Application filed March i, 1921.
T 0 all wlwm'z't may concern:
Be it known that I, JOHN YIRIKIAN a citizen of the United States, residing at New York, in the county of New York and State of New York, have invented certain new and useful Improved Vertically-Split Attachments for Removable Dental Bridgework, of which the following is a specification.
My invention relates to an improved vertically split attachment for removable dental bridge work and has for its object to fasten a removabl dental bridge securely .in the mouth by frictional engagement with an anchoring abutment or abutments.
A further object of my invention is to provide an attachment split vertically to vary the frictional engagement as desired but in such a manner that there is no tendency to break .out the side of the inlay in which it is anchored.
A further object of my invention is to provide an attachment in which the frictional engagement with the anchoring abutment be increased or decreased throughout the entire length of the attachment.
Other and further objects of my invention will be apparent from the following descrip-.
tion. and from the accompanying drawings in which Figures 1 and 1 illustrate in perspective the improved vertically split attachment;
Figures 2 and 2 the split tubes in which.
the anchoring members of the attachments are adapted to fit;
Figures 3 and 3 the inlays for the abutment members in which the split tubes are secured;-
Figures 4 and 4 a molar and a bicuspid, respectively, prepared to serve as anchoring abutments and showing inlays, split tubes, and attachments in place;
Figure 5 an artificial bicuspid and molar adapted to replace corresponding natural teeth:
Figure 6 a bridge on which the artificial teeth of Figure 5 are adapted to be mounted and provided with the improved vertically split attachments;
Figure 7 a portion of the jaw with missing teeth and with the abutment teeth prepared to receive theremovable bridge work;
Figure 8 the portion of the j aw illustrated in Figure 7 with the removable bridge work in place;
vantages incident to such structures.
Serial No. 48,847.
illustrative embodiments A, B, F of forms of attachments; and an enlarged view of an attachment showing the manner in which the anchoring member thereof is split. v
It is the practice in high-class mechanical dentistry to secure to natural teeth by frictionally engagin attachments a removable bridge carrying one or moreartificial teeth. One'form ofsuch attachments is shown in my Patent No. 1,218,033, 1917 for cone shaped removable bridge split attachment. 'This old form ofattachment, however,'is in two pieces and has the disad- In the present invention, the supporting member secured to .the bridge is solid and although the anchoring member is split it is secured to or made integral with the supporting member so that the attachment has the advantages of a. unitary structure. There thus is no danger of solder or of gold entering the split while the bridge is being made, and
Figure 9 C, D, E, and Figure 10 although the semi-solid construction enables the frictional contact of the anchoring member to be varied 'the location and direction of the split minimizes the danger of breaking the anchoring abutment, the inlay, or the attachment itself.
In the drawings, reference character 1 indicates the supporting member of the attach-.
merit to which 18 secured or made integral therewith the anchoring member 2 provided with a split 3 which preferably extends substantially vertically the entire length of the anchoring member. It will be noted that the splitis in the plane of the supporting member and thus at right angles to the outer edge and weakest part of the inlay 4:. H the split was parallel to the outer edge of the in-- lay it would tend to break the inlay along that ed e when the split was opened. lWith the split at right angles to the outside edge and parallel to the sides of the tooth, when the split is opened any force exerted. is toward the sides of the inlay protected by the outer covering of the tooth. ltalso will be obvious that if the split extends from top to bottom of the anchoring member, the anchoring member will engage throughout its length with its split tube 6 in socket 5 of the inlay and give a maximum frictional surface for retaining the anchoring member in plane against accidental dis laeement.
Inlay t is secured in abutments T, which ice teeth may be secured W and shape drawings.
to work comprising a solid usually are natural teeth, manner.
The supporting members 1 of the attachments preferably are secured to the support in any desired 5 or bridge 8 on which is mounted the artificial the attachments may Many modifications of my invention will be apparentto those skilled in the art/with out departing therefrom or from the scope of the claims, an invention not being limited to the particular embodiments chosen for purposes of illustration, butcomprising an improved vertically split attachment for removable bridge work adapted to hold the bridge firmly in place abutments and without danger of breaking.
What 1 claim and desire to secure by Letters Patent is:
1. An attachment tor removable bridge supporting member having a substantially vertical portion, and a substantially vertical anchoring member secured to said vertical portion of the supby adjustable fric-' tlonal engagement with an abutment or to be secured rename porting member and adapted to fit within an inlay of an anchoring abutment, said anchorin member being provided with-a substantia ly vertical split extending entirely through the member the plane of the supporting member and at right angles to the outer edge of the inlay whereby it is adapted to engage the inlay in which it is adapted to fit with an adjustable frictional engagement Without danger of breaking any of the cooperating parts.
2. An attachment for removable bridge work comprising a solid supporting member, and an elongated parallel anchoring member secured to said supporting member and split substantially vertically in the plane 0t said supporting member.
- 3. An attachment for removable bridge work comprising a solid supporting member, and an elongated parallel anchoring member secured to said supporting member and split substantially vertically from top to bottom.
4. A removable bridge attachment comprising an inlay with a vertical recess and a supporting member'of two vertical parallel parts one of which is split vertically and the other of which is bent at right angles to the bridge. I
In testimony that 1 claim the foregoing, I-have hereunto set my hand this 23rd day of February, 1921.
Joan manner.
