WITNESSES Ill/VENTOR Gzwam rz ,4 TTUR/VEYS nnin CLAUDE Asronro oonovnn, or NEWBURGH, NEW YORK;

DETACHABLE roorrr.

ToaZZw/wm it may concern: V .Be it known that I, CLAUDEIAAI CONOVER,

a citizenv of .the United States, and a resident of ilewburgh, in the county of Orange and State of New York, have invented a newand useful Detachable Tooth, of which the following is a full, clear, and exact description.

This invention relates to dental work and particularly to an improved removable tooth, and has for an object to provide a construction which will. be mechanically effective for the purpose desired, and at the same time a construction which will present a pleasing appearance. I

Another object of the invention is to provide a removable tooth construction capable of application to a bridge or crown.

A still further object of the invention is to provide a removable tooth which may be applied at any time on the upper or lower 3' aw. V

In the accompanying drawing:

Figure l is a view showing a mouth with a removable tooth applied therein, the same embodying the invention. j

Fig. 2 is a fragmentary sectional view through Fig. 1 on line 2-2. V

F 3 is an enlarged front view of a bridge and supporting plate embodying certain features of the invention.

Fig. 4 is an enlarged rear view of the tooth as adapted to be applied to the plate shown in Fig. 3. I V

Fig. 5 is a sectional view through Fig. 4 on line 55.

Fig. 6 is a sectional view through a single tooth showing an embodiment of the invention applied to a crown.

Referring to the accompanying drawing by numerals, 1 indicates a bridge of any usual or preferred construction, the same being shown as a comparatively narrow strip of metal fastened in a suitable manner to adjacent teeth in such a manner that the removable tooth 2 may be arranged therebetween and present a structure which will appear substantially the same as a natural tooth.

In Figs. 3 to 5 inclusive will be seen details of the tooth, which include a supporting plate 3, soldered or otherwise secured to the bridge 1, said plate being providedwith a snap head or stud 4 and a projection or pin 5. The stud 4 is designed to snap into a socket 6 in the tooth 2, which is made. from porcelain, or any other desired ms. terial. A depression or slot is also formed in the plate 3 and t "the toothf2 for accommodating the pin 5 whereby thetooth cannot rotate. -The socket member 6 is, of course, embedded into the that when it is desired'to apply thfiftooth 2 the same may i jtooth 2 when the same is'beinguf rin d S stud or head 4"whilej the pin 5 moves into the slot 7. The tooth 2 is of exactly the same size as plate 3 or slightly larger so as to be properly supported and backed up by this plate without the plate being seen. i

In Fig. 6 will be seen a slightly form of the invention, inwhich the tooth 2.

is connected to a supporting plate 3, which supporting plate is soldered or otherwise secured to a crown 8 fitted 1n any djeslred or usual manner upon the rear section 9 of the r tooth 10. in this form ofthe invention the tooth 10 must be cut away somewhat to ac oommodate the removable tooth, 2.

modified Specification of Letters Patent. :Pggjjenf d A 1 20 Application filed. January 8, 1920. Serial No. f

ing the tooth 2' of porcelain the gold is not seen, or at least a very small part of the gold is seen, consequently the tooth will present substantially the usual appearance of natural teeth, and when arranged as shown in Fig. 6 will act also as a natural tooth when masticating food.

The structure shown in Figs. 3 to 4 will also act as means for bitingor masticating food, but is not qulte as strong as the structure shown in Fig. 6,. as the bridge is made very narrow in order to'produce a nice appearance. a I

What I claim 1s:

1. A removable tooth comprising a tooth 1 structure, a supporting plate, and means for connecting the tooth structure so that the tooth structure will not move independently of the plate, said means including a snap fastener.

2. A removable tooth of the character described comprising a supporting plate, a pin extending from said plate, a tooth member having an opening for receiving said pin, and a snap fastener spaced from said pin for connecting the tooth member with the plate, said pin acting as means for preventing rotary movement of the tooth member when secured'to the plate,

3. A removable tooth comprising a tooth member provided with a metallic socket and :a pm ad acent said socket, a'base plate for receiving said toothmember, a pin extending from said base plate adapted to fit in sa1d opening, and a resilient stud arranged with the plate for removably connecting the tooth mem her with the base plate.

tending from said 4. A removable itooth comprising a base plate adapted to be'supported by the teeth,

said base plate being formedeof metal, a pin extending from the base plate, a stud exbase plate, tooth adapted to 'fit flatWise against said base plate, said tooth having an opening for receiving said pin, and a metallic socket member embedded in 5. A removable tooth, comprising a removabletooth body, a backing adapted to be connected to. one or more natural teeth,

a porcelain the rear said tooth? for snapping over said stud.

and means presenting a snap fastener for connecting said tooth body with said backing.

6..A'. *removable tooth, comprising a re movable tooth body, a permanently fixed backlng conformingto the shapeein outline of a tooth and to said removable tooth,

means for connect ng said removable tooth with said backing, said means comprising a socket, a resilient stud adapted t said socket for holding the removable tooth body in place, and means for preventing rotary movement of the tooth body around said stud.
