Modern technologies for orthognatic surgery


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

Materials and methods. From August 2014, 112 bimaxillary surgeries were planned using 3D Dolphin imaging 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 visualisation of planned surgery. Accuracy of fabricated 3D splints are much higher than conventional self or light curing acrylic splints. 3D planning provide the surgeon with a clear picture of planned surgery what makes surgery more predictable and allow to avoid potential complications.
