Abstract: Methods and apparatuses for 3D imaging to measure the shape of orthodontic aligners, teeth, and other oral structures simultaneously, in-vivo or in-vitro. These methods and apparatuses may be used to determine contact locations of aligners with teeth and/or teeth with other teeth with very high precision, including determining the size of gaps where they are not in contact. These measurements may be used design, modify or replace an aligner and/or to verify aligner fit. 3D models of the whole aligner and teeth may be generated.

Abstract: Methods and systems for imaging removable dental appliances. Image data taken while a removable dental appliance was worn on a patient's teeth may be used to identify one or more locations of undesirable contact between the removable dental appliance and the patient's teeth and/or one or more attachments on the patient's teeth. The one or more locations of undesirable contact can correlate with undesirable tooth movement compared to expected tooth movement according to a treatment plan. A three-dimensional (3D) model of the removable dental appliance and the patient's teeth may be displayed on a user interface, with the identified one or more locations of undesirable contact highlighted in the 3D model. An alert of the identified one or more locations of undesirable contact may be emitted via the user interface.

Abstract: Methods and apparatuses for 3D imaging (including 3D optical coherence tomography imaging) to measure the shape of orthodontic aligners, teeth, and other oral structures simultaneously, in-vivo or in-vitro. These methods and apparatuses may be used to determine contact locations of aligners with teeth and/or teeth with other teeth with very high precision, including determining the size of gaps where they are not in contact.
