Surgical Control of the Pitch, Roll and Yaw in the Maxillary Arch: A Technical Note

The adequate three-dimensional location of the maxilla is one of the main objectives in orthognathic surgery. We propose an instrument manufactured from a Fox Plane (FP) modified with red light in the shape of a cross and a bubble level, in which we perform an occlusal registration for the trans-surgical control of the three-dimensional position of the maxilla, By adding an occlusal registration to the FP, the occlusal plane is transferred and amplified to an extraoral reference. The red light in the shape of a cross allows us to assess the success of our movements more accurately.
