In the last years the computed tomography (CT) had been used in maxillofacial surgery for dento-skeletal deformities diagnosis and treatment planning. It is important to have precise information, which is then reproducible in the operating room. CT provides accurate information in order to obtain optimum aesthetic and occlusal results. The move from 2D to 3D imaging provides surgeons and patients information about the surgery that cannot be obtained from lateral tele-radiography alone. It is also possible to interact with these 3D images simulating the surgery that will take place and producing postoperative outcome in soft and hard tissues.

The aim of the study is to present a 3D planning in orthognathic surgery protocol applied to 10 patients. Different dento-skeletal diagnosis and treatment planning using the Simplant OMS software will be presented. The advantages/disadvantages of this protocol and the possibilities to be applied in our country will be exposed.

This is a prospective study of 10 patients who underwent orthognathic surgery using CT scan 3D planning. All patients had pre-surgical CT scans. The preoperative variables recorded were; photographic records, articulated casts, Delaire cephalometric analysis obtained from lateral x-rays and 3D cephalometric analysis using Simplant OMS software. The surgery simulation was done with the Simplant “surgi planning” application.

The use of 3D planning and computer assisted surgical simulation provides the surgeon and the patient the best possible scenario for preoperative treatment planning.
