数字化正畸正颌联合治疗骨性Ⅲ类患者1例并文献回顾

Digital orthodontics combined with orthognathic treatment for one case of skeletal classⅢand literature review

骨性Ⅲ类错[牙合]是一种以上下颌骨发育不调、咬合关系紊乱、前牙反[牙合]为特征的错颌畸形。其畸形因素更多源于颌骨,单纯通过正畸手段移动牙齿难以取得较好矫治效果,临床上常选择正畸-正颌联合治疗方式从根本上纠正颅颌面畸形。传统正畸-正颌联合治疗因其疗程长、治疗环节复杂,易出现偏差导致术后效果不佳、术后反[牙合]复发等不良影响。本文报道1例数字化技术辅助正畸-正颌联合治疗骨性Ⅲ类患者的案例,结合其治疗过程及治疗效果探讨数字化技术在正畸-正颌联合治疗中的应用并文献回顾。

Skeletal ClassⅢmalocclusion is a malocclusion deformity characterized by irregular development of the upper and lower jaws,disordered occlusal relationship,and anterior crossbite.The deformity factors are more derived from the jaws,and it is difficult to achieve better correction results by simply moving the teeth through orthodontic methods.Clinically,the combined orthodontic-orthognathic treatment is often used to fundamentally correct craniomaxillofacial deformities.Traditional orthodontic-orthognathic combined treatment is prone to easy deviations resulting in poor postoperative results,postoperative recurrence of malocclusion due to its long treatment course,and complicated treatment procedures.This article reports a case of digital technology-assisted orthodontics-orthognathic combined treatment of skeletal classⅢpatients,discusses the application of digital technology in orthodontic-orthognathic combined treatment,and reviews the literature based on the treatment process and therapeutic effect.
