摘　　要：目的:对3D重建辅助制备咬合诱导功能矫治器治疗儿童替牙早期错牙合畸形的临床效果进行定性和定量评估。方法:于2015年3月-2018年3月采用病例抽样的方法抽取笔者医院替牙早期错牙合畸形患儿,采用临床随机对照试验的设计原理,将患者分为两组。以3D重建辅助制备咬合诱导功能矫治器治疗为试验组,以传统二维平面辅助制备咬合诱导功能矫治器治疗为对照组,治疗后对疗效进行定性定量评估。结果:试验组及对照组各40例患儿矫治术均实施成功,患儿均未发生术后不良反应,咬合功能恢复良好,除外1例患儿,其他患儿的面部形态满意度良好;试验组与对照组治疗后的前牙覆牙合、前牙覆盖、上牙弓宽度、下牙弓宽度、上牙弓拥挤度及下牙弓拥挤度比较差异均具有统计学意义(均P<0.05);患儿是否患有龋齿和牙周炎是3D重建辅助制备咬合诱导功能矫治器治疗儿童替牙早期错牙合畸形的影响因素(均P<0.05)。结论:3D重建辅助制备咬合诱导功能矫治器治疗儿童替牙早期错牙合畸形的临床效果较传统二维模式更好,患儿治愈后应注意龋齿和牙周炎的预防,以进一步巩固疗效。Objective To qualitatively and quantitatively evaluate the clinical effect of 3 D reconstruction assisted preparation of occlusal induction functional appliance for the treatment of early malocclusion of children’s teeth, and to provide a reference for the clinical application of three-dimensional reconstruction technology to treat children’s maxillofacial skeletal deformities.Methods From March 2015 to March 2018, a case sampling method was used to select children with early malocclusion of replacement teeth in our hospital. The design principle of clinical randomized controlled trials was used to prepare the treatment group of occlusion induction functional appliance with 3 D reconstruction. As the experimental group, the traditional twodimensional plane assisted preparation of the occlusal induction functional appliance treatment group as the control group, the efficacy of qualitative and quantitative evaluation after treatment. Results The treatment of 40 children in the experimental group and the control group was successfully implemented. None of the children had postoperative adverse reactions, and the occlusal function recovered well. The facial morphology satisfaction of the other children except one was good;the experimental group Compared with the control group, the anterior overbite, anterior tooth coverage, upper arch width, lower arch width, upper arch crowding degree and lower arch crowding degree were statistically different after treatment(all P<0.05).Whether the child suffers from dental caries and periodontitis is the influencing factor of 3 D reconstruction assisted preparation of occlusal induction functional appliance for the treatment of early malocclusion of children’s tooth replacement(all P<0.05).Conclusion The 3 D reconstruction-assisted preparation of occlusal-inducing functional appliances has a better clinical effect than the traditional two-dimensional model in the treatment of early malocclusion of children’s teeth. However, after the children are cured, attention should be
