A multi-function brush for an overdenture includes a brush handle having a head end and a tail end. The head end has a first surface and a second surface opposite to the first surface. The first group of brushes is provided on the first surface of the head end. The second group of brushes is provided on the second surface of the head end. The third group of brushes is provided on the tail end. With these three groups of brushes having different locations, specifications and indications, an overdenture user can clean the tissue surface and the denture surface of the overdenture, the male part of the dental attachments provided on the tissue surface, and the female part of the dental attachments provided on alveolar ridge or roots by this single brush. Thus, the present invention really has convenience and practicability, and the money for buying different toothbrush and denture brush is saved.

An orthodontic distalizing apparatus comprises at least one force generating element positioned intermediate a force dissipating element secured to the hard palate and / or alveolar ridge and a first tooth (e.g., a molar) that is being distalized. The at least one force generating element is positioned to apply a distalizing force on the molar in a direction substantially along a longitudinal axis of the dental arch and at a low level of the basal gingiva. The at least one force generating element may be configured to prevent inadvertent disassembly thereof during installation, adjustment and / or conversion of the apparatus between an active and a passive state. In addition, the at least one force generating element may be configured to be reversibly convertible between an active state and a passive state without requiring removal of the device from the patient's mouth. Moreover, the at least one force generating element may be configured to provide a continuous activation force of substantially constant magnitude during distalization of the molar. The apparatus may also be constructed so that the force dissipating element is connected to at least one anchoring tooth by a slidable coupling that absorbs all reaction forces transmitted substantially along a direction of the longitudinal arch. A second force dissipating element may be positioned intermediate the force dissipating element and a second tooth (e.g., a bicuspid) to facilitate the closing of any gaps that are created following distalization of the molar. A method of converting an orthodontic distalizing apparatus between an active and a passive state is also provided.
