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. The female connector includes a channel contoured to slidably receive the male connector to thereby firmly hold the receiver housing in place while maintaining the necessary electrical contact to pass the received audio signal to the transducer.
