Patented May 23, 1933 PATENT OFFICE HENRY F. BARSHA, OF LOS ANGELES, CALIFORNIA DENTAL APPLIANCE Application filed July 19, 1932. Serial No. 623,381.
In this specification, and the accompanying drawing, I shall describe and show a preferred form of my invent1on, and specifically mention certain of its more m- 5 portant objects. I do not limit myself to the forms disclosed, since various changes and adaptations may be made therein without departing from the essence of my invention as hereinafter claimed; and objects and advantages, other than those specifically mentioned, are included within its scope.
My invention pertains to appliances for use in the practice of dentistry; and particularly to such as are adapted for art1culating purposes, and for obtammg wax bites. Among its more salient objects are; first, to provide a greatly improved form of device that is adapted for holding art1culating paper-for insertion in the mouth of a patient; second, to provide a device of 'this nature that also is particularly well suited for holding thin sheets of soft wax, for obtaining bites; third, to provide means in such a device for firmly holding other materials, such as emery cloth, in a similar manner, so that, when inserted in the mouth of a patient, he himself may accomplish certain stages of grinding the teeth for articulating purposes, by the muscles of his own jaws; fourth, to providein such a device means for firmly grippin material of various thicknesses, varying from that of a single sheet of tissue paper to that of relative coarse emery cloth; and, fifth, to accomplish the stated and similar objects by means of a very simple, reliable, and relatively inexpensive construction.
My objects are attained in the manner illustrated in the accompanying'drawing, in which- Q Figure 1 is a perspective view of my complete invention, with a specially shaped and relatively thick sheet of material held thereby, readyfor insertion in the mouth of a patient for articulation, grinding, or similar purposes, or for obtaining the bite; and
Figure 2 is a side elevation of the device by itself.
Similar reference numerals refer to similar parts throughout both Views.
As indicated generally above, one of the principal purposes of the device is to secure an accurate knowledge of the relationship and relative position of the maxillary and mandibular teeth, for locating the high 5,, spots for the purpose of milling them. It is especially important to be able to accomplish this means of checking high spots in artificial dentures, whether complete plates, inlays, 0r bridges. It also is highly desirable to be able to check the entire month of a patient with one application of the recording material, in this manner. Heretofore this has been very difficult to accomplish, and has required great skill to prevent the recording material from becoming rufi'ied, twisted, or otherwise distorted, in applying it to, and removing it from, the mouth of a patient.
In order to secure the best results, it often is desirable for such purposes touse ma terial of different thicknesses, or in superposed plural layers, in a number of steps, completing the process by using a very thin sheet of material for obtaining the finished results.
In addition to the preparation of artificial dentures, similar methods may be employed for correcting the bite of pyorrhea patients.
In other cases of dental practice, it is necessary to obtain an accurate bite of a patient in wax, in centric occlusion. In such cases a sheet of wax commonly is used, and it is highly desirable to provide means 5 for holding the wax without distortion, in such a manner that the patient, in biting, can bite clear through the wax. It is particularly desirable for such purposes to have suitable holding means, especially when the wax sheets are to be rendered soft by heatmg.
It will appear from what has been said, and indeed it is a matter of common knowledge, that any appliance that is to be used for such purposes as those mentioned, must be both light and strong, and approximate the shape and dimensions of the natural dental arch of the patient in whose mouth it is to be used. It is also well understood that, in these operations, satisfactory results cannot be obtained without providing ample space for the patients tongue, since otherwise the resulting record will be more or less unnatural and distorted.
In view of the foregoing, I prefer to construct that portion of my appliance that is to be inserted in the mouth, in an arcuate form, roughly approximating the shape and dimensions of the natural dental arch of the patient, but somewhat larger than it. The device must be capable of firmly gripping material of various thicknesses,and be provided with a manipulating handle extending from the central part of the are.
A preferred form of my invention, selected for illustration, is made wholly of wire, of German silver or other suitable material, and of the proper gauge for securing the necessary mechanical strength. It comprises a lower forked member, having a handle 5 and a pair of tines 6. At the extremity of each 'of these tines, is an upstanding ear 7, adapted to form the leaf of a hinged joint; and a similarly shaped upper forked member, having a similarly dimension'ed pair of tines 8, and a backwardly extending arm 9. The extremities of the tines of the upper forked member are pivotally "connected to cars 7 at 10. An encircling ring 11 is adapted for being slipped over arm 9, so as to hold it in contact with handle 5.
I prefer to construct the upper and lower members of my device in such a manner that the opposed tines are slightly convex with respect to each other, so that, when closing pressure is applied by means of ring 11, the opposed pairs of tines will be firmly in contact and capable of exerting strong pressure against each other for gripping purposes. I also prefer to form arm 9 in such a manner that it is adapted to act in the manner of a wedge, so that the grip of the tines may be progressively tightened as the ring 11 is pushed up.
When the device described is closed, it will appear inside elevation as indicated in Fig. 2. The opposed tines, that in open position are convex with respect to each other, will become flattened out in contact by the action of ring 11, as indicated at 12. The wedge construction of arm 9, to permit this to be done, is clearly indicated in Fig. 2.
In the use of my device, I prefer to cut such material as articulating paper, emery cloth, or wax sheets, into horseshoe form, as indicated at 13. The resiliency of the material of the tines, and of arm 9, makes it possible to obtain a strong grip upon the interposed material, throughout practically the Whole extent of its periphery; and this grip ping action is exerted upon the material without in any way distorting it. The
horseshoe shape of the material provides v claim ample space for the tongue, so that natural records may be made by the patient.
It is preferable to construct ears 7 as integral parts of the lower member of the device, and to have the upper tines pivoted thereto. In this manner the tines, in closing, have to come together in proper relation, and there will be no tendency for the gripped material to be buckled or shifted during the clamping.
Having thus fully described my device, in a manner that Will be readily understood by those familiar with the art involved, I
