Abstract

Methods and apparatus for transmitting vibrations via an electronic and/or transducer assembly through a dental implant are disclosed herein.
The assembly may be attached, adhered, or otherwise embedded into or upon the implant to form a hearing assembly. The electronic and transducer 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 transducer element coupled to a tooth or other bone structure, such as the maxillary, mandibular, or palatine bone structure.

Claims (25)

1. An apparatus for transmitting vibrations via bone or tissue to facilitate hearing in a patient, comprising:
an implant having an implant head and a threaded portion adapted to be positioned below a gum line; and a housing coupled to the implant head and in vibratory communication with the implant head, the housing having an actuatable transducer disposed within or upon the housing.
2. The apparatus of claim 1 wherein the housing is coupled the implant head through one of: an electro-magnetic coupling to the implant head, a mechanical coupling to the implant head, a chemical coupling to the implant head.
3. The apparatus of claim 1 further comprising an electronic assembly disposed within or upon the housing and which is in communication with the transducer.
4. The apparatus of claim 3 wherein the electronic assembly is encapsulated within the housing.
5. The apparatus of claim 3 wherein the electronic assembly further comprises a power supply in electrical communication with transducer.
6. The apparatus of claim 3 wherein the electronic assembly further comprises a processor in electrical communication with the transducer.
7. The apparatus of claim 6 wherein the electronic assembly further comprises a microphone for receiving auditory signals and which is in electrical communication with the processor.
8. The apparatus of claim 3 wherein the electronic assembly further comprises a receiver in wireless communication with an externally located transmitter assembly.
9. The apparatus of claim 1 wherein the actuatable transducer is in vibratory communication with the surface via an adhesive layer for maintaining the transducer in contact with the surface.
10. The apparatus of claim 2, wherein the housing comprises a ball adapted to be seated in an indentation above the implant head.
11. The apparatus of claim 2, wherein the implant head is charged with a first magnetic polarity and the housing is charged with an opposite magnetic polarity.
12. The apparatus of claim 11 further comprising at least one biasing element positioned adjacent to the transducer such that the biasing element maintains the transducer against the implant head via a biasing force.
13. The apparatus of claim 12 wherein the at least one biasing element comprises a spring.
14. The apparatus of claim 2 wherein the housing is inserted into the implant head.
15. The apparatus of claim 14, comprising a U-shaped clip to mount the housing to the implant head.
16. The apparatus of claim 2, wherein the housing is secured to the implant head using a screw.
17. The apparatus of claim 2 further comprising an interface layer between the transducer and the implant head through which vibratory communication is maintained.
18. The apparatus of claim 17 wherein the interface layer comprises a plastic or paste material.
19. A method of transmitting vibrations via one or more dental implants, comprising:
placing the one or more dental implants on a patient; and
20 positioning an actuatable transducer such that the implant and transducer remain in vibratory communication.

20. The method of claim 19 comprising magnetically securing the dental implant to the actuatable transducer.
21. The method of claim 19 comprising mechanically securing the dental implant to the actuatable transducer.
22. The method of claim 19 comprising chemically securing the dental implant to the actuatable transducer.
23. The method of claim 19 wherein the implant comprises an exposed head to receive a snap fit housing.
24. The method of claim 19 comprising using the one or more dental implants to treat tinnitus or stuttering.
25. The method of claim 19 comprising using the dental implant to treat stuttering by providing a frequency shift and a delayed auditory feedback.
