Abstract

A device for cleaning a dental appliance is disclosed. The device includes a holding container including an upper portion and a lower portion, the holding container adapted to receive at least one dental appliance; an electrolytic cell for generating chlorine dioxide from a chlorine dioxide precursor; and an electrical current supply including a circuit operably connecting the electrical current supply to the electrolytic cell.

First claim

What is claimed is:

1. A method of cleaning a dental appliance outside of an oral cavity, comprising the steps of:
providing a device for cleaning a dental appliance, the device including a holding container including an upper portion and a lower portion, the upper portion adapted to receive at least one dental appliance; and an electrolytic cell for generating chlorine dioxide from a chlorine dioxide precursor; wherein the device further comprises a plurality of cleaning elements disposed on at least one of the upper portion or the lower portion of the holding container, wherein the plurality of cleaning elements comprises at least one conductive bristle;
placing the dental appliance in the upper portion of the holding container;
providing a cleaning composition including a chlorine dioxide precursor;
electrolyzing the cleaning composition thereby forming an aqueous solution including chlorine dioxide; and
maintaining the dental appliance in contact with the chlorine dioxide solution for at least about 30 seconds, wherein the at least one conductive bristle is in direct contact with the dental appliance during cleaning.

2. The method of claim 1 wherein the plurality of cleaning elements is disposed on both the upper portion and the lower portion of the holding container in opposed relation.

3. The method of claim 1 wherein at least one of the upper portion or the lower portion of the holding container is movable to clean the dental appliance disposed there between.

4. The method of claim 3 wherein at least one of the upper portion or the lower portion of the holding container is rotatable.

5. The method of claim 1 wherein the at least one conductive bristle includes an electrically conductive material within a polymer.
