I, Carl Otto Juterbock, of 46 Lennard Road, Penge, in the County of Surrey, Goldsmith, do hereby declare the nature of this invention (a communica¬ tion to me from Paul Sorge. of Junkerstrasse, Fiirstenwalde, in the Empire of Germany, Dentist) to be as follows : — 5 The invention relates to that class of artificial teeth in which crowns are provided with pins or pivots and are connected to natural roots by means of cement. Hitherto these pins or pivots have been made solid and have been of com¬ paratively small cross section. According to this invention the pin or pivot is made hollow and is attached to 10 a plate of metal, which forms a stop or base plate and rests against the exterior portion of the root of the tooth. The tooth is attached to the base plate in any well known manner. In some cases I attach an [__ shaped piece of metal to the hollow pin, in which case one arm forms the base plate and the tooth or crown is attached to the other 15 arm. These hollow pins or pivots are formed with holes at each end, and a hole is also formed through the base plate. A number of other holes are drilled through the walls of the pin and some notches are also cut therein. The root of the tooth is drilled out and filled with plastic cement. The pin or 20 pivot, to which is attached the artificial tooth or crown, is then pressed softly into position, the cement passing through the boles to the interior and the excess escaping through the hole in the base plate. The pin or pivot, being much larger than hitherto, forces the cement well against the interior of the root, but at the same time it avoids excessive pressure therein as the superfluous cement can readily 25 escape. it will be well understood that the cement passing through the holes and filling the interior of the pin will attach this latter to the walls of the ro >t more firmly than the solid pins hitherto in use. Another advantage to be derived from the use of this invention is that when 30 an abscess forms at the root of a tooth fitted with an artificial crown, a hole may be drilled through the cement to the point of the root and a suitable remedy may thus be applied without removing the crown. The above description relates to artificial incisors and cuspids but it is evident that similar hollow pins may be applied to bicuspids and molars. In this case a 35 hole or holes would be drilled through the crown to allow the superfluous cement to escape. Dated this 19th day of September 1895.
