摘　　要：目的探讨在正畸前戴用RW-splint是否可引导或确定下颌处于正中关系位,以期为后期诊断设计提供帮助。方法选择安氏Ⅱ类1分类错畸形患者20例,在固定矫治前进行RW-splint治疗,测量前牙覆盖量的变化。结果治疗前的前牙覆盖量为(6.792±0.795)mm,治疗后半年的前牙覆盖量为(7.720±0.930)mm,治疗前和治疗后半年前牙覆盖量差异有统计学意义(t=6.319,P<0.01),治疗后半年与治疗前前牙覆盖量变化值为(0.928±0.657)mm。结论正畸前戴用RW-splint可引导或确定下颌处于正中关系位,为后期诊断设计提供帮助。Objective To investigate whether the RW-splint could be used to guide or determine the CR position ofthe lower jaw so as to provide help for the later diagnostic design.Methods20classⅡⅠmalocclusion patients wererecruited in orthodontic department of Foshan Stomatological Hospital.They were treated by RW-splint for half a yearbefore orthodontic treatment.The overjet of anterior teeth were recorded before and after treatment.Results The overjet of anterior teeth was(6.792±0.795)mm before treatment and(7.720±0.930)mm after half a year??s treatment.Theoverjet of anterior teeth had significant difference(t=6.319,P<0.01).The overjet change of anterior teeth between before treatment and half year after treatment was(0.928±0.657)mm.Conclusion The RW-splint wearing before treatment can be used to guide or determine the mandible in the CR position.
