Abstract
An electronic 3D model of at least a portion of a maxillary arch of a patient is displayed. Inputs indicating a peak of a mesiobuccal cusp of a maxillary first molar are received for both the patient'"'"'s right and left sides. In addition, an electronic 3D model of at least a portion of a mandibular arch of a patient is displayed. Inputs indicating relevant points on the mandibular first molar are received for both the patient'"'"'s right and left sides. Side scores are generated for the patient'"'"'s right and left sides based on the indicated points. A final occlusion score for the patient is displayed. The final occlusion score is based on the side score for the right side and the side score for the left side.
