Abstract: A method and apparatus for recording and measuring in-situ skull vibration includes a receiving means, a transducer mounted into or unto the receiving means and capable of transducing mechanical vibration within the dental bone conduction pathway into electrical signals, and extra-oral recordation hardware and software capable of receiving and processing the electrical signals from the transducer.

Abstract: An apparatus for imparting low amplitude vibrations to at least one tooth in a human head having a cochlea to facilitate hearing via a dental bone conduction pathway includes an extraoral transmitter, a band at least substantially surrounding and adhesively secured to at least one tooth, and a receiver assembly. The transmitter is configured to detect ambient sounds, and to generate and wirelessly transmit audio signals corresponding to the detected ambient sounds. The receiver assembly is removably coupleable to the band and configured to receive the audio signals from the transmitter, and to transduce the audio signals into vibrations that are conducted to the cochlea via the dental bone conduction pathway.

Abstract: A method and system of aligning antennas of an intra-oral and extra-oral electronic wireless device is provided. Three-dimensional anatomical data of at least a portion of an oral cavity of a subject and at least a portion of an external ear of the subject is recorded. A spatial relationship between a landmark in the oral cavity and a landmark in the external ear is determined. A first antenna is modeled based upon the anatomical data of the oral cavity, and a second antenna is modeled based upon the anatomical data of the external ear. The antennas are configured and oriented relative to each other for optimal signal transmission based upon the recorded anatomical data of the oral cavity and ear.

Abstract: The present invention relates generally to the design and optimal placement of transmitting and receiving directional antennas, a priori, as used in intra-oral to extra-oral (or visa versa) wireless electronic systems regardless of the type and purpose of the data transmitted between the antennas (intra-oral and extra-oral). Systems related to the invention transmit data via electromagnetic radio waves or through an inductive loop coupling such as in stimulating the human hearing nerve (inner ear) via dental bone conduction pathway when operating in “receive mode”. “Send mode” systems related to the invention transmit non-acoustic information or voice data from inside the mouth to a receiver located outside the mouth.

Abstract: A method and apparatus for measuring and recording skull vibration in situ comprising a receiving means, a dental material capable of filling any gaps between the receiving means and the at least one tooth, the material capable of transmitting mechanical vibration within the dental bone conduction pathway to the receiving means; a transducer mounted into or unto the receiving means said transducer capable of transducing mechanical vibration within the dental bone conduction pathway into electrical signals; an extra-orally recordation hardware and software capable of receiving and processing said electrical signals from said transducer.

Abstract: An audiodontic device includes a transducer implanted in a dental post hole drilled into a root canal of a tooth, preferably a maxillary molar. The transducer imparts vibratory signals to the tooth in response to applied audio signals. A precision attachment device includes a female connector embedded in a dental crown of electrically non-conductive material covering a built-up core and through which electrical leads, or the like, extend to transducer terminals located at the core periphery. Audio signals are delivered to the transducer from a radio receiver or induction loop embedded in an insulative housing contoured for buccal or lingual vestibular mounting adjacent the tooth, or disposed in a denture or retainer. In either case, a male connector for the precision attachment conducts the received audio signal from the receiver to the tooth.
