纳米复合树脂联合透明预成冠修复上颌乳切牙的临床效果

探讨纳米复合树脂联合透明预成冠修复上颌乳切牙的临床效果。方法 选取2021年6月- 2022年6月于我院接受口腔修复的85例患儿作为研究对象，利用随机数字表法分为对照组（n =42）和观察 组（n =43）。对照组采用纳米复合树脂充填，观察组采用纳米复合树脂联合透明预成冠美学修复，比 较两组修复成功率、美学指标及口腔功能。结果 两组修复后3个月修复成功率比较，差异无统计学意 义（P ＞0.05）；观察组修复后6、12个月修复成功率高于对照组（P ＜0.05）；观察组修复后3、6、12个月 红白美学指标和面部美学指标评分均高于对照组（P＜0.05）；观察组修复后美观、咀嚼及语言评分均高于 对照组（P ＜0.05）。结论 纳米复合树脂联合透明预成冠修复上颌乳切牙的临床效果良好,能实现较好的修 复效果和美学价值，有效改善患者的口腔功能。

Clinical Effect of Nano-composite Resin Combined with Transparent Preformed Crown in Repairing Maxillary Deciduous Incisors

To investigate the clinical effect of nano-composite resin combined with transparent preformed crown in the repair of maxillary deciduous incisors. Methods A total of 85 children who received oral repair in our hospital from June 2021 to June 2022 were selected as the research objects. They were divided into control group (n =42) and observation group (n =43) by random number table method. The control group was filled with nano-composite resin, and the observation group was treated with nano-composite resin combined with transparent preformed crown aesthetic restoration. The success rate of repair, aesthetic indicators and oral function were compared between the two groups. Results There was no significant difference in the success rate of repair between the two groups at 3 months after repair (P >0.05). The success rate of repair in the observation group was higher than that in the control group at 6 and 12 months after repair (P <0.05). The pink and white esthetic scores and facial aesthetic indexes in the observation group were higher than those in the control group at 3, 6 and 12 months after repair (P <0.05). The scores of aesthetics, masticatory function and language in the observation group were higher than those in the control group (P <0.05). Conclusion The clinical effect of nano-composite resin combined with transparent preformed crown in the repair of maxillary deciduous incisors is good, which can achieve better repair effect and aesthetic value, and effectively improve the oral function of pa tients.
