Abstract: Systems and methods for forming eruption compensation (EC) features in dental appliances for accommodating erupting teeth. An EC feature may be oversized compared to a predicted geometry of an erupting tooth, thereby allowing natural eruption of the tooth when a subject wears the dental appliance. The size, shape, location and/or orientation of the EC feature may be determined based on a virtual EC region in a virtual dental model of the subject's teeth. Dimensions of the virtual EC region may be calculated using a scaling process applied to the predicted geometry of the erupting tooth. In some cases an asymmetric scaling may be used to provide a prescribed larger lingual or buccal side of the EC region to accommodate an ectopically erupting tooth.

Abstract: Methods and apparatuses are disclosed for electronic devices associated with monitoring a patient's use of an intraoral dental appliance. The monitoring electronics may communicate with near-field communication (NFC) signals. An NFC booster is disclosed to improve NFC data transfer between the electronic devices that monitor patient usage and communication devices. NFC boosters may be included within dental appliance cases and/or mobile phone cases. Also described are method and apparatuses for mounting the monitoring electronics onto the dental appliance. Also described are compact sensors, e.g., capacitive sensors, that may be included as part of a monitoring electronics unit.
