ARTIFICIAL-TOOTH ATTACHMENT AND METHOD OF MAKING AND UTILIZING THE SAME.
Specification of Letters Patent.
Patented Mar. 4, 1155149.
Application filed October 29, 1918. Serial N 0. 260,103.
.b all 1.0km); it may concern: 7
Be it known that I, JOSEPH I. RICHARDS, a cltlzen of the United States, residing at the city and county of San Francisco and State of California, have invented certain new and useful Improvements in Artificial- Teeth Attachments and Methods of Making and Utilizing the Same, of which the following is a specification.
My invent-ion relates to artificial teeth, particularly those known as plate-toothfacings, their manufacture and their utilization in all classes of crown and bridge work.
The object of "my invention is to provide a simple, durable, inexpensive and practical attachment for artificial-tooth-facings, and uniting them to bridge-work, Richmond crowns, standard crowns, porcelain crowns and all classes of such teeth commonly used and known as crown or bridge-work. In attaining these objects, I eliminateentirely the'use of platinum and I also reduce the quantity of gold necessary to secure results which are both practical and more economicalthan heretofore.
To these ends my invention consists in the novel attachments, and in the method of making and utilizing the same, as I shall now fully describe by reference to the accompanying drawings, in which- Figure 1 is a-posterior elevation of an artificial-tooth-facing.
Fig. 2 is a cross section of the same on the line 22 of Fig. 1, showing the gold-foil lining 3 in the socket or opening 2 of the gauze shell or clip 4: to hold the two backings.
Fig. 5 is a section, enlarged, of the toothfacing, as in Fig. 4, showing the gold solder 9 and the effect of flowing it over the posterior tooth surface.
1 is an artificial-tooth-facing of baked porcelain with the socket or opening 2 on the lingual surface. There may be one or more of these openings of any approved shape, such, for example, as the dove-tail form shown. The opening 2 is lined, as shown in Fig. 2, say, for example, 24 K. gold foil, known as #30 or #60, and which is commonly used as a filling material. The gold lining 3 can be pressed into position or fluXed to the porcelain during the process of manufacture.
Into the gold lined opening 2, as seen in Fig. 3, is pressed a shell or clipel of metallic gauze. The gauze maybe gold, but in practice, a baser metal will'serve as well, and be more economical. This shell or clip is so pressed into the gold lined dove-tail opening as to adapt itself closely and intimately thereto throughout all its wall surface, and a portion or rim of said shell indicated by 5, is left projecting fromthe surface of the facing to serve as a binding ring in the progressive assembling of parts and con struction.
The opening 2 thus lined by the gold 3 and the gauze 4 is now partially filled with a flux wax 6, as a temporary binder.
The artifioial-tooth'facing and its attached parts, as thus far described is the condition of the article as it leaves the manufacturer and is placed on sale for use by practioners.
In the hands of the dentist, the entire lingual surface of the tooth-facing is covered with pure gold foil 7, as shown in Fig. 4, and over this is placed a sheet of metallic gauze 8. The binding ring 5 of the metallic gauze shell or clip 4 is bent down upon the gauze backing sheet 8, to act as a binder,
The completed facing 1, together with other facings similarly constructed and prepared, are now assembled and all are united with gold solder 9 usually employed in such work. The gold solder covers the whole back of each facing and bridges and unites each facing of the assemblage. The effect and. position of the gold solder 9 is shown in Fig. 5. It flows through the interstices of the gauze backing sheet 8 and unites homogeneously with the gold foil backing 7. The heat evaporating the temporary flux wax 6, allows the gold solder to flow into the opening 2 0f the facing, and through the lnterstices of the gauze shell or clip 4. and to unite homogeneously with the gold lining 3. There is thus formed a practically solid with pure or fine gold 3,
gold key holding the facing and uniting all the facings in the assemblage. When baser metals are used for the gauze members, for
' melt and flow the 18 K. gold solder to its union with the gold foil members would without the intervention of the gauze melt and burn said foil. But with the gauze screen present the gold solder unites with the gold foil forming a solid mass and covering the inner surface of the whole assemblage entirely with gold.
The economic features of my invention are now apparent. The use of platinum which is now prohibitive both on account of price and the imperative necessity for its use in other arts, isd'one away with. Platinum pins for artificial tooth-facings have heretofore been required as they alone will stand the heat of baking in themanufacture. But by my construction and method a substitute is found in the gold key as I have described.
The gold and the porcelain tooth are in perfect contact and will allow no fluxes to enter which would tend to crack the porcelain tooth. Inthe finished work each tooth is held securely to the bridge by the gold filled key;
I claim:
1. As a new article of manufacture an artificial-tootl1facing comprising a porcelain member having in its lingual surface a socket; a gold foil lining in said socket; a metallic gauze shell fitted closely to said gold-foil lining; and a body offiux wax to temporarily hold said lining and shell in place.
2. As a new article of manufacture an ar tificial-tooth-facing comprising a porcelain member having in its lingual surface a socket; a gold foil lining in said socket; a metallic gauze shell fitted closely to said fold-foil lining, said gauze-shell having a portion projecting from the inner surface of the porcelain member; and a body of flux wax to temporarily h'cld said lining and shell in place. I p v g Y 3. Crown or bridge work comprising an artificial-tooth-facing having in its lingual surface a socket; a gold foil lining in, said socket; a metallic-gauze-shell fitted closely to said gold foil lining; a gold foil backing for the lingual surface of the facing; a me tallic gauze backing sheet over said gold foil backing; and a body of gold solder covering the gauze-backing, permeating its interstices and united with the gold foil backing, and permeatin the gauze shell in the socket and united with the gold foil lining in said socket.
4. Crown or bridge work comprising an artificial-tooth-facing having in its lingual surface a socket; a gold foil lining in said socket; a metallic-gauze-shell fitted closely to said gold-foil-lining, said shell having a portion projecting from the inner surface of the facingand adapted to be bent down thereupon; a gold-foil backing for the lingual surface of the facing; a metallicgauze backing sheet over said gold-foil backing, both backings being held by the bent down portion of the gauze-shell; and a body of gold solder covering the gauze backing, permeating its interstices and united with the gold foil backing, and permeating the gauze shell in the socket andunited with the gold foil lining in said socket.
5/ The method of manufacturing anartificial-tooth-facing ready for the use'of dental practitioners which consists in first making a porcelain facing with a lingual surface socket; then pressing into said socket a gold-foil lining; then pressing into said socket upon the gold-foil lining a shell of metallic gauze, leaving a portion of said shell projecting from the socket gan'd finally placing a body of flux wax inthe socket to hold the lining and shell in place.
In testimony whereof I have signed my name to this specification in the presence of two subscribing witnesses.
