摘　　要：目的观察肌功能训练器对乳牙期、替牙期错[牙合]畸形的治疗效果。方法27例错[牙合]畸形患者，乳牙列患者3例，均为Ⅱ类关系，其中Ⅲ度深覆[牙合]2例，1例伴Ⅲ度深覆盖。替牙列患者24例，其中Ⅰ类关系11例，Ⅱ类关系8例，Ⅲ类关系5例，均表现为前牙区拥挤，其中个别切牙反[牙合]4例，Ⅲ度深覆胎伴Ⅲ度深覆盖2例。均采用肌功能训练器治疗，根据年龄和错[牙合]畸形类型，选用相应INFANT、T4K、IgN训练器，要求患者日间戴用1h以上，晚间睡觉时间戴用，并按要求进行呼吸和吞咽等训练，每1．0～1．5个月复诊1次。结果6～10个月后，24例配合良好的患者，牙齿拥挤改善，深覆[牙合]、深覆盖获得完全纠正，面型改善。结论肌功能训练器治疗乳牙期、替牙期因不良习惯及口周肌功能异常导致的错[牙合]畸形是有效的，患者的良好配合是矫治成功的关键。Objective To clarify the effect of myofunetional treatment on primary and mixed dentition malocclusion.
