Bottom Line: 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.The normal incisal show when the lip is at repose is 2 mm.After conventional primary AMO cut was performed, the precise calculated.

ABSTRACT

Aim: 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.

Materials and methods: 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.

Results: 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.

Conclusion: 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.

Figure 1: 10 mm of incisal show when lip is at repose

Mentions: For example, [Figure 1] in a case where the incisal show is revealed as 10 mm when the lip is at repose, whereas the preferred amount of an incisal show is only 2 mm. This is achieved by superior repositioning of the premaxilla by 8 mm [Figure 2]. The clinically calculated 8 mm [Figure 3] to superiorly repositioning of the dentoalveolar segment, in a predetermined position with perfect alignment to the basal bone in end-to-end contact thereby providing maximum stability with minimum hardware of 2-hole plate one on either side of the pyriform rim [Figure 4].
