    摘要: A system and method for evaluating dental treatment utilizes virtual models created from scanned plaster casts. Patient's teeth are directly scanned with a three dimensional scanner or plaster casts of the patient teeth following treatment are scanned for evaluation. A planned configuration based on a plaster cast prior to treatment is created and the desired position and the two models are compared so that the actual position of the teeth may be compared to the desired position after treatment. Superimposition of the virtual models provides accurate and precise measurement of variances between the two virtual models. Difficulties due to superimposing the models, which are of the entire arch and evaluations based on individual teeth are overcome by applying an iterative closest point algorithm to correct the position and provide a truer measurement for evaluation. Differences between a preferred position of a patient's teeth and actual position of a patient's teeth may be assigned a score and the score may be compared to other patients to rank the patient needs.

    摘要: An electronic 3D model of at least a portion of a maxillary arch of a patient is displayed. Inputs indicating a tip 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.

    摘要: A technique for fabricating a surgical splint for use in correcting a dental condition of a patient. The technique involves obtaining a three-dimensional digital model of lower and upper arch dentitions of the patient having the dental condition. Relative positions of the lower and upper arch dentitions are adjusted with respect to each other in the three-dimensional digital model using a computing device. A relative positioning structure is added to the three-dimensional digital model using the computing device. A physical model of the patient's corrected dentition is then generated from the three-dimensional digital model. The physical model includes the relative positioning structure that connects the lower and upper arch dentitions of the physical model at the adjusted relative position. The surgical splint is then formed using the physical model. A non-surgical splint is also described.

    摘要: 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.

    摘要: An electronic three-dimensional (3D) model of a dental arch is displayed. An ideal arch is superimposed on the dental arch. The shape of the ideal arch is adjusted in response to adjustment input from a user. Furthermore, a tooth width is calculated for teeth in the dental arch. A crowding score is calculated based on a comparison of a length of the ideal arch and a tooth width total, the tooth width total based at least in part on a total of the tooth widths for the teeth.
