摘要
目的探讨口周肌力在下颌支抗控制中的应用。方法临床上应用多曲不锈钢丝唇挡配合方丝弓固定矫治器对13例恒牙早期轻度牙列拥挤患者进行矫治,分析治疗前后支抗磨牙位置变化,观察支抗丧失情况。结果利用口周肌力可以对支抗磨牙进行控制,防止支抗丧失。结论可以在矫治过程中采用多曲唇挡来增强支抗。而且多曲唇挡制作简单,患者戴用舒适、隐蔽,容易获得患者的配合。
Objective To study the application of perioral muscular forces in the mandibular anchorage control in order to search a new approach of increasing the intro-oral anchorage.Methods Thirteen patients with mild crowding in permanent dentition were treated with edgewise appliance and multiloop lip bumper.The movement of anchorage molar in before and after treatment was recorded so as to observe the loss of anchorage.Results The loss of anchorage could be avoided through the application of perioral muscular forces.Conclusions The multiloop lip bumper can be applied to increase anchorage,which is easily fabricated,comfortable and hidden for patients.
