Custom fitted intra-oral appliances
View Patent ↗Methods and apparatus for transmitting vibrations via an electronic and/or actuator assembly through a custom-fitted dental appliance are disclosed herein. The customized fitting is done by the user. The assembly may be attached, adhered, or otherwise embedded intra-orally on a tooth or oral tissue. The electronic and actuator assembly may receive incoming sounds either directly or through a receiver to process and amplify the signals and transmit the processed sounds via a vibrating actuator element coupled to a tooth or other bone structure, such as the maxillary, mandibular, or palatine bone structure.
1. An intraoral apparatus, comprising:
an actuatable transducer configured to transmit sound through bone conduction;
a user-fabricated custom fit base having a first and a second housing configured to be securely pressed against sides of one or more teeth on opposite surfaces of the one or more teeth or oral tissue, respectively, wherein the actuatable transducer is disposed within or upon the first housing and is configured to transmit vibrations to the one or more teeth; and
an arm coupled to the first and second housings.
2. The apparatus of claim 1 wherein the user fabricated custom fit base comprises a thermoplastic co-polymer.
3. The apparatus of claim 1 , wherein the user fabricated custom fit base comprises ethylene vinyl acetate (EVA) or polyethylene material.
4. The apparatus of claim 1 , wherein the user fabricated custom fit base comprises a hardenable material.
5. The apparatus of claim 4 , further comprising a relief valve in fluid communication with the custom fit base to discharge excess hardenable material.
6. The apparatus of claim 1 , wherein the custom fit base comprises one or more cavities in one or more tooth contacting regions.
7. The apparatus of claim 6 , wherein the one or more cavities are filled with PVS or an impression material at first use to conform to the patient's dentition.
8. The apparatus of claim 1 , wherein the arm comprises a loop.
9. The apparatus of claim 1 , wherein the arm is corrugated, jagged, round, or rectangular.
10. The apparatus of claim 1 , wherein the arm contacts the one or more teeth to deliver sound energy.
11. The apparatus of claim 1 , wherein the custom fit base slidably cooperates with the arm to fit different tooth sizes.
12. The apparatus of claim 1 , wherein the first housing comprises a moveable dental contact point which allows a user to adjust a contact position with the one or more teeth.
13. The apparatus of claim 1 further comprising an electronic assembly disposed within or upon the first housing.
14. The apparatus of claim 13 wherein the electronic assembly further comprises a receiver in wireless communication with an externally located transmitter assembly.
15. The apparatus of claim 13 wherein the electronic assembly is encapsulated within the first or second housing.
16. The apparatus of claim 13 wherein the electronic assembly further comprises a power supply in electrical communication with the transducer.
17. The apparatus of claim 13 wherein the electronic assembly further comprises a processor in electrical communication with the transducer.
18. The apparatus of claim 13 wherein the electronic assembly further comprises a microphone for receiving auditory signals and which is in electrical communication with the processor.
19. A method of transmitting, vibrations, comprising:
heating a base material;
biting into the base material to form a custom-fit base wherein the custom-fit base having a first and a second housing is configured to be securely pressed against sides of one or more teeth on opposite surfaces of the one or more teeth or oral tissue, respectively, the custom-fit base further having an arm coupled to the first and second housings;
positioning an actuatable transducer on or along the first housing of the base;
securing the custom-fit base and the actuatable transducer on the one or more teeth or oral tissue such that the transducer and the one or more teeth are in vibrational communication; and
actuating the transducer such that an audio signal is vibrationally conducted through the one or more teeth or oral tissue.
