Application filed A ia 13, 1908. semi No. 426,722.

Be it known that I, F RANK D. Case, citi- City, in the county of Jackson. and State of Missouri, have invented certain new and use-- fullmprovements in Artificial Teeth; and 1 do declare the following to be a full, clear, and exact description of the invention, such which it appertains to make and use the ing drawings, and to the letters and figures part of this specification. Y My invention relates to an art1fic1al tooth, and has for its object lDOPI'OVldG a device of both construction and use, and which may be firmly and permanently attached to a plate, bridge or-hke body. In acrmmplishing this object I have provided theimproved details of structure which will presently be fullyilieence being had to the accompanying draw-.

which 1- Figure I is a rear view of a tooth constructed according to my invention. Fig. 11 Fig. III is a side perspective view of the porcelain or like body from which the attaching backing has been-removed. Fig. IV is a similar-view of of the backing with solder added. Referring more in detail to the parts of porcelain or like material and the back of which is shaped in such manner, preferably in the line shown in drawings, to provide for the application of a metal backing member that is better adapted for attachment to a plate or like body than is the porcelain por- Anchored or baked in and projecting from the face of the cut away portion of said porcelain body is a bar 2, the

Fitting against the cut away face of body 1 is a thin plate or backing 3 of metal which can be'readily swaged to the tooth body, and allow penetration of bar 2, the inner surfa e ct which follows the contour of the cut away face. of the porcelain body member, while its outer face is rounded to the curve of a natural tooth byapplying metal preferably composed of solder in order that it may be made to unite an ordinary tooth-plate,bridge, etc, and to the metal plate 3 that is attached to the described tooth body.

-While I have described the plate 3 as comosed of a suitable metal,'I preferably form )oth said plate and the permanent bar 2 of platinum, as such material has been found to e best adapted for the uses noted; the added metal being preferably composed of solder readily shaped to a desired form, and may be quickly, easily and permanently attached to the plate 3, bar 2, and to a tooth plate, bridge, etc. in a mannerfreadilyapparent to those familiar with this class of work. In form: ing the tooth, the bar 2 may be baked with the porcelain or like body member, or a socket may be formed in the tooth body and the bar anchored therein after the body has been baked.

After the bar 2 has been applied to the body 1, the platinum or like plate 3 is placed over the bar and swag'ed or otherwise permanently secured to body 1, a slot 3 being cut in such plate to furnish the passage of the bar therethrough, or the plate being forced there for the reason that such material may be against until pierced by the bar t'ogain the Y 7 lain body member having an inset shoulder at the rear and above its free end, a back plate having a lip adapted to seat on said shoulder and provided with a flange adapted to hook over the rootend of said body, a backing carried by said plate, and a bar anchored in both the body and backing and projected through said plate, substantially as pin-pose set forth.

And for the purpose set 01111.
