Abstract

Bimaxillary orthognathic surgery has been widely performed to achieve optimal functional and aesthetic outcomes in patients
with maxillofacial deformity. Although Le Fort I osteotomy is generally performs before bilateral sagittal split osteotomy (BSSO)
in the surgery, in several situations BSSO should be performed first.
The aim of this study to present the case of a 22 years old female patient with class III malocclusion and facial asymmetry.The
desired movements were planned in 3D virtual planning on the computer with Nemofab software.Any complication was observed
in the postoperative follow-up of the patient.
Conclusion: The maxillofacial deformities are treated with orthodontics and maxillofacial surgery co-operation. Traditional
model surgery is generally used for surgical planning but computer aided virtual planning and printed surgical templates from
3D printers is a good alternative for surgical planning nowadays.
