Abstract
Apparatus for cleaning removable oral appliances, such as tooth repositioning aligners, comprise a base having a tray for holding the appliance in a bath of cleaning solution. A low-frequency driver is provided in the base for reciprocating the tray about a horizontal or vertical axis to wash the cleaning solution over the appliance. Usually, the apparatus will further comprise a cradle which is mounted to reciprocate about a horizontal axis within the base. The cradle defines a receptacle which removably receives the cleaning tray. The cleaning tray is preferably reciprocated at frequency in the range from 1 Hz to 10 Hz, usually in the range from 2 Hz to 5 Hz.
