Description
W, B. FLOYD ARTIFICIAL TOOTH Filed Aug. 5, 1919 Patented July 29, 1924.,
WILLIAM B. FLOYD, OF DENVER, COLORADO.
ARTIFICIAL TOOTH.
Application filed August 5, 1919.
,7 all whom it may concern:
Be it known that I, IVILLIAM B. FLoYD, a citizen of the United States, residing in the city and county of Denver, in the State of Colorado, have invented certain new and useful Improvements in Artificial Teeth, of which the following is aspecification.
My invention relates to an improvement in artificial teeth, and I do hereby declare the following to be a full,'clear, and exact description of the invention, such aswill enable others skilled in the art to which it pertains to make and use it, reference being had to the accompanying drawings which form part ofthis specification.
Teeth having a porcelain cusp have heretofore been made, but on account of their shape do not afford sanitary cleansing space, and the method of attaching the por celain to the gold is entirely different.
The object is to design a facing principally for bridgework, but one which may be used in the construction of metal plates and in crown work. j
' This invention consists of a porcelain facing so constructed as to afford afull porcelain cusp, obviating the showing of gold in the mouth, and still affording a sanitary surface for cleansing. I
In the accompanying drawings Fig. 1 is a side view in Vertical section of the anterior tooth;
Figure 2 is a similar View of the posterior tooth;
Figure 3 isa back View showing palatal and lingual angles of the anterior tooth;
Figure 4 is a similar View showing angles of posterior tooth;
Figure 5 shows cleansing surface when in proximity to the gum.
Fig. 6 is a View showing backs of two teeth. 7
A, represents thepi'ns, preferably of platinum, there being two in each tooth, which are baked into the porcelain teeth 1 at an angle (approximately as shown in Figs. 1
Serial No. 315,518.
and 2) which imbeds them into the thickest portion of the tooth affording unusual strength.
In figure 5, I have illustrated the relation of the tooth to the gum, the gum being rep I resented by the numeral 2, and B indicating gold used in backing up teeth in order to solder them together at back.
It will be observed with the sides toward the base,.there is greater space in the back of the porcelain cusp for a larger supply of. metal backing at the juncture between teeth (as shown at 4 in F 3, 4L and 6) this being due to the angle of the porcelain, and affording added strength in metal at line of union of teeth;
The fundamental features therefore reside First, in the full porcelain cusp in which the back of gold is concealed;
Second, the improved method of attaching porcelain to the gold, affording superior strength;
Third, the arrangement whereby the cleansing when in proximity to the gum affords improved sanitary conditions;
Fourth, the tooth as constructed, upon a whole, is stronger, better formed, more natural-looking, more sanitary, and less objectionable as to showing gold than teeth heretofore used for like purposes.
I claim:
Artificial teeth including two or more cusps hollowed out on the back, this hollowed out portion enlarged and deepened at the edges of each cusp, and a metal back= ing facing this entire hollowed portion, whereby the latter is of greater width at the edges of the teeth and at the point of juncture of the metal between teeth, thereby affording a maximum of strength at the point Where the greatest strain upon the teeth comes. a
In testimony whereof I afiiX my signature.
WILLIAM B. FLOYD.
