of the research group were higher than those of the control group(P<0.05);There was no significant difference(P>0.05)in the loosening and detachment rate of 5.00%(2/40),secondary caries rate of 2.5%(1/40),and impaction rate of 5.00%(2/40)between the research group and the control group(1.00%(1/40),secondary caries rate of 2.5%(1/40),and impaction rate of 5.00%(2/40)).Conclusions Zirconia and fiber post core crown repair for large area of dental defects,zirconia core crown repair has better clinical efficacy,not only can reduce the degree of gingival crevicular inflammation damage,but also can improve the masticatory function of patients and pink aesthetic effect,good repair effect.
