Improvements in or relating to Fastenings for Artificial Teeth.
I, HUGO KALBE of 106 Kurfürstenstrasse Charlottenburg, Berlin W. in the
Empire of Germany, Dentist do hereby declare the nature of this invention and
in. what manner the same is to be performed, to be particularly described and
ascertained in and by the following statement :-
The method of attaching or fastening artificial teeth in, or on to the guttapercha
or similar plate hitherto employed, consists in the teeth having two or more
platinum pins, which, when their projecting ends have been bent round or flattened,
are pressed into the guttapercha or other plate. It frequently happens however
with this defective mode of fastening that the artificial teeth break off or fall out
and the wearer of them is liable to swallow the broken part which, with the sharply
curved platinum pins and sharp edged pieces of the plate attached thereto, cause
serious inconvenience, if not danger to life.
This invention has for its object to remove this danger as well as the
inconvenience and extra expense by the breaking off or falling out of a tooth. It
is possible with this process to fasten artificial-teeth- to gutta percha, gold or the
like plates in such a way that the teeth can only break off in case of the entire
destruction of the whole plate.
In Figures 1, 2, 3, 5, 6 and 7 of the accompanying drawing, separate teeth are
shown in section and in elevation.
Figures 4, 8, 9, 10 and 11 show the method of attaching the separate teeth in
the plate and also the manner of connecting if desired the separate teeth with one
another.
Each artificial tooth Z, see Figure 1, has a double T shaped loop or hook /
which is fastened in the usual manner in the tooth. This double T shaped piece
may also be of any suitable form, for instance divided as shown in Figure 2.
Another way of making the loop is shown in Figure 3 in which a bar or wire c¹ is
passed through suitable loops, hooks or the like c c. These loops or hooks 6 or b
and also c and c² which consist of one or more pieces may be further brought into
various and suitable positions by being bent round such, for instance as shown in
Figures 5, 6 and 7, whilst the shanks, which are fixed in the tooth itself, or even
with or without this latter, the ends of the shank, which lie parallel to the tooth,
are bent round.
If then a tooth Z such as herein before described be inserted in the plate g
Figures 4, 8 to 11, the substance of said plate does not only engage as in the
methods employed previously behind the bent shank, which stands vertically away
from the tooth and is therefore very easily bent straight again, but also as shown
for instance in de and f of Figure 4 behind the shank which lies parallel to the
tooth, whereby the fastening surfaces are very considerably increased in extent as
compared with those formerly obtained, and so distributed in the plate that any
drawing out or breaking off of a single tooth is rendered practically impossible.
The grip or hold obtained by this arrangement may be further strengthened by
soldering or otherwise fastening together the ends of the shanks of the teeth which
lie parallel, to one another, as shown at of Figure 9, or a wire is interlaced.
through the loops b, or a wire c¹ Figure 11 is drawn through the hooks, eyes or the
like cc and soldered at each place of contact on the wire c. In the last mentioned
case an uninterrupted or continuous chain of similar T shaped loops or a network
of the same is formed.

page_text: Having now particularly described and ascertained the nature of my said inven-
tion and in what manner the same is to be performed, I declare that what I
claim is :-
1. A method of fastening artificial teeth in their plates consisting of double
Tshaped loops or hooks of suitable form attached to the teeth in the usual manner,
which loops are inserted in the substance of the plate and bent round substantially
as hereinbefore described and shown on the accompanying drawing.
2. In the method of fastening artificial teeth in their plates by means of T shaped
loops or hooks described in Claim 1, the soldering together of the ends of such
loops with the object of rendering their hold more secure, substantially as described
and illustrated.
3. A method of fastening artificial teeth in their plates, consisting in passing a
suitable wire or wires through lugs or hooks on the shanks or pins of the teeth and
soldering the said wire or wires at each point of intersection, substantially. as
described and shown.
4. A method of fastening artificial teeth in their plates consisting in interlacing
or weaving of a suitable wire or wires with the before mentioned shanks or pins.
and soldering the said wire or wires to these shanks or pins at the points of
intersection substantially as described.
