Virtual Digital Articulation Versus Hand-articulation Accuracy for Occlusal Registration in Orthognathic Surgery

Conventionally, orthognathic occlusal planning is performed by physically articulating the study models until a well interdigitated occlusion is achieved. this is undertaken in conjunction with the analysis of the face and jaw bones for surgical planning. Computer-assisted planning now allows digital planning of orthognathic surgery, including assessment of the quality of the final occlusion and printing of the guiding occlusal wafers. This can be achieved through the replacement of the defective images of the dentition produced by the cone beam computed tomography (CBCT) scan with accurate digital images of the study models, captured using CBCT or laser scanning
