Extractions in orthodontics remains a relatively controversial area. It is not possible to treat all malocclusions without taking out any teeth. The factors which affect the decision to extract include the patient's medical history, the attitude to treatment, oral hygiene, caries rates and the quality of teeth. Extractions of specific teeth are required in the various presentations of malocclusion. In some situations careful timing of extractions may result in spontaneous correction of the malocclusion.
正畸拔牙仍然是一个颇具争议的领域。不拔除任何牙齿就治疗所有错牙合畸形是不可能的。影响拔牙决策的因素包括患者的病史、对治疗的态度、口腔卫生、龋齿发生率和牙齿质量。在各种错牙合畸形表现中都需要拔除特定的牙齿。在某些情况下，仔细安排拔牙时机可能会使错牙合畸形自行矫正。
