PROVISIONAL SPECIFICATION.
Improvements in or in connection with Screws for Inserting in
the Teeth in Dentistry.
I, ALFRED BOWMAN-SMITH of "Shandon " Alexandra Road, Reading, in the
County of Berks, Pharmacist, do hereby declare the nature of this invention to be
as follows:-
This invention relates solely to dentistry.
وو
Heretofore in inserting or attaching stopping or filling or "artificial crowns
in decayed or partially decayed teeth-very fine screws (known as "anchor"
screws) have been inserted by screwing same into a hole bored or formed for this
purpose in the tooth or in that part of it known as the "dentine" which screws
owing to their smallness and the inaccessibility of-or difficulty of applying same
to the said hole in the said tooth have therefore usually been held in a kind of
tube or sleeve and while held and guided by this appliance then a fine screw-driver
has to be passed up said sleeve into a cross-cut in the head of the screw and thus
the latter is screwed into the desired position with much difficulty and trouble and
requiring both hands of the operator to manipulate these instruments.
Now my invention is designed to dispense with the use or necessity of either the
screw-driver or sleeve or other separate screw holder while inserting said screw in
position.
My present invention is as follows:-
:-
I form a screw thread in any suitable manner upon a fine rod or wire of any
suitable material for instance gold and platinum alloy or iridio-platinum or other
suitable metal or alloy and of a length sufficient for my purpose (say two or three
inches or more or less) and at or near one end I fatten or extend same or form or
mount wings or a projection or projections thereon or other suitable means (or
same may be otherwise suitably arranged) so as to afford a ready means of turning
this screw by the hand (fingers) of the operator without requiring any screw-
driver for this purpose.
Thus when using my invention in stopping etc. teeth-the hole or holes are
formed in the tooth or dentine as before (or in any other suitable manner) and
tapped if desired and then the operator takes my long dentine screw (as I term it)
and the point thereof can be quickly and easily inserted in the prepared hole and
then (when it has been screwed therein sufficiently tightly) with a pair of wire
nippers or dental engine or other suitable cutters a length of the screw portion can
be cut off or otherwise severed leaving an end projecting from the tooth or hole
of sufficient length as required.

the Teeth in Dentistry.
I, ALFRED BOWMAN-SMITH of "Shandon," Alexandra Road, Reading, in the
County of Berks, Pharmacist, 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:-
This invention relates solely to dentistry.
Heretofore in inserting or attaching stopping or filling or "artificial crowns" in
or to decayed or partially decayed teeth, very fine screws (known as "anchor"
screws) have been inserted by screwing same into a hole bored or formed for this
purpose in the tooth or in that part of it known as the " dentine
"which screws
owing to their smallness and the inacessibility of-or difficulty of applying same
to the said hole in the said tooth have therefore usually been held in a kind of
tube or sleeve and while held and guided by this appliance then a fine screw-driver
has to be passed up said sleeve into a cross-cut in the head of the screw and thus
the latter is screwed into the desired position with much difficulty and trouble
and requiring both hands of the operator to manipulate these instruments.
Now my invention is designed to dispense with the use or necessity of either the;
screw-driver or sleeve or other separate screw holder while inserting said screw in
position.
My present invention is as follows :-
I form a screw thread in any suitable manner upon a fine rod or wire of any
suitable material for instance gold and platinum alloy or iridio-platinum or other
suitable metal or alloy and of a length sufficient for my purpose (say two or three
inches or more or less) and at or near one end I flatten or extend same or form or
mount wings or a projection or projections thereon or other suitable means (or
same may be otherwise suitably arranged) so as to afford a ready means to grasp.
or turn this screw by the hand (fingers) of the operator without requiring any
screw-driver for this purpose or sleeve to guide or hold same during insertion.
Thus when using my invention in stopping etc. teeth-the hole or holes are
formed in the tooth or dentine as heretofore (or in any other suitable manner) and`
tapped if desired (advantageously of the exact size of the dentine screw) and then
the operator takes my long dentine screw (as I term it) and the point thereof can
be quickly and easily inserted in the prepared bole and then (when it has been
screwed therein sufficiently tightly-by the aforesaid handle or means to grasp.
same) with a pair of wire nippers or dental engine bur or other suitable cutters a
length of the screw portion can be cut off or otherwise severed leaving an end
projecting from the tooth or holes of sufficient length as required while the
remainder can be used again and again till the total length thereof has been
used up.
My invention is illustrated in the accompanying drawings in which:
Fig. 1 shows (on an enlarged scale) a dentine screw A with a flattened end or
loop A' on one erd thereof by which to grasp and turn said screw.
Fig. 2 is a view (on a similar enlarged scale) of a screw A with a cross-bar or
handle A thereon by which to turn same.
Fig. 3 shows (also on a similar scale) a length Ax divided from said screw A
which latter will serve to form a number of such lengths A* which are respectively
only cut off or divided from the main part A after insertion of the end of the
latter in the desired position in the tooth.
These screws may be used for fillings, contouring work, crown attachments, etc.

page_text: Having now particularly described and ascertained the nature of this inven-
tion and in what manner the same is to be performed I declare that what I
claim is:-
1. The combination with a screw suitable for dividing into several lengths for
use in dentistry of means provided on one end of and integral with said screw by
which to grasp and screw same into the tooth without the aid of any screw driver
cr sleeve substantially as and for the purposes set forth.
2. The improved dentine screw constructed combined and arranged to act
substantially in the manner and for the purposes herein before described and
illustrated by way of example in the drawings hereunto annexed.
