摘 要：在儿童中牙冠冠折发生率非常高，断冠粘接治疗方式属于一种过渡性修复方式，为了观察该方式的临床疗效，文章使用实验的方法对其进行分析。选择医院内符合条件的96位患者作为研究对象，将其分为两组，一组为实验组，使用断冠粘接方式进行治疗，另一组为对照组，使用复合树脂直接修复方式治疗;然后在不同术后时间对两组进行复诊，考察两组的断冠保存率、美学修复效果和患者满意度。实验结果表明，实验组的断冠保存率、美学修复效果和患者满意度均高于对照组，且随着时间的延长，两组的断冠保存率和患者满意度处于不断降低趋势。于是可以得出结论：相比于复合树脂直接修复治疗方式，文章使用的恒前牙冠折自体断冠粘接治疗方式的临床疗效更好。

Abstract：The incidence of crown fractures in children is very high. The treatment of broken crowns is a transitional restoration method. In order to observe the clinical effects of this method， the paper uses experimental methods to analyze it. Select 96 eligible patients in the hospital as the research objects， divide them into two groups， one group is the experimental group， treated with broken crown bonding method， and the other group is the control group， treated with composite resin direct repair method; then the two groups were reviewed at different postoperative time to investigate the preservation rate of broken crowns， the aesthetic repair effect and patient satisfaction of the two groups. The experimental results showed that the preservation rate， aesthetic repair effect and patient satisfaction of the experimental group were higher than those of the control group， and as time went by， the preservation rate and patient satisfaction of the two groups were in a decreasing trend. Therefore， it can be concluded that， compared with the direct restoration treatment of composite resin， the permanent anterior tooth crown fracture autogenous broken crown adhesive treatment method used in this paper has better clinical effect.

牙冠折断属于口腔中常见的一种疾病，尤其在儿童中的发生率比较高，有研究数据表明，牙冠折断在儿童全部前牙外伤中占据一半的比例，所以有必要提高牙冠折断的治疗效果[1]。对于儿童来讲，由于牙根没有发育完全，而且颌面部发育也不稳定，所以并不能像成人一样使用永久修复治疗方式[2]。复合树脂直接治疗方式在临床实验中发现，虽然该方式能够为恒前牙冠折进行治疗，但是这种方式会影响到治疗美观度，而且脱落率还比较高[3]。所以经过不断的研究之后，发现粘接技术能够应用到断冠治疗中，通过使用自体断冠进行粘接治疗，能够保障断冠牙颜色的一致性，有助于提高牙齿修复效果的美观程度[4]。……
