Multi-function brush for overdenture

Abstract

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. A first group of brushes is provided on the first surface of the head end. A second group of brushes is provided on the second surface of the head end. The first group of brushes is arranged in a curve and corresponding to an outline of the first surface for matching the surface configuration of the overdenture. The second group of brushes is extending in an inclined angle from the second surface away from the brush handle. Under this arrangement, an overdenture user can clean the tissue surface and the denture surface of the overdenture and the male part of the dental attachments provided on the tissue surface by this single brush.

AI Technical Summary

Benefits of technology

The present invention is a multi-function brush for cleaning an overdenture and its attachments. The brush has three groups of brushes with different locations and indications. The user can clean the denture surface, the tissue surface of the overdenture, the male parts of the dental attachments, and the female parts of dental attachments on roots by using a single brush. This invention provides convenience and practicability and saves money for the user.

Problems solved by technology

The construction and maintenance of the removable overdenture are more complicated than those of the removable complete denture.

First, it has to verify whether the remaining tooth root of the patient is still usable.

Especially, unlike the tissue surface and the denture surface of the overdenture that are both made by resin, the connective tissue adjacent to natural roots or artificial roots is still of vital tissue and thus cannot be cleaned by the rigid brushes for cleaning the acrylic resin.

Further, the user cannot see the positions of the natural roots or artificial roots clearly, and some roots are even located near molar teeth in the posterior areas of the oral cavity.

As a result, the user often needs to buy two different brushes.

One is used to clean the overdenture outside the mouth, and the other is used to clean the connective tissue and natural or artificial roots inside the mouth, which causes the inconvenience in use and increase in money.
