【摘 要】目的 探究FR-Ⅲ型功能矫治器在前牙反合患儿中的应用效果。方法 选取2020年1月-2023年1月我院收治的60例前牙反合患儿为研究对象，以随机数字表法分为对照组和试验组，每组30例。对照组采用直丝弓固定矫治器治疗，试验组采用FR-Ⅲ型功能矫治器佩戴治疗，比较两组临床疗效、头影测量结果及儿童行为评定量表(CBCL)评分。结果 试验组治疗总有效率为96.67%，高于对照组的66.67%，差异有统计学意义(P<0.05)；试验组治疗后SNA角、SNB角大于对照组，ANB角、U1-SN角小于对照组，差异有统计学意义(P<0.05)；试验组治疗后CBCL评分低于对照组，差异有统计学意义(P<0.05)。结论 相比于常规直丝弓固定矫治器，FR-Ⅲ型功能矫治器治疗儿童前牙反合的效果更佳，可有效改善患儿的面部形态及心理行为问题，值得临床应用。
