摘　　要：骨性Ⅱ类错(牙合)畸形特征为上颌前突、下颌后缩或两者兼具,且多伴有垂直向关系异常,治疗复杂,成年患者常需正畸正颌联合治疗。无托槽隐形矫治技术逐渐应用于复杂正畸治疗,而目前国内外针对无托槽隐形矫治技术在正颌手术方面的应用案例较少。本文作者报道1例采用无托槽隐形矫治联合正颌手术治疗骨性Ⅱ类高角错(牙合)畸形的患者,分析该治疗方法的临床疗效,以期为临床提供参考。正畸治疗前分次拔除阻生智齿18、28、38和48及正畸牙15、25、34和44,使用无托槽隐形矫治器进行术前正畸,矢状向建立尖牙及磨牙超完全远中关系,前牙覆盖13~14 mm,水平向匹配上下颌牙弓形态;正颌手术术式为上颌Le FortⅠ型截骨术、双侧下颌骨矢状劈开术(BSSRO)及颏成形术;术后精细调整咬合。患者术后上下颌骨关系恢复正常,上牙槽座点-鼻根点-下牙槽座点角(ANB)由12.3°改善为4.7°;尖牙和磨牙达到中性关系,前牙覆(牙合)、覆盖正常;牙根平行度良好,无明显牙根吸收;面部软组织侧貌显著改善,面突角(N-Sn-Pg)由143.9°改善为162.8°。术后1年疗效稳定。无托槽隐形矫治技术可以高效完成复杂病例的正畸正颌联合治疗,与固定矫治器相比,该技术更有利于患者对美观的需求及牙周健康的维护。Skeletal classⅡmalocclusion is characterized by maxillary protrusion,mandibular retrognathia,or a combination of both,and often accompanied by vertical dimensional discrepancies;treatment is complex,and combined orthodontic-orthognathic surgery is needed for the adult patients.Clear aligner therapy has gradually been applied in complex orthodontic cases.However,limited cases have been reported domestically and internationally regarding the application of clear aligner therapy combined with orthognathic surgery.This article presented a case of a patient with skeletal classⅡhigh-angle malocclusion treated with the combined therapy and analyzed the clinical efficacy of the treatment appraoch to provide reference for the clinical practice.Extraction of impacted wisdom teeth 18,28,38,and 48,as well as orthodontic teeth 15,25,34,and 44,was performed in stages before orthodontic treatment.Clear aligner therapy was used for preoperative orthodontics.In sagittal plane,a super-complete classⅡcanine and molar relationship and a 13-14 mm overjet of the anterior teeth were established.The maxillary and mandibular arch morphology was matched horizontally.The orthognathic surgery included maxillary LeFortⅠosteotomy,bilateral sagittal split ramus osteotomy(BSSRO)and chinplasty.Fine occlusal adjustment was conducted after operation.After treatment,the skeletal relationship between upper and lower jaw was corrected to normal;subspinale-nasion-supramental angle(ANB)was improved from 12.3°to 4.7°;the patient established the classⅠcanine and molar relationship,with normal overjet and overbite;root parallelism was good and there was no obvious root resorption;the facial soft tissue profile was significantly improved,and nasion-subnasale-pogonion angle(N-Sn-Pg)was improved from 143.9°to 162.8°.The curative effect was stable 1 year after operation.Clear aligner therapy can efficiently complete combined orthodontic and orthodontic surgery in the complex cases.Compared with the fixed appliance,it is more beneficial to the pa
