Patented Dec. 14, 1909.

Application filed February 17, 1909. SerialNo. 478,360.

To all whom it concern:

Be it known that I, EDWIN J. GREENFIELD,

citizen of the United States, residing at.

fication,

Wichita, in the county of Sedgwick and State of Kansas, have invented certain new and useful Improvements in Mountings for Artificial Teeth, of which the following is a.

specification.

The present invention relates in general to dentistry, and more particularly to a novel means for mounting artificial teeth.

The object of the invention is the provision of a peculiarly constructed frame which is adapted to serve as a bearing for the teeth, and which is designed to be inserted into a cavity drilled in the jawbone so as to be held firmly in position when the bone closes in upon the same. 1

For a full understanding of the invention and the merits thereof and also to acquire a knowledge of the detailsof construction and the means for effecting the result, reference tobe had to the following description and is accompanying drawings, in which:

Figure 1 1s a side view of a human face,

' portions of the cheek and jaw bone being removed to show'the manner in which the invention is applied; Fig. 2 is a detail perspective view of the bearing frame and artificial tooth, the said members being separated; Fig. 3 is a side elevation .of the hearing frame and artificial tooth, the base of the tooth being broken away to show the manner 1n which it is a perspective view illustrating another embodiment of the invention; and Fig. 5-is a similar view illustrating still another modihereinafter specifically referred to. orresponding and like parts are referred to in the followin description and indicated in all the views 0 the drawings by the same reference characters.

\ Specifically describing the'present embodiments of the invention and referring now particularly to Figs. 1, 2 and 3, the numeral 1 designates a disk which may be of any desired shape and which constitutes the base or bottom of the hearing frame. Projecting upwardly from this disk are arms 2 which are connected at one or more intermediate points by transverse bracing or ribbing 3.

In the embodiment of the invention illustrated in Figs. 1, 2 and 3 the arms 2 extend substantially parallel to each other. I

4 desi ates a head which may be secured in any is applied to the'frame; Fig. 4-

es'ired way to thelrupper end of the arms 2, and to this head the tooth 5 is'secured by solder or in any other desired way.

In the practical use of the invention, the frame, which is made up of the base, arms, and head, is designed'to be inserted'into a cavity of'the correct size and shape drilled in the jaw bone, the disk 1 resting upon the bottom of the cavity so as to obtain a large bearin surface, while the arms 2 project upwardly with their extremities extending above the jaw bone so as to receive the head 4 and artificial tooth-5. In the course of time, the bone will close in around and through the frame, and the latter will thereby be held securely in position so as to form verse ribbing 3 may be soldered or otherwise connected to the arms 2 and serves to resist the pressure of the bone and to prevent the arms from moving sidewise, and also cooperates with the disk to form a firm bearin Obviously, in those cases where a number of teeth are being removed, two or more of these bearin frames may be installed at suitable positions, and the teeth bridged from one to the other, in the manner well known in the art of dentistry.

In that embodiment of the invention illustrated in Fig. 4, the arms 2*- of the frame diverge in an upward direction from the base 1* and are connected by a plural number of ribbings or cross arms 3, and in this embodiment of the invention the head is mounted to rotate about a central axis, as indicated at 4. Furthermore the said head is provided with a detachable cap piece 6 secured to the head as by the tongue and undercut groove connection 7 shown, so that the tooth may be first soldered to the cap and the cap piece attached readily to the head of the frame, being turned to the desired position, being afterward cemented so that it is held firmly in place. Or, as illustrated in Fi 5, the head there designated 4 is held ri id y on the upper ends of the arms 2* instead of being rotatably mounted thereon, the head 4." being provided with a detachable cap 6". i

' In the practical use of those embodiments .The object in having a movable head is of the invention in which caps are employed, the tooth may be soldered onto the cap and a solid bearing for the tooth. The transthat it is almost impossible in bridge work to insert the tooth frames in such a manner that the bridge will on exactly right, and by having a movabde head it can be. ad: justed. Y

It is to be understood that my improved. frames may be made of gold, silver, platinum, porcelain, or any noncorrosive material.

Having thus described the invention, what is claimed as new is:

1. A bearing frame for an artificial tooth, comprising a disk, a plurality of arms secured to said disk and projecting upwardly therefrom and a head mounted on said arms for supporting a tooth.

2. A device as specified comprising a disk, a plurality of arms carried by said disk, cross braces positioned between said arms and a cap piece for holding a tooth detachably secured upon the outer extremities of said arms.

3. A device as specified comprising a base, 7

arms upwardly extended from sald base,

ribs disposed across said arms at intermediate points thereof, a disk mounted'upon the opposite ends of said arms, a head rotatably disposed on said disk, said head having a groove formed across the upper face of the same, av cap piece carried by a tooth, and a tongue formed on said cap piece for engagement in the groove in said head.

4. A device as specified comprising a base, I

arms upwardly extended from saidbase, a head rigidly carried-upon the upper ends' of said arms, groove formed across the face thereof, a cap engaged on said head and-secured to a toothand a .tongue formed on said cap for interlocking engagement with the groove injsa'id 40 head. In testimony whereof I afix my signature EDWIN J. GREENFIELD.
