Abstract

An apparatus, a system and a method are provided for providing a dental diagnosis and/or a dental appliance to a user by examining a portion of a mouth of the user. To this end, the apparatus, system and method may evaluate images whether digital, still, video, digital x-ray or the like, of the portion of the mouth to determine if a medical condition may be cured and/or corrected by a dental appliance stored within a machine and capable of being dispensed from the machine. In addition, the system may provide a wafer or tray which the user may position in his mouth to make an impression. The wafer or tray, or an image of the wafer or tray, may then be sent to an individual and/or a central processing unit. Also, a user may position a film within his mouth and transmit the film or an image of the film to an individual and/or a central processing unit.

Claims

1. A method for diagnosing an orthodontic condition of a plurality of teeth of a mouth of a patient wherein the plurality of teeth have sizes, the method comprising the steps of:

providing a wafer which fits inside the mouth wherein the wafer has a labial side and a lingual side wherein the labial side is located in a position opposite to the lingual side and further wherein the wafer is made from a material capable of being bitten creating a deformation of the wafer wherein the deformation corresponds to one tooth of the plurality of teeth and further wherein the one tooth has a size wherein the wafer retains the deformation following removal from the mouth;

generating an image of the deformation;

transmitting the image of the deformation to a remote location without sending the wafer to the remote location; and

determining the sizes of the plurality of teeth based on the deformation wherein a central processing unit programmed with dental standards that are statistics regarding standard sizes of teeth determines the sizes of the plurality of teeth using the size of the one tooth indicated to the central processing unit by the image of the deformation and further wherein the plurality of teeth that are not the one tooth are not used to determine the sizes of the plurality of teeth wherein the central processing unit is located at the remote location.

2. The method of claim 1 wherein the central processing unit determines the sizes of the plurality of teeth using the size of the one tooth without using any other measurements associated with the patient.

3. The method of claim 1 wherein the image is a depth sensitive photograph.

4. The method of claim 1 further comprising the step of:

determining if the one tooth is reliable for determination of the sizes of the plurality of teeth wherein the central processing unit determines if the one tooth is reliable.

5. The method of claim 1 further comprising the step of:

providing a dental appliance that has a size that corresponds to the sizes of the plurality of teeth.

6. The method of claim 1 wherein the material is a pressure-sensitive film.

7. The method of claim 1 wherein the material is a photo-sensitive film.

8. A method for diagnosing an orthodontic condition of upper teeth and lower teeth of a mouth of a patient wherein one of the upper teeth is an upper front incisor and one of the lower teeth is a lower front incisor wherein the upper front incisor has a mesio-distal width and the lower front incisor has a mesio-distal width, the method comprising the steps of:

providing a wafer which fits inside the mouth of the patient wherein the wafer is made from a material that may be deformed to create a deformation and further wherein the patient bites biting into the wafer with the mouth creating the deformation of the wafer wherein the deformation corresponds to the upper front incisor and the lower front incisor of the mouth wherein the wafer retains the deformation following removal from the mouth wherein the mesio-distal width of the upper front incisor and the mesio-distal width of the lower front incisor are determined from the deformation;

determining a size of the upper teeth and a size of the lower teeth based on the mesio-distal width of the upper front incisor, the mesio-distal width of the lower front incisor and dental standards that are statistics regarding standard sizes of teeth without using any other measurements associated with the patient wherein the upper teeth that are not the upper front incisor are not used to determine the size of the upper teeth and further wherein the lower teeth that are not the lower front incisor are not used to determine the size of the lower teeth; and

diagnosing the orthodontic condition of the mouth from the deformation on the wafer wherein a size of an orthodontic appliance is based on the size of the upper teeth and the size of the lower teeth.

9. The method of claim 8 further comprising the step of:

providing an orthodontic appliance based on a diagnosis of the orthodontic condition of the mouth.

10. The method of claim 8 further comprising the step of:

transmitting an image of the deformation to a remote location without sending the wafer to the remote location.

11. The method of claim 8 wherein a central processing unit determines the size of the upper teeth and the size of the lower teeth based on the mesio-distal width of the upper front incisor, the mesio-distal width of the lower front incisor and the medical standards.

12. The method of claim 8 further comprising the step of:

generating an image of the deformation wherein the size of the upper teeth and the size of the lower teeth are determined using the image.

13. The method of claim 8 further comprising the step of:

sending the wafer to the patient via direct mail.

14. The method of claim 8 further comprising the step of:

constructing the wafer from a photo-sensitive film.

15. The method of claim 8 further comprising the step of:

constructing the wafer is constructed from a pressure-sensitive film.

16. A method for diagnosing an orthodontic condition of upper teeth and lower teeth of a mouth of a patient, the method comprising the steps of:

providing a wafer which fits inside the mouth wherein the patient bites into the wafer with the mouth to create deformations in the wafer wherein the deformations correspond to the upper teeth and the lower teeth of the mouth and further wherein a first deformation corresponds to a single tooth;

creating an image of the wafer;

transmitting the image of the wafer to a location remote from where the deformations were created;

diagnosing the orthodontic condition of the upper teeth and the lower teeth at the location remote from where the deformations were created wherein the diagnosis is based on only the first deformation and dental standards that are statistics regarding standard sizes of teeth wherein the image of the wafer is transferred to the location remote from where the deformation was created prior to diagnosing the orthodontic condition;

determining a size of a dental appliance for the mouth based on the first deformation and the dental standards; and

providing the dental appliance based on the diagnosis.

17. The method of claim 16 further comprising the step of:

constructing the dental appliance based on the first deformation and the dental standards.

18. The method of claim 16 further comprising the step of:

selecting the dental appliance from a plurality of pre-formed dental appliances wherein the plurality of pre-formed dental appliances are manufactured before diagnosis of the mouth.

19. The method of claim 16 wherein the first deformation corresponds to an incisor.

20. The method of claim 16 further comprising the step of:

taking a depth-sensitive photograph of the wafer prior to diagnosis wherein the depth-sensitive photograph is the image transmitted to the location remote from where the deformations were created.
