The patient with a Class II malocclusion, proclination, or moderate crowding of the mandibular anterior teeth, and a moderate-to-low mandibular plane angle is a treatment-planning challenge. The records of 3 patients are presented. For 2 of them, extraction treatment was used to resolve the Class II malocclusion problem. Each of these patients was treated with the removal of maxillary first premolars and mandibular second premolars. The third patient was treated with Class II elastics without extractions. The clinician must weigh the pros and cons of each approach and decide which approach will give the patient the best long-term benefit.
对于安氏 II 类错牙合、前牙前倾或下颌前牙中度拥挤、下颌平面角中低的患者，治疗计划颇具挑战性。现介绍 3 例患者的记录。其中 2 例采用拔牙治疗解决 II 类错牙合问题。这 2 例患者均接受了上颌第一前磨牙和下颌第二前磨牙的拔除。第 3 例患者采用了 II 类橡皮圈非拔牙治疗。临床医生必须权衡每种方法的利弊，并决定哪种方法能为患者带来最佳的长期获益。
