ROOT-CANAL FILLING FOR TEETH.

SPECIFICATION forming part of Letters Patent No. 674,419, dated May 21, 1901. A h ati filed March 9, 1901. Serial No. 50,495. (No model.)

T0 (tZZ 1071,0721, it may concern.-

Be it known that 1, CHARLES T. KINSMAN, a citizen of the United States, residing at Williamstown, in the county of Berkshire and State of Massachusetts, have invented certain new and useful Improvements in Root-Canal Filling for Teeth; and I do 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, reference being had to the accompanying drawings, and to the letters of reference marked thereon, which form a part of this specification.

This invention relates to new and useful improvements in root-canal fillings for teeth; and it consists of a central pin of stiff noncorrodible metal or alloy around which is a compound composed of gutta-percha, zinc oxid, and yellow resin, the gutta-percha compound being made to cling tightly to the pin by first roughening the latter by forming small barbs which are coated with the comto harden.

filling the latter, they are too soft to follow narrow or crooked canals. If the fillings are not softened, they do not completely fill the canal, and therefore do not accomplish the purpose for which a root-canal filling is intended.

The object of this invention is to obviate these defects and to produce fillings which cannot double upon themselves or crush together while being inserted in any shape or size of canal, as the metal is made small enough to enter the smallest canals and stiff enough to follow them and will carry sufficient gutta-percha compound to completely fill the canal, regardless of its shape, the excess of the compound being easily pressed back out of the canal and removed.

Owing to the strength of my improved fillings, they may be easily removed, whereas cement or small gutta-percha fillings are difficult to remove.

My invention is clearly illustrated in the accompanying drawings, which, with the letters of reference marked thereon, form a part of this application, and in which Figure 1 is an enlarged perspective View of one of my root-fillings for teeth. Fig. 2 is a central longitudinal section through one of the fillings, said filling also very much enlarged- Fig. 3 is a View of the central rigid metallic portion of the filling.

Reference now being had to the details of the drawings by letter, A designates the central skeleton of the filling, made, preferably, of any suitable non-corrodible metal or alloy, and its circumference is roughened by forming short barbs 13, whereby when the compound of gutta-percha, zinc oxid, and yellow resin is applied thereto and allowed to harden it will cling tightly thereto, and when the fill ing is inserted in the root-canals it will follow the minute and crooked canals, and if for any purpose it is desired to remove the filling it may be easily done, owing to the rigid nature of the filling.

In placing the filling the same should be slightly larger than the size of the canal, and after the filling has been warmed gentlyover a flame it should be dipped in some antiseptic oil to lubricate the filling, after which it should be pressed gently in place.

Having thus described my invention, what I claim to be new, and desire to secure by Letters Patent, is

A root-canal filling for teeth, consisting of a central metallic skeleton coated with a compound of gutta-percha, zinc oxid and yellow resin, as set forth.

In testimony whereof I hereunto affix my signature in presence of two'witnesses.

SANBORN G. TENNEY, MICHAEL S. MONAHAN.
