NITED STATES PATENT. EEICE.
WILLIAM III. sEEGER, on LOUISVILLE, KENTUCKY.
-ARTIFICIAL TooTH-oRowN.
SPECIFICATION forming part of Letters Patent No. 544,389, dated August 13, 1895.
Application filed December 13, 1894. Serial No. 5311710. (No model.)
To all whom, t may concern.'
Be it known that I, WILLIAM M. SEEGER, a citizen of the United States, residing at Louisville, in the county of Jefferson and State of Kentucky, have invented certain new and useful Improvements in Artificial Tooth-Crowns; and I do hereby 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.
My invention relates to artificial toothcrowns, preferably of porcelain, and designed to be applied to natIiral-tooth roots remaining in the mouth, but may be used in other artiiicial dentures. One or more pins are attached to the base of my improved crown by a ball-and-socket joint. There may be as many pins as there are nerve-canals in the natural-tooth' root. By reason of the pin being hinged when the artificial tooth-crown is placed on the natural-tooth root the pin will follow the nerve-canal in the root in any direction without requiring to bebent and thus subjected to liability to being weakened or fractured.
In the accompanying drawings, Figure lis a vertical section through my improved crown and the pin, showing the joint placed above the base of the crown; and Fig. 2 is a like view of the same, showing the joint embedded in the base of the crown, which form may be used when necessary. Fig. 3 shows the ball in the lower and the socket in the upper portion of the pin..
In the accompanying drawings, A is the ar tiiicial tooth-crown, B is its base, C is the pin, and D the ball-and-socket joint, which in Fig. l is secured to the tooth-crown by having the lug E embedded in the material of which the crown is composed.
In the drawings the ball of the joint is formed upon the pin; but ifso desired the socket of the joint may be formed upon the pin and the ball secured to the toothcrown by a lug, as shown in Fig. 3.
In use the natural-tooth root is so shaped that the artificial tooth-crown will be in a proper position in the mouth when its base is placed against such natural-tooth root. The pin is secured in the natural-tooth root by meansA of cement.
I do not in this application claim a hinged pin in connection with an artificial toothcrown, as the same forms the subject-matter of an application led by me November 1l, 1893, Serial No. 490,707; but
The combination with an artificial tooth crown, of a pin secured to its base by a universal joint and adapted to be secured in the natural tooth root.
In testimony whereof I affix my signature in presence of two witnesses.
WILLIAM M. SEEGER.
Witnesses:
A. J. BRANDEIs, JAMES W. BEATTIE.
