T ATENT MEANS FOR SECURING TOOTH-CROWNS TO ROOTS.
SPECIFICATION forming part of Letters Patent No. 635,773, dated October 31, 1899.
Application filed June 10, 1899.
To all whom it may concern-.-
Be it known that I, HARRY F. HAMILTON, of Boston, county of Suffolk, and State of Massachusetts, have invented an Improvement in Means for Securing Tooth-Crowns to Roots, of which the following description, in
' connection with the accompanying drawings,
is a specification, like letters on the drawings representing like parts.
This invention relates to means" for securing tooth-crowns to roots, and has for its object to improve the construction of the same, to the end that the tooth-crown may be very securely held in place and adapted to with stand a very considerable strain without danger of splitting the root or breaking the fastening.
In accordance with this invention a central pin is secured in a socket or hole in the root, which projects for a suitable distance, and an annular groove is formed in said root concentric to said pin, into Which a ring is fitted which terminates substantially flush with the face or end of the root. A baseplate of suitable size and shape to correspond to the shape of the face or end of the root and of the crown has a central tube secured to and projecting from it, which is adapted to enter a socket or hole in the crown, and said base-plate is placed upon and secured to said ring by fusion or otherwise. The base-plate having the central tube projecting from it is secured to the tooth-crown, and when the parts are assembled the central pin projecting from the root'will enter said tube and will be secured thereto.
Figure 1 shows in vertical section means embodying this invention for securing a tooth' crown to a root; Fig. 2, an enlarged view of one of the parts or members to be referred to Fig. 3, a plan View of the same.
or represents the tooth-crown, andb the root. A pin 0 is secured in a socket or hole formed in the root 1), which projects therefrom for a suitable distance. An annular groove is formed in said root concentric to the pin, into which a ring dis fitted, which terminates substantially flush with the face or end of the root. A base-plate e, of suitable size and Serial No. 720,014. (No model.)
shape, corresponding to the size and shape of the face or end of the root and of the crown, has a central tube a projecting from it, and said base-plate is secured to said ring 61. As a simple way of securing said base-plate to the ring, the ring may be fitted into its annular groove. Then the base-plate having the central tube upon it is placed upon said ring, the tube at such time receiving the central pin a, and by means of a small quantity of any suitable adhesive compound said ring may be caused to adhere to the bottom of the base-plate. The base-plate is then removed with the ring adhering to it and the parts se= cured together by fusion or otherwise.
- The tooth-crown a has asocket or hole which receives the tube 6', projecting from the base plate, and when the parts are assembled the base-plate and tube may be secured to said tooth-crown in any suitable manner.
It will be seen that when the parts are as sembled the pin 0, which projects from the root, will enter the tube which is contained in the socket or hole in the tooth-crown and that said tube, being rigidly secured to the base-plate, is thus supported, and the baseplate, having secured to it a ring which is secured to and practically embedded in the root around the central pin, is also firmly sup ported. The central pin is therefore reinforced to such an extent that the tooth-crown will withstand ordinary strain Without splitting the root or breaking the fastening.
I claim Means for securing tooth-crowns to roots consisting of a central pin 0 secured to the root, a ring 01 fitted into an annular groove in said root concentric to said pin 0, the baseplate 6 to which said ring is secured and the central tube projecting from said base into and secured to the crown which receives said pin 0, substantially as described.
In testimony whereof I have signed my name to this specification in the presence of two subscribingwitnesses.
HARRY F. HAMILTON.
