1. A computer-implemented method for analyzing occlusion, the computer-implemented method comprising:

  • for both a right side of a patient and a left side of the patient;

    displaying a three-dimensional (3D) model of at least a portion of a maxillary arch of the patient;

    receiving input indicating a first point on the electronic 3D model of the portion of the maxillary arch, the first point corresponding to a peak of a mesiobuccal cusp of a maxillary first molar;

    displaying an electronic 3D model of at least a portion of a mandibular arch of the patient;

    receiving input indicating a second point on the electronic 3D model of the portion of the mandibular arch, the second point corresponding to a peak of a mesiobuccal cusp of a mandibular first molar;

    receiving input indicating a third point on the electronic 3D model of the portion of the mandibular arch, the third point corresponding to a peak of a distobuccal cusp of the mandibular first molar;

    receiving input indicating a fourth point on the electronic 3D model of the portion of the mandibular arch, the fourth point corresponding to a contact point between the mandibular first molar and a mandibular second premolar;

    receiving input indicating a fifth point on the electronic 3D model of the portion of the mandibular arch, the fifth point corresponding to a contact point between the mandibular first molar and a mandibular second molar;

    generating, by a computing device, a central axis, the central axis being a line on a plane, the plane being parallel to an occlusal plane of the patient;

    identifying a location of a scoring intersection, the scoring intersection being a point where the central axis and a scoring line intersect, the scoring line being a line on the plane, the scoring line being perpendicular to the central axis and passing through a point projected onto the plane by the first point; and

    generating a side score based on the location of the scoring intersection relative to measurement intersections, the measurement intersections being pointswhere the central axis and measurement lines intersect, the measurement lines including lines on the plane perpendicular to the central axis; and

    displaying a final occlusion score for the patient, the final occlusion score based on the side score for the right side and the side score for the left side.
