Definitions

  • ABSTRACT A frame for taking bite impressions for making partial teeth prosthesis, extensions of prosthesis, crowns and bridges and the like, wherein at least one frame is used which runs parallel to the row of teeth for receiving bite impressions, and includes a plurality of retaining elements coupled to the frame for retaining the material which takes the impressions.
  • This invention relates to a frame for taking bite impressions for producing partial artificial teeth, prosthesis extensions, crowns and bridges.
  • a correct fitting of the bite block is necessary, in order to make a good fitting prosthesis, because the fitting of the bite block defines the position and height between the upper and lower jaw of the teeth prosthesis.
  • the patients natural teeth are imprinted into the wax layer of the bite blocks which are inserted into the patients mouth.
  • the bite blocks are removed from the patients mouth and are then mounted onto the working models and brought into occlusion.
  • the working models as well as the bite blocks are then returned to the technical laboratory.
  • the technician mounts the working model on the articulator, removes the bite blocks and sets up the teeth.
  • the finished teeth prosthesis is then returned to the dentist for fitting in the patients mouth.
  • the dentist can determine whether or not the bite was taken correctly, and whether the technician has correctly positioned the working models on the articulator.
  • the teeth prosthesis should fit perfectly, and only cosmetic improvements should be necessary, that is, the shape of the artificial teeth.
  • the teeth prosthesis are made right away. Therefore, a test fitting as well as the occlusion, which would show the correct setup of the teeth prosthesis is eliminated.
  • the present invention provides an improved device for the taking of the bite. This is achieved by eliminating the making of a bite block so as to shorten one step in the making of a teeth prosthesis.
  • at least one frame is provided which runs parallel in front of the row of teeth. This frame is provided with retention elements for the imprint material when the bite is being taken.
  • the frame for taking the bite imprint is advantageous in that it provides a correct occlusion, which could not be obtained by the old method in using a bite block.
  • Another advantage is that the dentist, after taking the bite impression, can immediately take the bite. This saves the patient another visit to the dentists office.
  • the present method eliminates the making of a bite block. If the patient needs an upper and lower jaw teeth prosthesis, an impression would have to be taken from v the patient, in order to produce a working model. Since, with the new method, the bite impression is filled up only on one side, the remaining opposite bite impression would serve as the counter model. Since the novel frame for taking the bite impression is filled up with the impression material, it is a lot easier for the patient to bite into it, than into the wax layer of the bite blocks. The dentist can now send the bite impression frame to the laboratory for making the working model, and is assured that the bite impression cannot be damaged, a defect which frequently happens with conventional bite blocks. The bite impressions show clearly the natural teeth of the patient in the upper and lower jaw. Furthermore, the gaps of the missing teeth and they gum line are also clearly shown. The bite impressions taken with the novel frame, facilitates the exact occlusion and the technician no longer has any difficulties placing the working models into the articulator.
  • the frame for taking the bite impressions has a frame portion which runs in front of the row of teeth.
  • the retaining elements for the impression material in this embodiment are arranged as free carrying webs, which can be easily broken off.
  • the webs may also be arranged in such a manner in that they are freely movable in the frame.
  • This embodiment is advantageous in that application of this frame is extremely simple.
  • the dentist would either break off the webs at the places where the patient still has his natural teeth, or just move the webs out of the region of the natural teeth. The remainder of the webs are then covered with'impression material and shown the correct occlusion, after taking the bite.
  • a further advantage is that only the gaps between the natural teeth are filled with impression material and the natural teeth stay free of such material.
  • the bite frame for taking the bite impressions described in this embodiment is particularly advantageous for making partial teeth prosthesis, or extensions of a prosthesis.
  • the webs and the frame parts may be made and delivered separately to the dentist. The dentist could then assemble the frame and the webs to the needs of the individual client.
  • the bite impression frame is provided as a crescent shaped frame, that is, it only extends halfway around the paitients jaw.
  • a crescent shaped frame is advantageous for taking bite impressions for bridges, and crowns.
  • Another advantageous feature is that these crescent shaped frames are made disposable and need not be returned for cleaning.
  • a small handle is provided in on the frame which facilitates the insertion of the frame into the mouth of the patient.
  • FIG. 1 is a plane view of the bite impression frame shown with webs according to the invention
  • FIG. 2 shows a second embodiment of the invention
  • FIG. 3 shows a variation of the second embodiment in a cross-sectional view taken along lines A-B of FIG. 2.
  • FIG. 1 there is shown a frame for taking bite impressions together with webs 60 which are arranged between frame portions 1 and 2.
  • the webs are preferably slightly arched so that they can be more easily broken off, if required.
  • Frame portions 1 and 2 are connected by webs 3 disposed on the outer ends of the frame portions.
  • Frame portions 1 and 2 are preferably arranged in the same plane.
  • Frame portion 2 runs at the distal end of the tooth row.
  • FIG. 2 shows a further advantageous embodiment of the frame without frame portion 2 which usually would be positioned at the rear of the row of teeth.
  • free carrying webs 6 are provided at frame portion 1, which runs in front of the row of the teeth, in order to receive the material which takes the bite impression.
  • strengthening portions 6a are provided at the free ends of webs 6 which engage the material like a barbed hook.
  • the dentist just breaks off the webs which are made of rather brittle material. The same is true if the dentist uses the frame without second portion 2, but free carrying webs 6 can be broken off from frame portion 1 at the places where the patient has still his natural teeth.
  • FIG. 3 a variation of the frame is shown in an enlarged sectional view taken along line A-B of FIG. 2. The difference is that the webs as shown in FIG. 3 are freely movable in the frame and the webs 6 are only retained at one portion of the frame. Webs 6 are provided with a T-section 6b at the point where they engage frame portion 1. A strengthening portion 6a is provided in the same manner as described with respect to FIG. 2.
  • a frame means curved so as to be substantially parallel to a row of teeth, for disposal in front of the row of teeth for taking bite impressions;
  • a plurality of elongated bars detachably coupled to and slidably moveable in said frame means, and radially extending therefrom, having a spherical portion affixed to the free ends thereof for supporting and securing bite impression material to the device.
  • said retaining elements are provided with a T-shaped end opposite the end to which said spherical element is affixed, and wherein said frame is provided with a vertically disposed slot extending within the periphery thereof for slidably receiving said T-shaped end and thereby permitting said retaining elements to be slidably positioned along the periphery of said frame means.
  • a device for taking bite impressions for making partial teeth prosthesis, extensions of prosthesis, crowns and bridges and the like, comprising:
  • a first frame means curved so as to be substantially parallel to a row of teeth, for disposal in front of the row of teeth for taking bite impressions;
  • first and second frame means curved so as to be substantially parallel to said first frame means, for disposal at the distal end of the row of teeth, said first and second frame means being arranged parallel to and in one plane with respect to each other;
  • a device for taking bite impressions for making partial teeth prosthesis, extension of prosthesis, crowns and bridges, and the like, comprising;
  • a first frame means curved so as to be substantially parallel to a row of teeth for disposal in front of the row of teeth for taking bite impressions
