Although headgear is rarely used in adult patients, its use in adults is mainly for anchorage control. In the current case report, a 24-year-old patient had a skeletal Class I relationship with a Class II tendency, brachyfacial pattern, significant facial asymmetry, and dental 3/4 cusp Class II molar and canine relationships on both sides. The patient declined surgery, and facial asymmetry was not his concern. The final treatment goal was to achieve a stable Class I dental relationship and normal occlusion without significantly compromising the patient's profile. The patient was compliant with the use of cervical-pull headgear after he refused the options of orthodontic-orthognathic combined treatment, maxillary premolar extraction, or temporary skeletal anchorage mini-implants. A 5-mm maxillary arch distal movement was accomplished without significant distal tipping of the molar crowns. The active treatment duration was 31 months. Proper overbite and overjet, balanced occlusion, and an acceptable facial profile were achieved. The treatment results inspire reconsideration of the possibility of using headgear in dental Class II correction in adult patients.
尽管头帽很少用于成年患者,但其在成人中的使用主要是为了控制支抗。在本病例报告中,一名24岁的患者为骨骼I类关系,有II类倾向,短面型,明显的面部不对称,双侧牙齿为3/4尖对尖II类磨牙和尖牙关系。患者拒绝手术,且不关心面部不对称问题。最终的治疗目标是在不显著影响患者侧貌的情况下,实现稳定的I类牙关系和正常咬合。在患者拒绝正畸-正颌联合治疗、拔除上颌前磨牙或临时骨支抗微型种植体等方案后,他配合使用了颈牵引头帽。上颌牙弓远中移动了5毫米,磨牙冠没有明显的远中倾斜。积极治疗持续时间为31个月。实现了适当的覆合覆盖、平衡的咬合以及可接受的面部侧貌。治疗结果促使人们重新考虑在成年患者II类错牙合矫治中使用头帽的可能性。
