  • Publication number: 20230024583
    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.

  • Publication number: 20210267718
    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.
