Title: PALATAL EXPANDERS AND METHODS OF EXPANDING A PALATE
Abstract:
Palatal expander apparatuses for expanding a patient's palate ("palatal expanders") and methods of using and making them. These palatal expanders may be configured to have a variable surface smoothness on one side (e.g., the lingual-facing surface) compared to the opposite side (e.g., the palatal- facing surface). These palatal expanders may be configured to have a varying thickness in the palatal region. These palatal expanders may be adapted for ease in removal by the patient or caregiver (e.g., including a hinged region and/or detachment region, and/or including a thinner buccal side then occlusal side, etc.).
