    Abstract: A method for generating and fabricating a dental device having a body. The body may have a first plurality of tooth receiving cavities shaped to receive teeth of a first side of an arch. The body may also have a second plurality of tooth receiving cavities shaped to receive teeth of a second side of an arch. A palatal portion may extend between the first plurality of tooth receiving cavities and the second plurality of tooth receiving cavities. The palatal portion may be shaped to apply an expansion force to the teeth of the first side of the arch and the teeth of the second side of the arch. The palatal portion may include a plurality of bands that extend between the first plurality of tooth receiving cavities and the second plurality of tooth receiving cavities, each respective band may have a respective different thickness.

    Abstract: Methods for designing a palatal expander. Methods may include forming a digital model of a palatal region and tooth engagement regions. Methods may include forming attachment regions on buccal sides of the tooth engagement regions, the attachment regions shaped and sized to engage with attachments bonded to a patient's teeth. Methods may also include forming at least one breach region corresponding to a thinned region of the palatal expander that extends anteriorly to posteriorly in the palatal region or an occlusal portion of one or both of the tooth engagement regions. The breach region may be configured to breach or bend when a pulling force is applied to one or both of the tooth engagement regions such that the attachment regions are detached from respective attachments.

    Abstract: Releasable and removable palatal expander apparatuses for expanding a patient's palate (“palatal expanders”) and methods of using and making them. These releasable palatal expanders are adapted for ease in removal by the patient or caregiver, and may include a breach region configured to predictably bend or break when a pulling force is applied. The palatal expander apparatuses described herein may include one or more locks for locking the palatal expander onto the patient's teeth. The lock(s) may be unlocked to release the palatal expander from the teeth. A lock may include a control for manually unlocking the lock. Unlocking the locks may allow the palatal expander to automatically disengage from the patient's teeth.
