ARTIFICIAL TOOTH,
' Specification of Letters Patent.
Patented Feb. 16, 1915.
To all wiwfl't it may, concern;
Be it known that I, 'lnonrss G. lcManon, citizen of tho ljnitod States, residing at? Winnetlta, in the county of Cook and State of Illin is, have invented certain new and useful Improvements in Artificial Teeth, of which the following is specification.
This invention has reference to improvements in artificial teeth and relates more particularly to porcelain long-pin-teet-h, known as faoings, with metal pins baked therein.
In the drawings: Figure l is an enlarged sectional View of a tooth showing my improvedpin: Fig. 2 is a trans so sectional view of the tooth showing position of pins; ig. 3 is an enlarged detail view of a pin,
and Figs. 4 to 8 both inclusive, show e'nlarged modifications of the p 1.
Like characters of retiersnce denote corre sponding parts throughout the The object of the present invention is to provide a pin for a tooth which will present better longitudinal resistance stress of mastication on which. the acking will slide more easily into positio and by the use of which the cost of manufacture is con siderably reducod.
1 designates a suitable tooth and tho pins, Those pins 51 are or fiat metal or 11b;- bon shape and made preferably of Knetai thirtyfour or thirtwsix That portion of tho pins w! o in the teeth have roughened, note 0.. to facilitate in hold the some firmly therein. Tho protruciln ortious of tho pins approxirnat -he:1d sl or pointed, as at 'n y rounded corners, as at Ends and rounded one or attachium t I.v ficial porcelain artificial baked in g arc longz cr The pin 6 in Fig. 4: has its protruding edges roughened or saw edged, as at 7, serviceable for rubber attachment.
In Fig. the pin 8 has a wedge shaped portion 9 which is baked in the tooth, thus doing away with the roughened or saw tooth edges.
In Fig. 6, the pin 10 has the portion 11 which is baked in the tooth perforated, as at 152 The porcelain will enter these perforations to retain the pin, thus doing away with the roughened edges or wedge shape in the tooth,
In Fig. 7 the pin 13 hasits entire body porforatod, as at 14, while the pin '15 shown in Fig, 8 has reversal wedge shaped portions as at 16 and 17. i
Figs; 3, 5 and 6 are suitable for crown or bridge work and Figs. 1, 7 and 8 are suitable for rubber work.
Although the pins may be modified in construction to provide for securing same in the teeth and to adapt same for crown or bridge work or rubber work, they eaohand all have the same efiiciency so far as resisting longitudinal strain during mastication.
'With the use of round metal pins in facings of the character herein, in a great many when the pins are bent over, after the backiig been. placed in position, they being still and firm, will fractureor crack the porcelain. By using flat ribbon-like pins of very thin gage, this danger is entirely obviated for the reason, that thc pins are very pliable and may be bent laterally with out danger of fracturing or cracking the porcelain. and yet there is sufficient body to insure a firm and permanent connection be- 1 facing and backing.
7 at I claim n, a porcelain facing, pins attaching the facing a suitable i381 raid pins being bakod facing with iltji'lS protruding from is l'erior surface thereof, each pin benot or ribbozrlike in crosssection, with 5 "*oatest width of the pins extending udinally of the facing; the edges of. portion of the pins baked in. the facing r notched to insure the pins being held in the porcelain, and the protruding the being pointed with ornors, adapt the easy j over said pins. new article of manufacture, an
o )ted to l;
anchor for an artificial tooth facing, comprisin metallic plate having anchoring means on the part of said plate to be inclosed in the facing, and penetrating means on the other end of said plate. I
'3. As anew article of manufacture, an anchor for an artificial tooth, comprising a very thin rigid metallic plate having a substantially rectangular body portion, one end of said body portion being pointed to pro- ,a very thin lei-laterally symmetrical vide a penetrating member, the other end of said body portion comprising an anchoring THOMAS e. QMQMAHON.
