Oral habits should be of primary clinical concern to orthodontists because they may cause malocclusion, and/or interfere with treatment progress. Generally habit control should be achieved prior to correction of the malocclusion in an effort to remove any etiological factors in development and maintenance of the malocclusion. It is also important for the clinician to understand that habit-breaking treatment may require an extended treatment time because habits may have been present for long periods of time and may be related to underlying psychological problems. The present report documents the treatment of maxillary protrusion in a patient in which a thumb-sucking habit had persisted from infancy until almost age 12. Elimination of the habit was accomplished prior to correcting the malocclusion and for stability of the result. Orthodontic treatment consisted of extracting two maxillary premolars followed by full treatment with fixed appliances. Long-term postretention records show good stability of the corrected malocclusion.
口腔习惯应是正畸医生主要关注的临床问题，因为它们可能导致错牙合畸形，和/或干扰治疗进程。一般来说，在矫正错牙合畸形之前应实现习惯控制，以消除错牙合畸形发生和维持的任何病因。临床医生还应明白，破除习惯的治疗可能需要延长治疗时间，因为习惯可能已经存在很长时间，并且可能与潜在的心理问题有关。本报告记录了一名上颌前突患者的治疗情况，该患者从婴儿期一直持续到将近12岁都有吮拇指习惯。在矫正错牙合畸形之前消除了该习惯，以确保结果的稳定性。正畸治疗包括拔除两颗上颌前磨牙，然后用固定矫治器进行全面治疗。长期的保持后记录显示，矫正后的错牙合畸形具有良好的稳定性。
