Maxilla Pseudoarthrosis Ten Years After Orthognathic Surgery: Case Report

ABSTRACT: Many orthodontic treatments alone cannot reestablish an ideal occlusion, requiring correction through orthognathic surgery. An adequate surgical planning, execution and case follow-up can provide surgical stability between the maxilla and the mandible. Soft tissue conservation and proper c...

An adequate surgical planning, execution and case follow-up can provide surgical stability between the maxilla and the mandible. Soft tissue conservation and proper correction during a healing phase are important to achieving this goal. Patient C.L.B.S, 38 years old, female, presented with Angle Class I occlusion, facial profile class II, maxilla with mobility, chin surgically advanced and anterior open bite. She was submitted to orthognathic surgery 10 years ago. In the panoramic radiography the absence of bone formation in the maxilla was observed, causing an open bite. For the surgery conventional radiographs were used, as well as the dental cast in articulator for model surgery and preparation of surgical guide. With the surgery an improvement in the patient's aesthetics profile and an ideal occlusion, static and functional were expected. The treatment was orthodontic-surgical, with correction of the dento-facial deformity with counter-clockwise rotation of the maxilla, lowering repositioning in 3 mm of its posterior portion through Le Fort I osteotomy, advancement of the 4 mm mandible with bilateral sagittal osteotomy, and genioplasty for posterior repositioning with a Z-osteotomy, to improve mentual harmony. There was an improvement in the profile and aesthetics of the patient, which developed an Angle Class I profile, a decrease in the mentual projection, and an aesthetic and functional improvement. The orthognathic surgery allowed the advancement of the mandible, the repositioning of the maxilla and the mentual posterior repositioning, obtaining the correction of the Angle class II profile and the anterior open bite, resulting in an important improvement of facial profile and esthetics, presence of skeletal stability, restoration of function, self-esteem and quality of life.info:eu-repo/semantics/openAccessUniversidad de La Frontera.
