This case report describes an orthodontic treatment using clear aligners in a patient with Class II malocclusion associated with a deep bite. A 16-year-old patient with skeletal Class II malocclusion presented with a retrognathic profile, a deep bite of 7 mm, deep curve of Spee, proclined incisors, spacing, an excess Bolton discrepancy in the mandible, lower midline shift 2 mm to the right, and long clinical crowns. The patient preferred aligners over traditional fixed orthodontic appliances. The treatment objectives were achieved in 2.2 years, and the patient was pleased with the aesthetic and treatment outcomes. Using aligners along with proper auxiliaries and attachments is an effective method of addressing orthodontic difficulties, such as Class II complicated with deep bites in a reasonable time. Further, clear aligners offer less pain, better oral hygiene, and more aesthetics comparable to that of conventional fixed orthodontic appliances.
本病例报告描述了一名安氏II类错牙合伴深覆牙合患者使用透明矫治器的正畸治疗过程。一名16岁的安氏II类骨性错牙合患者，面型后缩，深覆牙合7毫米，司皮曲线过深，切牙前倾，牙间隙，下颌Bolton指数不调，下中线右偏2毫米，临床冠长。与传统固定正畸矫治器相比，该患者更喜欢使用透明矫治器。治疗目标在2.2年内实现，患者对美观效果和治疗结果感到满意。在合理的时间内，使用透明矫治器并配合适当的辅助装置和附件是解决正畸难题（如II类错牙合伴深覆牙合）的有效方法。此外，与传统固定正畸矫治器相比，透明矫治器疼痛更少、口腔卫生更好且美观性更高。
