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.

What is claimed is: 
     
         1 .

 a brush handle having a head end and a tail end counter to the head end, the head end having a first surface and a second surface opposite to the first surface, wherein the brush handle is molded by plastic material, the area of the head end is larger than that of the tail end;   a first group of brushes provided on the first surface of the head end and arranged for cleaning a denture surface of the overdenture, the first group of brushes arranged in a curve and corresponding to an outline of the first surface of the head end for matching the surface configuration of the overdenture; and   a second group of brushes provided on the second surface of the head end and arranged for cleaning the tissue surface of the overdenture and the male dental attachments, the second group of brushes extending in an inclined angle from the second surface of the head end away from the brush handle.   
     
     
         2 . The multi-function brush for an overdenture according to  claim 1 , wherein a third group of brushes is provided on the tail end and arranged for cleaning a connective tissue adjacent to the ridge and the female dental attachments, the third group of brushes is softer than the first group of brushes and the second group of brushes. 
     
     
         3 . The multi-function brush for an overdenture according to  claim 2 , wherein the third group of brushes is provided on the tail end on the same side of the brush handle as the first group of brushes. 
     
     
         4 . The multi-function brush for an overdenture according to  claim 2 , wherein the third group of brushes is formed into a conical shape with its brushes converging into a point for easy insertion into the female dental attachments. 
     
     
         5 . The multi-function brush for an overdenture according to  claim 1 , wherein the first group of brushes has three rows of brushes, a central row of brushes is taller than the rest two rows of brushes, the rest two rows of brushes are arranged aside the central row of brushes in a downward and inclined manner. 
     
     
         6 . The multi-function brush for an overdenture according to  claim 1 , wherein a middle section of the brush handle is formed into a grip portion and a surface of the grip portion is selectively provided with a plurality of first slide-proof pads and second slide-proof pads. 
     
     
         7 . The multi-function brush for an overdenture according to  claim 6 , wherein the first slide-proof pads are provided on upper and lower surfaces of the brush handle and have a larger area than the second slide-proof pads provided on side surfaces of the brush handle. 
     
     
         8 . The multi-function brush for an overdenture according to  claim 1 , wherein the inclined angle is defined at a range between 30 degrees to 60 degrees. 
     
     
         9 . The multi-function brush for an overdenture according to  claim 1 , wherein the length of the second group of brushes corresponds to the depth of the trough in the tissue surface of the overdenture.
