Abstract
The aim of this work is to present the advantages of 3D planning and CAD/CAM (Computer Aided Design/Computed Aided Manufacturing) surgical splints in orthognathic surgery. Digitalization of the working environment is an unstoppable reality in our society and, in our specialty it gives us advantages from a logistics, accuracy and diagnostic point of view, as well as in the manufacture process of surgical splints. The conventional surgical splints have an artisanal manufacturing process subjective to systematic errors. CAD/CAM surgical splints are built from computed tomography or cone beam computed tomography, which makes manufacturing process shorter, digitalized and standardized, thus decreasing the errors of the hand made manufacture. The 3D images that we can work with, give us advantages compared to two-dimensional (2D) visualization because there is no loss of information or overlapping anatomical structures. More detailed points of references can be seen in 3D images, which are very difficult to see in two-dimensional images, and are ideal images for the study of frontal plane asymmetry.
