5 Claims. (01. -167) This invention relates to an improved cleaning formed from any suitable material used in appliance in the form of a brush particularly brushes for the mounting and support of bristles, designed for use in maintaining artificiallteeth, such. as molded composition materials, wood, plates, bridges, or other dentures in a cleanly and metal, bone and the like.

The brush is formed to comprise an dimensions, as well as the location and length arcuately shaped body or head 2 which may be of the bristles 4 thereon, results in providing an effective cleaning means for reaching these inaccessible regions with a considerable degree of facility. One end of the brush body is provided with an enlargement 8 having the upper surface 9 thereof formed to be substantially flat and arranged at an acute angle to the horizontal. This upper surface is also provided with perpendicularly disposed bristles 10 which permitthe brush to be reversed in position, from that disclosed in Fig. 3, in order that the bristles 10 may be brought to bear on other surfaces of a given plate which can be cleaned more advantageously with bristles of the kind disclosed at 10 rather than of the type and form as disclosed at 4. Also, one of the ends of the body is provided with a wire loop or bale 11 formed with wire round in cross section. If for any reason cleaning with the bristles of the brush does not result in the desired dislodgement of the foreign matter or film, the same may be removed by scraping with the loop 11. Other types of film may be removed more advantageously by means of a removable stick member 12 received within the socket 13 formed in the end of the brush body opposite to that to which the loop 11 is secured. The stick member maybe formed from a material such as orange wood and provided with a beveled outer edge portion 14, which may be use to scrape the surfaces of a denture to assist, for instance, in film removal.

As a. modification of the above structure, there has been disclosed in Figs. 6 and 7 a brush possessing all of the essential attributes of the brush disclosed in Fig. l but wherein a slightly diiferent cross sectional formation is provided. In this form of-the invention, the body 15 of the brush is provided with a pair of transversely spaced depending ribs 16, instead of the single centrally disposed rib 3 set forth in Fig. 3. By the use of a plurality of ribs 16, an arcuate groove 17 is formed between said ribs and the body 15 which, as shown in Fig. 7, is of such width as to receive within it the gingival flange 18 of the plate 19, and bristles 20 project inwardly and perpendicularly from the inner surfaces of the ribs '16 and the lower surface of the body 15 in order that both the inner and outer surfaces of the flange 18 may be simultaneously cleaned by the operation of the brush.

In view of the foregoing, it will be seen that .the present invention provides a cleaning appliance which has been particularly constructed and designed for facilitating thorough and ethcient cleaning of artificial tooth dentures. The appliance involves in a single instrumentality all of the features necessary to reach and clean the surfaces, both accessible and relatively inaccessible, of a dental plate and avoids specifically the use of a multiplicity of separate instrumentalities heretofore largely used in operations of this kind such, for example, as the employment of separate sticks, wire members and various types of brushes. While the invention has been described in considerable detail, it will be understood that it is subject to variation or modification without departing from the scope of the appended claims.

What is claimed is:

1. A cleaning appliance for artificial teeth comprising an arcuate body shaped to conform substantially to the marginal curvature of a dental plate, bristles projecting from the lower surfaces of said body, and a manipulating member integrally formed with said body arranged above and possessing substantially the curvature thereof, said manipulating member being of such height that it can only be held by the finger tips of the operator.

2. A dental brush comprising a body of arcuate formation shaped to conform substantially to the curvature ofthe marginal portion of a dental plate, a flange of arcuate form depending from the under surface of said body, brush bristles embedded in said flange and extending outwardly therefrom, and an arcuately shaped manipulating handle formed with the upper portion of said body and arranged in vertical alignment with said flange, said manipulating handle together with said body and flange produces a cross shaped transverse sectional formation of the brush. I

3. A dental brush comprising an arcuate-body having a cross-shaped transverse sectional forination with the upper end of the cross forming the handle for the brush, and brush bristles carried by the under surface of the cross arms and with bristles extending outwardly from the surfaces of the lower member of the cross.

4. A dental brush comprising an arcuate body shaped to conform substantially to the curvature of the gingival regions of a dental plate, flanges formed with said body'having substantially the curvature of the latter and forming with said body vertical and horizontal faces, brush bristles i CHARLES SWOPE. -LOU DUNLAP LAIRD.
