Improvements in connection with Artificial Teeth.
I, MAX TRESENREITER, of 2, Sonnenstrasse, Munich, Germany, Manufacturer of
Artificial Teeth, 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:-
My invention relates to improvements in connection with artificial teeth and
the object is to provide means for attaching these teeth to the stumps or roots of
the natural teeth and without necessitating the use of rivets, screws and similar
inconveniences commonly employed for the purpose. The invention is applicable
to all kinds of teeth, whether with large or small cavities and whether having
straight or other roots.
In carrying my invention into effect I proceed in or in about the following
manner, making reference to the accompanying drawing in which Figs. 1 and 2
are vertical sections, the former of a grinder (molar) tooth and the latter of an eye
(corner) tooth. I provide a piece of bent metal a of spring like character, roughed
outside and preferably in the form of a plate and having outwardly turned ends a'.
In using this contrivance the top of the stump of the tooth is filed level and the
cavity provided with indentations b if they do not exist naturally. The cavity is
carefully cleaned out and partly filled with a suitable anti-septic. The bent piece
of metal a is then filled with a suitable dental cement and placed in the cavity,
the "bend" standing above the top of the stump and the ends a¹ engaging with
the indentation within the cavity. The space between the piece a and the wall
of the cavity is then also filled with dental cement. The cavity of the artificial
tooth is filled with dental cement and pressed over the upstanding bend of the
piece a which becomes a core, the roughened exterior of which keeps hold of the
cement in the cavity and this cement is prevented from coming out of c by the
in-turned rounded part d provided round the mouth of the cavity of the artificial
tooth.
The invention is applicable to sets of teeth as well as to a single tooth and pro-
vides an extremely secure mode of attaching artificial teeth to natural stumps or
roots. Although more especially useful in dealing with the grinding (molar) teeth,
it is nevertheless as already mentioned applicable to all kinds of teeth.
my
Having now particularly described and ascertained the nature of
invention, and in what manner the same is to be performed, I declare that what
said
I claim is:-
1. The improved method of attaching artificial teeth to natural stumps or roots,
the said method consisting essentially in cementing into the cavity of the stump
a piece of spring like metal having a roughened outer surface, the said piece of
metal being bent on itself but not into contact and having its free ends outwardly
turned so as to engage with the naturally or artificially roughened or indented
nterior of the cavity of the stump, the artificial tooth itself having a cavity at
ts base, which cavity is filled with dental cement and pressed down over the bend

top of the stump, the edge of the mouth of the cavity of the artificial tooth being
in-turned to prevent the cement therein from coming out, the whole substantially
as described in the above specification and exemplified in the accompanying draw-
ing.
The application of the invention claimed in the above Claim 1 to sets or
rows of artificial teeth substantially as described.
3. The improved method of attaching artificial teeth to natural roots or stumps
provided for and operating substantially as described in the above specification
and exemplified in the accompanying drawing.
