Vertical maxillary excess is associated with gummy smile, incompetent lip,  bimaxillary proclination, Angle’s class-I or class-II malocclusion with or without retogenia. After proper evaluation preoperative orthodontic treatment was performed in every cases and superior repositioning of the maxilla by Le Fort-I osteotomy is presented. Three patients with maxillary excess associated with retrogenia or microgenia were treated with this technique in combination with genioplasty. The maxillary segment was repositioned a maximum of 7.0 mm superiorly at point A. The mandible autorotated anterosuperiorly to achieve sound occlusion. Point B moved 1.0–3.0 mm anteriorly and 5.0–8.0 mm superiorly. The pogonion moved 4.0 mm anteriorly in a case done without genioplasty and the pogonion moved maximum 8.0mm in case done in combination with genioplasty. All patients obtained sound occlusion and a good profile after the operation. Almost no skeletal relapse was observed during 3 years of postoperative follow-up. Amount of gingiva showing during smile was ranges from 5.0mm –7.0mm which was 0-2.0mm after superior repositioning of the maxilla. Ban J Orthod & Dentofac Orthop, April 2016; Vol-6 (1-2), P.1-5

Gummy Smile

Introduction: In cases with gummy smile or asymmetry of the maxilla, superior repositioning of the maxilla is required. If superior repositioning by a Le Fort I osteotomy alone is difficult, a horseshoe Le Fort I osteotomy can be used. Presentation of cases: Case 1: A 24-year-old Japanese woman patient presented with a gummy smile and an open bite. After we performed a horseshoe Le Fort I osteotomy, the maxillary segment was repositioned superiorly 3.0 mm at upper tooth number 1 (U1) and 5.0 mm at upper tooth number 6 (U6). Case 2: A 21-year-old Japanese man presented with severe facial asymmetry. After we performed a unilateral modified horseshoe Le Fort I osteotomy, the maxillary segment was superiorly repositioned 6.0 mm at the right U6. Discussion: This procedure eliminated the risk of intraoperative bleeding because it was unnecessary to remove bones around the descending palatine artery, and it was possible to maintain the chamber size of the nasal cavities. Conclusion: The horseshoe Le Fort I osteotomy is a reliable technique for cases with severe gummy smile or asymmetry of the maxilla.

The Class I skeletal deformity associated with vertical maxillary excess is a rare condition reported in the literature. Surgical impaction allows the correction of the long face and gummy smile. Objective: This case report aimed to evaluate the positioning of the condyle after Le Fort I osteotomy associated with mandibular selfrotation. Case report: The patient underwent orthognathic surgery for the correction of maxillary vertical excess. Tomography studies were performed to evaluate the initial and final position of the condyle. The patient improved mastication, breathing and phonetics, with esthetic benefit. Conclusion: After the Le Fort I osteotomy and mandibular self-rotation, the condyle remained stable occupying a new anterior-superior position in the glenoid fossa and patient’s TMJ remained asymptomatic after 9 months of postoperative follow-up.

When occlusal alterations are not accompanied by paranasal deficiencies, mobilization of the maxilla via Le Fort I osteotomy should be made with a different design. In this preliminary report, a W-shaped osteotomy that doesn’t change the position of the maxillary bone surrounding the pyriform aperture was presented for the first time. Advantages and indications of this new procedure are discussed.
