INSERTABLE AND PREFABRICATED ATTACHMENTS FOR AN ORAL APPLIANCE

Abstract:

A dental appliance includes an interior shape that substantially conforms to a dental arch of a patient, a hollow portion forming a cavity, and an object bonded to the dental appliance and inserted into the cavity. The object provides structural strength to the dental appliance at a location of the hollow portion and does not interfere with a fit of the dental appliance onto the dental arch of the patient.
