SPECIFICATION forming part of Letters Fatent No. 605,403, dated June '7, 1898. Application filed November 9, 1897. Serial No. 657,956. (No model.)
To all whom it may concern: Y
Be it known that'we, CHARLES A. DAVIS, residing at Pasadena, and EMORY L.- T0wN- SEND, residing at Los Angeles, in'the county of Los A'ngeles and State of California, citizens of the United States, have invented cer- I tain new and useful Improvements in Crowns and Clamps for Bridgework; and we do declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same, reference being had to the accompanying drawings, and to the letters of reference marked thereon, which form a part of this specification.
This invention relates to new and useful improvements in dentistry, and especially to the construction of artificial crowns for teeth and in the manner of securing same to a dental bridge which is provided with a seriesof cups or sockets, each of which sockets has a to receive the crown, which, after being adjusted in place, may be securely cemented to the socket.
An important advantage of the present system is that it admits of being repaired without removal from the mouth, and in case a tooth is broken off or a change for any purpose is desired it is not necessary to remove the bridge, for the reason that there is no solder used in fastening the teeth in position; but each tooth is cemented in a gold cup or socket, which holds same as securely and per-' manently fastened as though soldered to a gold backing. I In our system of bridgework from a sanitary point of view there is not the slightest possibility for food or secretions of the mouth to permeate or in any way get between or under any layer of gold, as the cement secures every point surrounding the crown and the gold solder effectually joins the several gold cups totheir attachments and fills up the interstices between the teeth, thus not leaving any crevice or corner where secretions can lodge. By reason of our novel manner of fastening the crowns to the bridge there is no danger of the crownsbecoming discolored, fractured, or broken by heat, which are commore fully hereinafter described, shown in the accompanying drawings, and then specifically defined in the appended claims.
Our invention is clearly illustrated in the accompanying drawings, which, with the let ters of reference marked thereon, form a part of-this specification, and in which-- Figure 1 is a perspective View of a bridge with the crowns shown as fastened to the cups or sockets of the bridge. Fig. 2 is a like view taken from the front side, showing two of the teeth removed in order to better illustrate the construction of the sockets and pins for holding the crowns. Figs. .and at are sectional (views through the bridge upon lines 3 3 and ateof Fig. 1, a tooth in each instance being shown as held in place in the socket or cup and the manner of securing the tooth on the pin being illustrated.
Reference now being had to the details of the drawings by letter, A designates the bridge, which at one of its ends is provided with an anchoring-pin B, which is to be secured to a tooth in the usual manner, and at the opposite end of the bridge is the cap 0, which is to be fitted over a secure anchorage. Forthe reception of each tooth a socket E is formed inthe bridge,whichis made by stamping the same froln gold, and in the center of each socket or cup E is a pin F, which is corrugated along its shank portion and has a shoulder F, which is designed to fit within the recessed portion of the crown G. The under surface of the crown-tooth is preferably made upon a curve to conform to the bottom of the cup or socket andhas centrally formed therein a recess for the reception of the corrugated pin, with its enlarged or shouldered portion, the said recess being of sufficient size thus leaving the lingual side of the bridge quite open, so as to permit of its being readily cleansed by the use of a brush.
The crown may be curved, grooved, or otherwise shaped, whereby the cement will serve to more securely hold the same in the socket, it being the object of the present invention to simplify the making and repairing of dental bridges, rendering it possible to readily remove the crown, and not subjecting it to heat, which would tend to discolor or break the crown.
Having thus described our invention, what We claim to be new, and desire to secure by Letters Patent, is
1. In dental bridgework, the bridge, the integrally-formed sockets thereon, a corrugated pin integral with the base of each socket, and a double-ended pin extending through the base of one of the said sockets, combined with the crowns fitted in said sockets and means for holding same on the socket-pins, as set forth.
2. In dental bridgework, the bridge made up of a series of sockets, integral corrugated and shouldered pins, one in each socket, one of the sockets being double with a common base and a double ended pin extending through the said base thereof, combined with crowns secured as shown and described.
In testimony whereof we affix our signatures in presence of Witnesses.
