The aim of this study is to evaluate the efficacy of a single piece bird wing osteotectomy segment during anterior maxillary osteotomy (AMO) markedly reduces the duration of the surgery by nearly one-half of the time during bone removal with the conventional method thereby reducing the kinking effect to the palatal pedicle and gives good perfusion to the anterior segment.
This study was conducted at Karpaga Vinayaga Institute of Dental Sciences composing of 20 patients in which male: female ratio was 8:12, with a mean age of 25-30 years. This bird wing segment technique is performed following presurgical orthodontics under the guidance of clinical assessment of the gummy smile with an incisal show when the lip is at repose (vertical maxillary excess), especially for the calculated amount of superior repositioning. It is calculated by subtracting 2 mm from the total amount of an incisor show when the lip is at repose. The normal incisal show when the lip is at repose is 2 mm. After conventional primary AMO cut was performed, the precise calculated.
All our cases were tested positive for pulp vitality, no relapse, and minimal edema and with no changes in the bite or dentoalveolar relation followed until 1 year postoperatively indicating a good perfusion to the anterior segment and all the patients were satisfied esthetically and free of complaints.
This simple technique allows the precise amount of calculated bone removal in a single piece from the nasal floor markedly reduces the duration of the surgery by nearly one-half of the time during bone removal with the conventional method there by reducing the kinking effect to the palatal pedicle and maintains good perfusion.
本研究的目的是评估在上颌前部截骨术（AMO）期间采用单片鸟翼状截骨段的疗效，该方法可使手术时间显著缩短，几乎减少至传统方法去骨时间的一半，从而减少对上颌蒂的扭结效应，并为前部节段提供良好的血供。
本研究在卡尔帕加·维奈亚加牙科学院进行，共有20例患者，男女比例为8:12，平均年龄为25至30岁。该鸟翼状截骨段技术是在术前正畸治疗后，根据静息位时露龈笑（垂直上颌骨过长）的临床评估，尤其是对于计算得出的上颌骨上移量进行的。计算方法是从静息位时切牙暴露的总量中减去2毫米。静息位时正常的切牙暴露量为2毫米。在进行常规的初次AMO截骨后，进行精确计算。
我们所有的病例牙髓活力测试均为阳性，无复发，水肿轻微，术后1年随访期间咬合或牙牙槽关系无变化，表明前部节段血供良好，所有患者在美观方面均满意且无不适主诉。
这种简单的技术能够精确计算出从鼻底一次性去除的骨量，可使手术时间显著缩短，几乎减少至传统方法去骨时间的一半，从而减少对上颌蒂的扭结效应，并保持良好的血供。
