DENTAL PARTIAL PLATE HOLDER Filed Jan. 26, 1959 Elwin lire Patented Jan. 16, 1940 UNITED STATES PATENT OFFICE DENTAL PARTIAL PLATE HOLDER Charles D. Kreps, Hazel Crest, Ill.
Application January 26, 1939, Serial No. 252,989 .3 Claims. (01. 32-5) This invention relates to a denture device or means whereby partial plates may be removably but securely secured to a live tooth and efficiently supported. g i
It is further aimed to provide a structure having a bar or the like disposable behind teeth and with a clamp means extending therefrom to coact with a live tooth.
The more specific objects and advantages will become apparent from a consideration of the description following taken in connection with the accompanying drawing illustrating an operative embodiment.
In said drawing:
Figure 1 is a view in front elevation showing the improvement in use;
Figure 2 is a plan view of the improvement, a live tooth being shown in cross section;
Figure 3 is a vertical section taken on the line 33 of Figure 1;
Figure 4 is a plan View of the parts minus the teeth; r Figure 5 is a view in front elevation of the parts of Figure 4; and
Figure 6 is a fragmentary front elevation of a portion of the artificial tooth or teeth employed.
Referring specifically to the drawing wherein like reference characters designate like or similar parts, the improvements may be employed in connection with either upper or lower teeth. A metallic bar I is provided of a width less than the height of .the teeth, that is the natural teeth of the user, and the same is disposed behind the teeth, being arcuate or having a deflected portion as at H, enabling abutting contact of the bar with at least one live tooth of the user as at l2, it being understood, that the bar may abut any desired number of teeth. An artificial tooth member i3, is vulcanized to the bar 10 and this member may represent a single tooth or any desired number of teeth, according to the removed natural teeth, such tooth member I3 preferably being concave as at M in its upper edge, to intimately fit and have suctional contact with the gum.
Extending forwardly from the bar I0 is a stud l riveted or otherwise rigidly fastened to the bar as at [6. It will be noted that the artificial tooth member l3 has a notch I! at one end which receives the stud I5 and thus offers great support and reinforcement to the tooth member, 9
especially when biting. A bar or plate l8 of suitable size overlaps the artificial tooth member I3 and the naturaltooth l2 and the structure is rigidly clamped to the natural tooth l2 by the bars H and I8, through the action of a screw 19 threaded through bar l8 and into the stud as at 20, said screw having its head 2| finished in any desired manner, countersunk, if desired, or otherwise.
It will be obvious, that Where conditions warrant or it is desired, more than one of the plates I8 and associated parts may be used, according to the position of the natural teeth in the mouth of the patient and the artificial teeth to be used on the bar. I
Various changes may be resorted to provided they fall within the spirit and scope of the invention.
I claim as my invention:
1. A dental device of the class described comprising a bar, a stud projecting forwardly from the bar, a plate spaced from the bar by said stud, screw means securing the plate to the bar, artificial tooth means clamped to the bar by one end portion of the plate under the action of the screw means, the plate at the other end portion extending beyond the tooth means and adapted jointly with the bar and screw means to clamp against opposite faces of a tooth.
2. A dental device of the class described comprising a bar, a stud projecting forwardly from the bar, a plate shorter than the bar spaced from the bar by said stud, screw means securing the plate to the bar, artificial tooth means clamped to the bar by one end portion of the plate under '35 the action of the screw means, the plate at the other end portion extending beyond the tooth means and adapted jointly with the bar and screw means to clamp against opposite faces of a tooth, said artificial tooth means at one end having an open notch interfitted with the stud.
3. A dental device comprising a bar, a stud extending therefrom, artificial tooth means on the bar interfitted with the stud, a plate bearing against the free end of the stud projecting beyond one end of the tooth means to coact with the bar for clamp engagement with a natural tooth, and a securing screw extending through the plate and engaging said stud.
CHARLES D. KEEPS.
