3D virtual planning and digital workflow have become standard in orthognathic surgery. These new technologies have created new options for teaching and learning by following all surgical treatment steps in advance.
This includes designing individual hardware which is of imminent importance especially in maxillary advancement and downwards movements when one follows the maxilla first concept and is independent of any condyle position.
The only consisted weakness in all planing softwares still has to be seen in soft tissue prediction and is still goal for the future.
Especially in Surgery First or Surgery Early cases, the digital definition of the desired occlusion and alignment of the dental arches together with the orthodontist, represent an important step in the surgical treatment plan. The final decision whether maxillary segmentations are needed depends on this simulation. This virtual planning is also used as information for postoperative orthodontic finish with robotically designed arch wires.
All these arguments will be underlined and explained by showing clinical cases.
