2 Claims. (Cl. 32-5)
This invention relates to attachments for arti
lever 2. The sleeve 1 is also preferably formed
?cial teeth ?xed in a vulcanite-bed in a kind of with a knob H which is adapted to be engaged
bridge work, and has for its object to provide by the tip of a ?nger or a suitable tool so as to
means for retaining the arti?cial teeth in posi
move the sleeve on the holder 8.
‘ 5 tion in the mouth. The device is simple in con
When arranging the arti?cial teeth in the
struction, low in cost, easy in application and mouth, the lever 2 is positioned substantially ver
reliable in function, by which sound teeth used tically as shown in Fig. 3, and consequently the
as piers need not be arti?cially crowned and are
not influenced by the forces set up in chewing
with the arti?cial teeth.
Other features and objects of the invention
will be apparent to those skilled in the art upon
a consideration of the following description and
the accompanying drawing wherein several ex
15 emplary embodiments of the invention are
disclosed.
In the accompanying drawing:—
‘
Fig. 1 is a perspective view of an attachment
according to the invention.
Fig. 2 is a plan view of the attachment, illus
trating the same applied to a pier tooth.
Fig. 3 is a perspective view of the attachment
embedded in a vulcanite-bed of arti?cial teeth,
illustrating the position of the parts at the time
25 When it is to be applied to its place in the mouth.
Fig. 4 is a perspective view of the attachment
as shown in Fig. 3, illustrating the position of
the parts when it is applied to its place in the
mouth.
Fig. 5 is a view similar to Fig. 2 illustrating a
30
modi?cation of the attachment.
Referring to the drawing, I represents a clasp
intended to be placed on the cheek side of a pier
tooth. The clasp is connected with a lever 2 by
3 .means of a cross member 3 which is provided
with a lug 4 adapted to engage against an under
cut of the crown of the pier tooth. The cross
member 3 carries an anchoring member 5 mov
ably mounted thereon and adapted to be em
40 bedded in the vulcanite-bed of the arti?cial teeth.
The anchoring member 5 is formed with a tongue
6 having an incline formed by bending the lat
eral portion of said anchoring member on the
side adjacent the lever 2, which co-operates with
45 the lever 2, when the arti?cial teeth are put in
position in the mouth, to cause the clasp I to be
pressed against the cheek side face of the tooth
used as a pier, tending to thrust the lever 2 to
ward the tongue side.
50
1 represents a sliding sleeve mounted on a
holder 8 with toes 9 which are adapted to be em
bedded in the vulcanite-bed of arti?cial teeth.
The sleeve 1 is thus held in such a position as to
be moved over the free end of the lever 2 when
55 the arti?cial teeth are arranged in position in
the mouth. The sleeve 1 is formed with a clip
III at one end for engaging the free end of the
clasp I and the lug 4 are in an approximate ver
tical position. When the arti?cial teeth set is
put in position in the mouth, the lever 2 is turned 10
until it lies along the holder 8 and then the sleeve
‘l is moved on the holder over the free end of the
lever 2. In this position of the lever 2, the clasp
l is in ?rm engagement with the cheek side face
of the pier tooth, and the lug 4 is in engagement 15
against the undercut of the crown of the pier
tooth, whereby the arti?cial teeth set is secured
in position in the mouth.
If desired, the clasp I may be replaced, a clasp
la embedded in the vulcanite-bed of the arti?cial 20
teeth and in this case, the tongue 6 may be
omitted, as shown in Fig. 5 since the function
thereof is not necessary in this modi?cation.
Having now particularly described and ascer
tained the nature of my said invention and in
What manner the same is to be performed, I 25
claim:——
1. An attachment device for arti?cial teeth
comprising, a clasp for gripping a pier tooth, a
lever connected with the clasp by means of a
cross member, a lug carried by the cross member 30
adapted to engage an under-cut of the crown of
the pier tooth, a vulcanite-bed having arti?cial
teeth set therein, an anchor member ?xed to the
vulcanite-bed rotatably supporting the cross
member, an inclined tongue, said lever engaging
the tongue on movement thereof to cause ‘the
clasp to be urged against the pier tooth, a holder
?xed'to the vulcanite-bed and a sleeve slidably
mounted on the holder adapted. to be moved over
the free end of the lever for securing the lever 40
in a position along the holder.
2. An attachment device for arti?cial teeth
comprising, a vulcanite-bed having the arti?cial
teeth set therein, a clasp supported by the vul
canite-bed for gripping the pier tooth, a cross
member having a lug adapted to engage an
under-cut of the crown of the pier tooth, means
for rotatably supporting said cross-member on
the vulcanite-bed, a lever ?xed to said cross 50
member, a holder having the ends thereof em
bedded in the vulcanite-bed, and a sleeve slid
ably mounted on the holder adapted to be moved
over the free end of the lever for securing the
lever in a position along the holder.
