[摘 要]目的 探究在小儿替牙期牙齿畸形矫正治疗中应用直丝弓矫正技术的效果。方法 选取2023年1月-2024年1月于我院接受替牙期牙齿畸形矫正治疗的100例患儿为研究对象，采用随机数字表法分为对照组和观察组，各50例。对照组采用方丝弓矫正技术，观察组采用直丝弓矫正技术，比较两组临床疗效、咀嚼功能、吞咽功能、语言功能及不良反应发生情况。结果 观察组治疗总有效率为96.00%，高于对照组的80.00%，差异有统计学意义(P<0.05)；两组矫治后咀嚼效率、咬合力均优于矫治前，且观察组优于对照组，差异有统计学意义(P<0.05)；两组矫治后吞咽功能、语言功能评分均高于矫治前，且观察组高于对照组，差异有统计学意义(P<0.05)；观察组不良反应发生率为4.00%，低于对照组的18.00%，差异有统计学意义(P<0.05)。结论 在小儿替牙期牙齿畸形矫正治疗中应用直丝弓矫正技术可有效提升患儿咀嚼效率和咬合力，改善吞咽和语言功能，降低不良反应发生几率，提高矫治效果。
