推磨牙远移是一种有效的正畸技术,用于解决上颌或下颌牙齿的拥挤问题。通过将磨牙向后移动,可以为前牙创造更多的空间,从而减少拥挤,改善咬合关系。对于有双颌前突的患者,推磨牙远移也可以帮助矫正前突,减少面部突度,改善患者的侧貌。在推磨牙远移的过程中,支抗的作用至关重要。支抗是指在牙齿移动过程中,用来抵抗或控制其他牙齿移动的力量来源。在正畸治疗中,尤其是推磨牙远移时,有效的支抗能够确保目标牙齿按照预期的方向和程度移动,而不会引起不必要的副作用,如其他牙齿的不期望移动、咬合关系的变化等。本文对推磨牙向远中的支抗进行综述,提出各种支抗的不足和临床应用中的限制,为临床应用和技术改进提供参考依据。Molar distalization is an effective orthodontic technique used to solve the crowding problem of maxillary or mandibular teeth. By moving the molars backward, more space can be created for the anterior teeth, thereby reducing crowding and improving the occlusal relationship. For patients with bimaxillary protrusion, molar distalization can also help correct the protrusion, reduce facial protrusion, and improve the patient’s profile. In the process of molar distalization, the role of anchorage is crucial. Anchorage refers to the source of force used to resist or control the movement of other teeth during tooth movement. In orthodontic treatment, especially when molar distalization, effective anchorage can ensure that the target teeth move in the expected direction and degree without causing unnecessary side effects, such as the unexpected movement of other teeth and changes in the occlusal relationship. This article reviews the anchorage for molar distalization, puts forward the shortcomings of various anchorage and the limitations in clinical application, and provides a reference for clinical application and technical improvement.
