摘　　要：目的 比较后牙缺损患者根管治疗后应用树脂超瓷嵌体与铸瓷高嵌体的修复效果。方法 选择2019年2月至2022年3月镇江市口腔医院收治的198例(患牙235颗)后牙缺损患者,按随机数字表法分为研究组(n=99,患牙116颗)与对照组(n=99,患牙119颗)。2组均接受根管治疗术。对照组术后应用树脂超瓷嵌体修复,研究组术后应用铸瓷高嵌体修复。对比2组修复情况、牙周指数、并发症及修复效果满意度。结果 研究组修复成功率(93.10%)高于对照组(84.87%),差异有统计学意义(P<0.05)。研究组修复失败率(5.17%)低于对照组(12.61%),差异有统计学意义(P<0.05)。2组修复时间、修复缺陷率比较,差异无统计学意义(P>0.05)。修复后12个月,2组龈沟出血指数(SBI)、牙龈乳头指数(PIS)、菌斑指数(PLI)均降低(P<0.05),且研究组更低(P<0.05)。2组并发症总发生率比较,差异无统计学意义(P>0.05)。研究组修复效果满意度(94.83%)高于对照组(81.51%),差异有统计学意义(P<0.05)。结论 后牙缺损患者根管治疗后应用铸瓷高嵌体的修复效果较应用树脂超瓷嵌体更佳,可提高患者修复满意度,促进牙周健康,且安全可靠。Objective To compare the repair effects of resin super-porcelain inlays and cast porcelain onlays on posterior tooth defects after root canal treatment.Methods A total of 198 patients with posterior tooth defects(235 teeth)who were admitted to Zhenjiang Stomatological Hospital from February 2019 to March 2022 were selected and divided into study group(99 cases,116 teeth)and control group(99 cases,119 teeth)according to random number table method.After root canal therapy,the control group was repaired with resin super-porcelain inlays,and the study group was repaired with cast porcelain onlays.The repair result,periodontal index,complications and satisfaction were compared between the two groups.Results The success rate of repair in the study group was higher than that in the control group(93.10%vs.84.87%,P<0.05).The failure rate of repair in the study group was lower than that in the control group(5.17%vs.12.61%,P<0.05).There was no significant difference in the repair time or defect rate between the two groups(P>0.05).Twelve months after repair,sulcus bleeding index(SBI),gingival papilla index(PIS)and plaque index(PLI)were decreased in both groups(P<0.05),and these indexes in the study group were lower than those in the control group(P<0.05).There was no significant difference in the total incidence of complications between the two groups(P>0.05).The satisfaction rate of repair in the study group was higher than that in the control group(94.83%vs.81.51%,P<0.05).Conclusion Compared with the resin super-porcelain inlays after root canal treatment,the cast porcelain onlays has better repair effect.It can improve the satisfaction of patients and promote periodontal health with high safety and reliability.
