摘要/Abstract

摘要： 本文报道了1例采用改良牙周辅助加速成骨正畸(periodontally accelerated osteogenic orthodontics, PAOO)技术辅助治疗骨性Ⅱ类错牙合畸形的临床病例。本病例在正颌手术前正畸去代偿阶段,实施改良PAOO术式,包括保留龈乳头切口设计、全厚瓣翻瓣术、超声骨刀牙根间骨皮质切开术、无胶原屏障膜覆盖的骨增量技术(仅使用骨移植材料)以及创新缝合方法。术后24个月的随访显示,术区唇侧骨板厚度显著增加,角化龈宽度明显改善,且长期疗效稳定,未出现显著牙龈退缩或重度牙周组织炎症反应。该改良术式在保证治疗效果的同时,有效降低了手术创伤及相关并发症风险。

Abstract: This article reports a clinical case of skeletal Class Ⅱ malocclusion treated with modified periodontally accelerated osteogenic orthodontics (PAOO). During the presurgical orthodontic decompensation phase, the modified PAOO technique was performed, featuring a papilla-preserving incision design, full-thickness flap elevation, piezocision-assisted interradicular corticotomy, bone augmentation without collagen barrier membrane (using bone graft material alone), and an innovative suturing method. A 24-month follow-up demonstrated significant increases in labial bone plate thickness and keratinized gingiva width at the surgical site, with stable long-term outcomes and no notable gingival recession or severe periodontal inflammatory reactions. The modified protocol effectively reduced surgical trauma and complication risks while ensuring therapeutic efficacy.

Key words: periodontally accelerated osteogenic orthodontics, corticotomy, alveolar bone argumentation, combined orthodontic-orthognathic treatment, skeletal class Ⅱ malocclusion
