摘　　要：目的 探讨大块复合树脂联合透明预成冠修复乳切牙的临床效果。方法 选取2019年10月—2020年12月山东省泰安市中医二院收治的幼儿乳切牙缺损者170例为研究对象。按照随机数表法分为两组,各85例。观察组实施Kavo声波手机下SonicFill大块复合树脂透明预成冠内注射处理,对照组则以3MZ350 XT通用纳米树脂对透明预填充治疗。比较两组治疗3个月后改良USPHS标准各项目评分、不同随访时间修复成功率、随访2年内出现的并发症、操作时间。结果 观察组治疗3个月后边缘完整性、台阶情况、色素沉着情况、牙龈状况、修复体与邻牙的邻接关系得分分别为(3.5±0.2)分、(3.3±0.3)分、(3.6±0.2)分、(3.4±0.2)分和(3.2±0.1)分,均显著高于对照组,差异有统计学意义(t=20.456、20.456、32.596、23.013、20.616,P<0.05)。治疗6个月后和治疗1年后,观察组修复成功率分别为98.8%、97.6%,显著高于对照组的85.9%、82.4%,差异有统计学意义(χ^(2)=10.078、11.046,P<0.05),随访2年后,观察组继发龋齿、破碎和(或)脱落、瘘管形成、慢性疼痛及牙龈炎等总发生率为3.5%,显著低于对照组的27.1%,差异有统计学意义(χ^(2)=18.162,P<0.05),观察组操作时间为(15.6±1.7)min,显著短于对照组操作时间的(28.5±3.6)min,差异有统计学意义(t=29.873,P<0.05)。结论 针对乳切牙缺损幼儿实施大块复合树脂联合透明预成冠治疗,能有效促进患牙美学指标及功能恢复,提高修复效果,且操作时间短,并发症少,值得临床推广。Objective To investigate the clinical effect of bulk composite resin combined with transparent prefabricated crowns in the restoration of deciduous incisors.Methods A total of 170 children with deciduous incisor defects who were admitted to Tai’an Second Hospital of Traditional Chinese Medicine from October 2019 to December 2020 were selected as the research objects.According to the random number table method,they were divided into two groups,each with 85 cases.The observation group underwent intracoronal injection of SonicFill bulk composite resin transparent preformed under the Kavo sonic mobile phone.The control group was treated with 3MZ350 XT universal nano-resin for transparent pre-filling.The scores of each item of the modified USPHS standard after 3 months of treatment,the repair success rates at different follow-up time,the complications occurred within 2 years of followup,and the operation time of the two groups were counted.Results After 3 months of treatment in the observation group,the scores of edge integrity,step condition,pigmentation condition,gingival condition and the adjacency relationship were(3.5±0.2) points,(3.3±0.3) points,(3.6±0.2) points,(3.4±0.2) points and(3.2±0.1) points were significantly higher than those in the control group,and the difference was statistically significant(t=20.456,20.456,32.596,23.013,20.616,P<0.05).After 6 months of treatment and 1 year after treatment,the repair success rates in the observation group were 98.8%,97.6%,which were significantly higher than those in the control group 85.9%,82.4%,and the difference was statistically significant(χ^(2)=10.078,11.046,P<0.05).During the 2-year follow-up,the total incidence of secondary caries,broken and/or shedding,fistula formation,chronic pain and gingivitis in the observation group 3.5% was significantly lower than 27.1% in the control group,and the difference was statistically significant(χ^(2)=18.162,P<0.05).The operation time of the observation group was(15.6±1.7) min,which was significantly shorter than
