A system and method for using a computer to generate dental information of a patient is disclosed. The method involves receiving a virtual digital model of a patient's dentition in a first configuration, the dentition including at least one tooth having a reference volume. The method also involves causing the computer to generate a model volume created as the at least one tooth travels from the first configuration to a second configuration, and causing the computer to subtract the reference volume from the model volume to yield a build-up volume.
Systems and methods are disclosed for repositioning the teeth of a patient by providing a digital model of each tooth of the patient; determining one or more root parameters from the digital model; and digitally moving one or more tooth models and evaluating a treatment outcome based on one or more root movement clinical constraints.
A61C 7/00 - Orthodontics, i.e. obtaining or maintaining the desired position of teeth, e.g. by straightening, evening, regulating, separating, or by correcting malocclusions
A61B 34/10 - Computer-aided planning, simulation or modelling of surgical operations
A61C 19/04 - Measuring instruments specially adapted for dentistry
Systems and methods are disclosed providing a database comprising a compendium of at least one of patient treatment history; orthodontic therapies, orthodontic information and diagnostics; employing a data mining technique for interrogating said database for generating an output data stream, the output data stream correlating a patient malocclusion with an orthodontic treatment; and applying the output data stream to improve a dental appliance or a dental appliance usage.
