Description

Nov. 18, 1952 v. P. HENDRICKS ARTIFICIAL TEETH Filed May 2, 1949 Jim; 1.
Patented Nov. 18, 1952 UNITED STATES PATENT OFFICE ARTIFICIAL TEETH I Victor P. Hendricks, Pomona, Calif. "Application May 2, 1949, Serial No. 90,940 10 Claims. ('01. 1321-2) 1 My inyention relates to improvements in amii'icialteeth, and particularly to improvements in the assembly and construction of dentures; and the objects of my invention are, first, to provide an anchor frame adapted to receive and anchor a full set .of upper and lower teeth; second, to
afford facilities in such anchor frame to adjust each individual tooth horizontally in its relation to neighboring teeth without disturbing the pre set occlusion between upper and lower teeth; third, to provide means for assembling dentures so that a full set of either upper or lower teeth is arranged as a unit or divided into any number of segments, as a manufacturer or dentist may desire; fourth, to construct a frame for prosthetic dentures in which each tooth may may easily be removed or replaced without disturbing the residual denture; and fifth, to provide an anchor frame for prosthetic dentures which simplifies the manufacture of dental plates, reducing at the same time the costs of manufacture and time'reguired to produce them, and giving additional stability and strength to the finished product.
i I attain these and other objects by means of the construction and arrangement illustrated in the accompanying drawing, in which- Figure 1 is a front elevational View of a full set of upper and lower teeth using my anchor frame, and in a flat position;
Figure 2 is a plan view of a set of lower teeth using my anchor frame, in a curved position;
Figure 3 shows an elevational rear view of a molar tooth having a slot for receiving my anchor frame;
Figure 4 is a cross-sectional view of the molar tooth on line d l of Fig. 3;
Figure 5 is an elevational view of a molar tooth showing a portion of my ancho frame and the method by which said tooth is attached to said am Figure 6 is an enlarged fragmentary view in perspective of my anchor frame showing part of an upper anchor band for the attachment of molar teeth and segments for the attachment of front teeth;
Figure 7 is a side elevational view of one of the upper front teeth showing a portion of my anchor frame, and the method by which said tooth is attached to said frame; and
Figure 8 is a cross-sectional view of the upper front tooth on line -8--8 of Fig. 7.
Similar numerals refer to similar parts throughout the several views.
Referring to the accompanying drawing, wherein for the purpose of illustration I show a preferred embodiment of my invention, vmy
anchor framecomprises the upper anchor band 10, the lower anchor band II, and two stability bars [2, I2, which connect the free ends of the anchor bands and holds said anchor bands in a spaced parallel relation.
Each anchor band consists of two identical fiat strips of rigid material l4, l4. and l5, l5, respectively, and a plurality of frame segments for upper teeth 16, and for lower teeth [1, respectively, which segments are hinged to each other and to said "respective flat strips, l4 and [5 respectively, by the use of pivots l8.
Each flat strip, M and [5 respectively, carries transversely a number of ribs 19, spaced from each other a distance approximating the lateral width of an average molar tooth, which said ribs are rigidly afiixed to the upper fiat side of the upper fiat strips l4, and to the under side of the lower flat strips I5.
Stability bars 12, [-2, connect the underside of the upper fiat strips 14, to the top side of the lower flat strips 15, near the free ends of said fiat strips.
The other end of said fiat strips is pivotally connected to frame segments, l6 and I! respectively, by means of pivot 18 in such a way as to permit limited horizontal motion to the frame segments andxto. the fiat strips respectively.
'Each upper frame segment 16, and lower frame segment I1, consists of a pair of fiat bars 20, 20, rigidly affixed at one end to -a horizontally placed semi-circular rod 22,, extending outwardly and near the free ends of said rod in linear relation to each other. The other end of each flat bar 29, -20, rests upon, or is supporting flat bars of neighboring frame segments or fiat strips, and is pivotally connected thereto by pivots l8, and are forming, what I name an interproximal hinge 29.
Front tooth guide rods 23, are rigidly affixed to each free end of the semicircular rod 22, in a substantially vertical position and at right angles to said semicircular rod. The exact point of attachment of each guide rod to the ends of each semicircular rod varies with the relative horizontal position of each pair of fiat bars 20, 20, depending upon whether each of such fiat bars rests on the top of, or acts as support for, the flat bar of its neighboring element to which it is pivotally connected. I
Such neighboring element may either be an-'- other segment, a d]? respectively, 'or a flat strip, l4 and respectively, I m i 5 For the purpose of this invention I use arti ficial molar teeth 24, having a slot 25, which extends from the rear of each tooth near its upper portion transversely across the whole width to approximately the center of each tooth.
For the purpose of this invention I use artificial front teeth 26, having a pair of substantially vertical grooves 21, 21, in the rear portion of each tooth, adapted to receive guide rods 23, 23, and having a substantially curved semicircular rear portion 28, suitable to fit snugly into the space provided by semicircular rod 22.
The length of the stability bars I2, I2, is designed to hold upper and lower anchor bands, Ill and II respectively, in horizontally spaced relation so as to provide a fixed pre-set occlusion between the upper and lower dentures.
In use, each molar tooth 24, is slid into position on the fiat strips, I4 and I 5 respectively, between any two adjacent ribs I 9, I 9. The thickness of each slot 25, is designed to fit each molar tooth 24, snugly on said fiat strips. After the assembly of the molar teeth is completed, each upper front tooth 26, is pushed upwards into position in each frame segment IS, the grooves 21, 21, and curved rear portion 28, of each front tooth being designed to fit tightly in the space provided by the semicircular rod 22, and vertical guide rods 23, 23. Each lower front tooth is then pushed downwards into position and anchored in the lower anchor band segments in the same manner as heretofore described for the upper front teeth.
The length of the stability bars I2, I2, is designed to provide a pre-set occlusion, as hereinbefore described, and the only adjustment needed ordinarily to manufacture a custom-made denture is theadjustment in the relative horizontal position of each front tooth. This adjustment is effected by the horizontal movement of each of the segments carrying the front teeth by means of the interproximal hinges, so-called because they are located in the interproximal space between front teeth. These interproximal hinges 29,29, consist of the flat bars 20, 20, of each segment and its adjoining segment or fiat strip respectively, and pivot l8, as heretofore described.
'If it should become necessary to change the occlusion of any upper front tooth, for example, from its pre-set position, this may be accomplished by cementing such tooth into the segment in the desired spacial relation to its mate in the lower denture.
After all teeth are fixed in their desired horizontal and vertical relative position to each other, the stability bars I2, I2, are cut and removed from the anchor frame I, and standard procedure is followed from thereon in completing the denture.
In case any particular tooth breaks during use of the dentures, or needs replacement for any other reason, such tooth may be removed from its position on the anchor frame I, and replaced without disturbing any other tooth in the denture.
While a specific form of my invention has been described, it is understood that the same may be modified without departing from the spirit of my invention as defined in the appended claims.
