Abstract: Systems and methods for orthognathic surgical planning are described herein. An example computer-implemented method can include generating a composite three-dimensional (3D) model of a subject's skull, defining a primal reference frame for the composite 3D model, performing a cephalometric analysis on the composite 3D model to quantify at least one geometric property of the subject's skull, performing a virtual osteotomy to separate the composite 3D model into a plurality of segments, performing a surgical simulation using the osteotomized segments, and designing a surgical splint or template for the subject.

Abstract: Systems and methods for orthognathic surgical planning are described herein. An example computer-implemented method can include generating a composite three-dimensional (3D) model of a subject's skull, defining a global reference frame for the composite 3D model, performing a cephalometric analysis on the composite 3D model to quantify at least one geometric property of the subject's skull, performing a virtual osteotomy to separate the composite 3D model into a plurality of segments, performing a surgical simulation using the osteotomized segments, and designing a surgical splint or template for the subject.

Abstract: Methods and systems for establishing dental occlusion are described herein. These systems and methods can be used for 1-, 2-, or 3-piece maxillary orthognathic surgeries. An example computer-implemented method includes receiving a maxillary dental model and a mandibular dental model, identifying a plurality of dental landmarks in each of the maxillary and mandibular dental models, and extracting a plurality of points-of-interest from each of the maxillary and mandibular dental models. The dental landmarks include a plurality of maxillary dental landmarks and a plurality of mandibular dental landmarks. The method further includes aligning the maxillary and mandibular points-of-interest, and fine tuning the alignment of the maxillary and mandibular dental models to achieve maximum contact with a collision constraint.

Abstract: Systems and methods for estimating a patient-specific reference bone shape model for a patient with craniomaxillofacial (CMF) defects are described herein. An example method includes receiving a twodimensional (“2D”) pre-trauma image of a subject, and generating a three-dimensional (“3D”) facial surface model for the subject from the 2D pre-trauma image. The method also includes providing a correlation model between 3D facial and bone surfaces, and estimating a reference bone model for the subject using the 3D facial surface model and the correlation model.

Abstract: The present disclosure is directed to a customizable distractor for oral and maxillofacial surgery and a system and method for designing and making the same. The distractor includes a steering apparatus that is movable along the helical-shaped distraction path to create gap between the first and second bone segments, an anchoring member for coupling the steering apparatus a first and second bone segment, and a distraction drive mechanism is used to drive movement of the steering apparatus along the distraction path.

Abstract: A method of forming a surgical splint to receive a patient's dentition and thereby align the upper jaw and the lower jaw during surgery includes generating a CT computer model of bone structure, generating a digital dental computer model of the patient's dentition, and then combining the CT computer model and the digital dental computer model to form a composite computer model. The composite computer model may be displayed, and at least one of the upper jaw and lower jaw repositioned relative to the patient's skull and the composite computer model to form a planned position computer model. Using this desired position computer model, a computer model surgical splint of the patient's dentition may be formed, which is then input into a fabrication machine to form a surgical splint. The method also includes forming and displaying the composite computer model. A workstation includes a CT machine, a digital scanner, a computer, an input command mechanism, a display, and a fabricating machine.
