    Abstract: Orthodontic systems for monitoring treatment. The systems can include at least one orthodontic appliance that includes one or more sensors. A processor in communication with the sensor(s) is configured to receive sensor data from the sensor(s), where the sensor data corresponds to a force acting on one or more teeth. The processor is further configured to predict tooth movement based on the sensor data. The predicted tooth movement is determined by predicting how much teeth will move based on a direction and a magnitude of the force. The processor is further configured to compare the predicted tooth movement to an expected tooth movement, where the expected tooth movement is based on a treatment stage of a treatment plan. The processor is further configured to modify the treatment plan if the predicted tooth movement does not match the expected tooth movement based on the treatment stage of the treatment plan.

    Abstract: A system and method for post-processing of polymeric items having a liquid component and a predetermined heat deflection temperature is provided. The system includes a washing station to spray water at elevated temperature and pressure on the items while maintaining the temperature of the item below the heat deflection temperature. Then using a water distillation system to separate the water from the water mixed with the liquid polymer component by evaporating the water using heating coils with surface that is not conducive to adhesion of the liquid polymer component and then condense the water vapor into liquid water. The system may further include a spin station to separate the liquid polymer component by spinning the item. The system may further include one or more processing stations to rinse the item, dry the item, cure the item, remove the item from a tray to which the item may be attached and clean trays after removing the item. A conveyor system may be used to automate the post-processing of the items.

    Abstract: Method and system for managing multiple impressions of a patient's jaw for an orthodontic treatment are provided. The method includes scanning at least a first impression and a second impression of the same jaw for the orthodontic treatment; determining if the first jaw impression and the second jaw impression have distortion in different areas; selecting the first jaw impression or the second jaw impression as a base impression; and replacing distorted tooth data from the base impression with data for the same tooth from a non-base impression. The method also includes scanning at least a first jaw impression for the orthodontic treatment; scanning a bite impression for the orthodontic treatment; matching the scanned first jaw impression with the scanned bite impression; comparing bite information with a tooth occlusal surface; and determining if reconstruction is to be performed on the tooth occlusal surface.
