摘　　要：目的观察瓷嵌体在青少年恒牙大面积缺损修复时的临床疗效。方法选取2016年1月至2019年1月银川市口腔医院儿童口腔科治疗的青少年恒牙牙体大面积缺损,且牙髓活力正常的患牙84颗,根据治疗的不同分为两组,研究组和对照组各42颗,研究组应用瓷嵌体修复,对照组应用复合树脂充填修复。采用改良美国公共卫生服务(USPHS)标准评价修复后6个月、12个月的临床疗效。结果研究组治疗6个月后,各项指标均达到了A级标准,对照组各项指标A级标准在90%以上,两组修复效果在边缘密合性、术后敏感性、继发龋、修复体折裂、修复体脱落方面的差异均无统计学意义(P均>0.05)。研究组在边缘着色方面优于对照组(P<0.05);治疗12个月后,研究组各项指标A级标准的占比均在90%以上,对照组A级标准的占比亦80%以上。两组修复效果在继发龋、修复体折裂、修复体脱落方面的差异无统计学意义(P均>0.05)。研究组在边缘密合性、边缘着色、术后敏感性方面均优于对照组(P均<0.05)。结论瓷嵌体与复合树脂修复青少年恒牙大面积牙体缺损疗效均较好,瓷嵌体更有效地恢复恒牙的牙体形态,提高咀嚼效率,降低继发龋,有利于患者的修复。Objective To observe the clinical effect of ceramic inlays or onlays in repairing the large defects of permanent teeth in adolescents.Methods 84 adolescent permanent teeth with large dental defects,and normal pulp vitality were selected randomly in the Department of Pediatric Dentistry of Yinchuan Stomatology Hospital from January 2016 to January 2019.They were divided into 2 groups according to the random number method,42 cases each in the study group and the control group,and patients in the study group ceramic inlay or onlay was used,and the control group was treated with composite resin.The two groups were used to evaluate the clinical efficacy of 6 months and 12 months after restoration by United States Public Health Service(USPHS)criteria.Results After 6 months of treatment,all the indexes in the study group reached the A-level standard,while the indexes in the control group were above 90%.There was no statistical significance in the effect of the two groups in the aspects of marginal adaptation,post-operative sensitivity,secondary caries,prosthesis fracture and prosthesis fall off(P all>0.05).The marginal discoloration of the study group was better than that of the control group,and the difference was statistically significant(P<0.05).After 12 months of treatment,the proportion of grade A standards in the study group was above 90%,and the proportion of grade A standards in the control group was also above 80%.There was no significant difference between the two groups in secondary caries,fracture of prosthesis and shedding of prosthesis(P all>0.05).The study group was superior to the control group in the aspects of marginal adaptation,marginal discoloration and postoperative sensitivity,with statistical significance(P all<0.05).Conclusion Ceramic inlays or onlays and composite resin are both effective in repairing large defect of permanent teeth in adolescents.However,ceramic inlays or onlays are more effective in repairing permanent teeth shape,improving chewing efficiency and reducing secondary caries,whi
