3d Orthognathic Surgery in Chile

In 2008 we started our first digital planning in orthognathic surgery. In Chile we were the first team of surgeons with 3D planning. Currently, from our point of view, it is a work standard and must be applied to all our patients without implying extra costs.

The degree of precision and the factors that we can consider can be seen in the following video.

By rotating a maxilla we directly affect the three-dimensional conformation of the mandible. These elements were not easy to quantify with conventional systems. It is currently one of the steps in the design of our surgery.

Remember that the best dental articulator is the patient himself. Reason for which we carried out the assembly of our case in the computer. We have all the spatial parameters coordinated. Dental cad-cam, clinical photographs and bimaxillary cone-beam.

By having our case mounted three-dimensionally, we must segment it. 

First, the segmentation of the skeletal parts, separating the mandible from the rest of the skull and then we carry out the segmentation of the skeleton with the osteotomies that we will perform in surgery.

In the following video I show the two initial stages of segmentation.

At Clínica we have been working with 3D planning in orthognathic surgery since 2008. We are the team that started using these systems in Chile and we have 450 digitally planned cases.

We currently work with dolphin imaging because we consider that it is a simple software to use, it provides a large amount of information, it is easy to interpret and it has a very stable programming code. It has an FDA certification for devices for medical use, which guarantees the handling of patient data and is consistent with HIPPA principles.
