Abstract

Class II Division 1 malocclusion is characterized by maxillary incisor protrusion and excessive overjet, leading to common esthetic concerns among patients. Clinically, determining between extraction and nonextraction is a complicated treatment decision, especially in patients with borderline diagnoses. This case report describes the treatment of an adult borderline case with Class II Division 1 malocclusion and protruding maxillary incisors. To ensure esthetic prognosis, the virtual treatment goal for maxillary incisors was set on the basis of esthetic criteria. In addition, a 3-dimensional evaluation was conducted to acquire comprehensive information on the arch volume for scientific treatment decision-making. This patient received a nonextraction treatment involving maxillary dentition sequential distalization and proper dental expansion aimed to retract the protruding maxillary incisors to the ideal esthetic position. The treatment was successfully conducted using clear aligners and mini-implants. Ultimately, harmonious dentofacial esthetics and ideal functional occlusion were achieved after 33 months of treatment and maintained after 2 years of retention.

使用透明矫治器和微型种植体对一名 II 类 1 型错颌畸形成人进行上颌牙序贯远端矫治
二类一区错颌畸形的特点是上颌切牙前突和过度后凸,导致患者普遍存在美观问题。在临床上,决定拔牙还是不拔牙是一个复杂的治疗决策,尤其是对于诊断为边缘性的患者。本病例报告描述了对一名患有二类一区错颌畸形和上颌切牙突出的成人边缘病例的治疗。为了确保美学预后,我们根据美学标准设定了上颌切牙的虚拟治疗目标。此外,还进行了三维评估,以获得牙弓容积的全面信息,从而做出科学的治疗决策。该患者接受了非拔牙治疗,包括上颌牙序远端化和适当的牙齿扩张,目的是将突出的上颌门牙牵引到理想的美学位置。使用透明矫治器和微型种植体成功完成了治疗。最终,经过33个月的治疗,患者获得了和谐的颌面美学效果和理想的功能性咬合,并在2年的保持期后得以维持。
