1, HENRY JAMES MILLER, of 16, Rue de la Monnaie, Paris, in the Republic of
France, Dentist, do hereby declare the nature of this invention to be as follows:-
It is known that artificial teeth, of the variety known as nineral teeth, are
made from porcelain paste, in which two pins or lugs of platinum are placed
and rendered solid therewith by baking.

It has heretofore been usual, before mounting the teeth on the dental plates,
to bend the pins" or lugs with pliers: now the movement the "pin" or lug
undergoes during this operation is liable to split the porcelain all round the
"pins or lugs and it is one of the principal causes of complete rupture of the
tooth, since the tooth, having thus an incipient crack, finishes by splitting com-
pletely by reason of the expansion caused by the heat in soldering it or also by
the shocks produced in mastication.
I have mentioned above that the tooth, in order to fix it on the mount, was
provided with a metallic plate which is only laid against the tooth; now this
plating does not increase the solidity of the tooth and leaves between the tooth
a space in which foods can lodge and putrefy.
It will therefore be seen that teeth thus mounted do not show all the solidity
that is to be desired and that the dental plates are not perfect when regarded
from a hygienic point of view.
To obviate these inconveniences I have invented a new class of mineral teeth.
In order that I may be readily understood I have shown in the accompanying
drawing which is given by way of example only, the arrangement forming the
object of my invention.
Figure 1 shows a vertical transverse section of an incisor tooth prepared
according to my said invention.
Figure 2 shows a vertical transverse section of a molar tooth.
Figure shows the exterior and the plan of a molar tooth.
Figure shows vertical sections of two molar teeth provided with lateral

Figure shows a vertical section of an incisor tooth also provided with notches.
As shown in the drawing, the tooth a is joined on to a plate or exterior lining b,
as in Figure 1, or to an interior lining c. as in Figure 2.
To effect this I proceed as follows, riz:-
.
In a plate of metal, in any convenient manner, I carve out or recess a part
corresponding to the shape of the tooth one of the faces of the metal is pro-
vided with projections which can be produced at the same time as the carving
or recessing or in any other suitable manner.
On the face that carries the projections I apply the paste to form the tooth
and I then submit the whole to baking in an oven at a high temperature.
The tooth is thus in some degree cast or incorporated with the metal and forms
only one and the same body.
By my improved process of manufacture there is not therefore any space be-
tween the tooth and the metallic plating, thus giving it a great resistance.
The tooth thus produced can be soldered in the ordinary way on the metallic
dental plate or case.
..
In order to avoid splitting of the tooth by the heating and cooling I can
provide it with an exterior metallic plating on three of its faces, as shown in
the molar tooth, Figure 3, by proceeding as above described.
When it is desired to employ a mounting of plastic material, the exterior face
of the metal plate can be provided with “pins or lugs which are let in flush
in the " case or mount in the ordinary way.
"
For pivot teeth, the tooth is covered inside with a plating or coating of
metal applied in any convenient manner and united to the tooth by baking as
above described.
After having placed the pivot in the root of the tooth of the patient under
treatment, the mineral tooth is adjusted without having to consider the position
of the pivot. The tooth being adjusted on the root, it can be withdrawn with
the pivot cemented to the interior, and afterwards it can be soldered by means
of metal or other suitable material.
A tooth mounted on a pivot is thus provided having extreme solidity.
When molar teeth are soldered onto a metallic mount the teeth do not present
great solidity if pressure is exercised in a transverse direction on the mount.
In order to render the molar teeth more stable the cavity of the tooth in
which the metal is run is provided with lateral notches e in which a metallic
bar can be placed for uniting the teeth, the metal, at the time of pouring, running
from one tooth to the other in these notches. In this manner the teeth are made
solid one with the other, as shown in Figures 4 and 5.
It is of course understood that the metallic lining of the tooth, either when
exterior or interior, can be provided with points or other projections, obtained by
any convenient process or even openings in which the materials which constitute
the tooth can lodge in such a manner as to join onto the plating when baked.

To obviate these inconveniences I have invented a new class of mineral teeth.
In order that I may be readily understood I have shown in the drawing filed
with my Provisional Specification, which is given by way of example only, the
arrangement forming the object of any invention.
Figure 1 shows a vertical transverse section of an incisor tooth prepared
according to my said invention.
Figure 2 shows a vertical transverse section of a molar tooth.
Figure 3 shows the exterior and the plan of a molar tooth.
Figure 4 shows vertical sections of two molar teeth provided with lateral
notches.
Figure 5 is a plan view of the same.
Figure 6 shows a vertical section of an incisor tooth also provided with notches.
As shown in the drawing, the tooth is joined on to a plate or exterior lining b,
as in Figure 1, or to an interior lining e, as in Figure 2.
To effect this I proceed as follows, iz:
-
In a plate of metal, in any convenient manner, I carve out or recess a part
corresponding to the shape of the tooth; one of the faces of the metal is pro-
vided with projections which can, be produced at the same time as the carving
or recessing in any other suitable manner.
On the face that carries the projections I apply the paste to form the tooth
and I then submit the whole to baking in an oven at a high temperature.
The tooth is thus in some degree cast or incorporated with the metal and forms
only one and the same body.
By my improved process of manufacture there is not therefore any space be-
tween the tooth and the metallic plating, thus giving it a great resistance.
The tooth thus produced can be soldered in the ordinary way on the metallic
dental plate or "case."
In order to avoid splitting of the tooth by the heating and cooling I can
provide it with an exterior metallic plating b on three of its faces, as shown in
the molar tooth, Figure 3. by proceeding as above described.
When it is desired to employ a mounting of plastic material, the exterior face
of the metal plate can be provided with pins" or lugs which are let in flush
in the case or mount in the ordinary way.

of the pivot. The tooth being adjusted on the root, it can be withdrawn with
the pivot cemented to the interior, and afterwards it can be soldered by means

A tooth mounted on a pivot is thus provided having extreme solidity.
When molar teeth are soldered onto a metallic mount the teeth do not present

exterior or interior, can be provided with points or other projections, obtained by
any convenient process or even openings in which the materials which constitute
the tooth can lodge in such a manner as to join on to the plating when baked.
Having now particularly described and ascertained the nature of my said
invention and in what manner the same is to be performed, I declare that what
I claim is—
The manufacture of improved artificial teeth in which the paste forming the
tooth or teeth is applied to a lining of metal provided with projections or open-
ings, in such a manner as to become solid therewith by baking, substantially
as herein before described with reference to the drawing, for the purposes
specified.
