Resumo: |
Patients with dentofacial deformities type long face have facial height anteroinferior, high occlusal plane, narrow alar base, poor paranasal region, overexposure of the central incisors, increased interlabial distance and gummy smile. Micrognathia usually present with decreased posterior facial high and decreased oropharyngeal airway space and molar Class II. The pattern is long face with a skeletal deformity, aesthetic and functional outcome unfavorable to what drives an orthodontic-surgical treatment. The combined surgery of the jaws is well accepted for the treatment of this deformity in the literature. But the manipulation of the occlusal plane to counterclockwise rotation of the maxillomandibular complex (MMC), thus increasing the aesthetic and functional benefits during this surgery, is seen by some as being an unstable procedure. The aim of this study was to evaluate skeletal stability of counterclockwise rotation of MMC in patients undergoing long face pattern to orthognathic surgery in the long term. This retrospective study consisted of ten patients undergoing this procedure between September 2002 to April 2008. To assess the skeletal stability, 30 cephalometric radiographs preoperative (T1), post-operative recent (T2) and late postoperative (T3) of 10 patients were digited and traced (V.A.C.). Cephalometric points and planes were determined to measure this stability and occlusal and mandibular plane in three times. It was observed that the counterclockwise rotation of the maxillomandibular complex in long face patients undergoing to orthognathic surgery is stable. |
