Modern technologies for orthognatic surgery

Introduction

Treatment of the congenital and acquired facial deformities are actual problem. Accurate planning of orthognatic surgery cases has been challenge for decades. Emerging new technology makes diagnostics, data recording and vitual surgery possible with creation of surgical templates and splints. New technology opens new possibilities for more accurate surgery planning, ease surgery to achieve better surgical outcome and gives us possibility to shorten operation time.

Materials and methods

From August 2014, 112 bimaxillary surgeries was planned using 3D Dolphin imagining software 11.8 and 11.9 version with preparation of operative splint. Cone beam Icat scan, 3DMD photo, intraoral and 3D shape model scanner are used for treatment planning. 3D printer is used for printing intraoperative splints.

Results

Treatment planning using modern 3D technology opens great visualization of planned surgery. Accuracy of fabricated 3D splints are much higher than conventional self or light curing acrylic splints. 3D planning provide surgeon with clear picture of planned surgery what makes surgery more predictable and allow to avoid potential complications.
