Various methods and apparatus for processing audio signals are disclosed herein. The assembly may be attached, adhered, or otherwise embedded into or upon a removable oral appliance to form a hearing aid assembly. Such an oral appliance may be a custom-made device which can enhance and/or optimize received audio signals for vibrational conduction to the user. Received audio signals may be processed to cancel acoustic echo such that undesired sounds received by one or more intra-buccal and/or extra-buccal microphones are eliminated or mitigated. Additionally, a multiband actuation system may be used where two or more transducers each deliver sounds within certain frequencies. Also, the assembly may also utilize the sensation of directionality via the conducted vibrations to emulate directional perception of audio signals received by the user. Another feature may include the ability to vibrationally conduct ancillary audio signals to the user along with primary audio signals.

Embodiments of the present invention provide devices (tags with sensors), systems, and methods to determine states (such as, but not limited to, complex impedance) of materials-of-interest, such as tissue-of-interest, implants, and construction members, to name a few, in a non-invasive and contactless way; and using comparatively safe and/or low energy electromagnetic radiation, such as radio waves. Negligible-sized wireless-tags with sensors are implanted in such materials-of-interest. Using wireless communication and imaging technology, the states of the materials-of-interest may be monitored; which may allow non-invasive and contactless detection of problems such as cracking, bending, excessive pressure, improper temperature, and/or the like. Additionally, initially unknown locations of the implanted negligible-sized wireless-tags with sensors may be readily determined upon a given scanning (reading) session; and thus mapped to provide an effective image of the material-of-interest.

A gastrointestinal administration device comprising an elongated tube or track, an anchor and a channel, which allows the proximal end of the tube or track to be wholly secured inside the mouth from where it passes down the lateral oropharynx to the desired site in the gastrointestinal tract. This system may be used to administer nutrients, fluids, medications, nutraceuticals, dietary supplements and/or non-nutrient gastrointestinal stimulants or other therapies directly to a desired site in the gastrointestinal tract in humans and animals for a variety of purposes including novel applications such as weight and glucose control, local administration of medication and storage of a deposit of a therapeutic agent. It may also be used for monitoring of processes inside the gastrointestinal tract.

A dental implant evaluation unit is disclosed and described. The dental implant evaluation includes a body portion having threads that mimic the general thread pattern of an actual dental implant, without attempting to copy any of the osseointegrative features of the actual implant. A threaded collar is associated with the body portion, and, in certain embodiments, a safety flange is screwed to the threaded collar. The safety flange prevents the dental implant evaluation unit from infiltrating the sinus of a patient when testing the fit of a maxillary implant. The dental implant evaluation unit can be used by a dentist to evaluate the proper size and fit for an actual dental implant by installing the dental implant evaluation unit, and imaging the same, prior to installing the actual dental implant.

Dental implants including radiopaque markers provided therein or thereon. The implant may also include customizable length characteristics. For example, a kit may include implants with different diameters (e.g., 3 diameters), where all of the implants are of a single (e.g., long) length. The appropriate diameter implant may be selected from the kit by the practitioner, and the long length implant may be cut (e.g., with a dental drill) to the appropriate length needed. The implants include radiopaque markers on or within the implant. For example, three series of markers may be provided on different faces of the implant, so that the three series of markers serve as reference points when scanning, allowing triangulation of the exact position of the implant in relation to the surrounding hard and soft oral tissues.

Prosthetic dental device comprising a first axial-symmetric intraosseus component, or implant (11) and a second component, or abutment (12) configured to be connected on one side to the first intraosseus component (11) and to support, on another side, a prosthetic dental component.

An apparatus includes a dental prosthetic, a metallic insert, and a plastic cap member. The insert is configured to be bonded in an interior of the dental prosthetic. The insert defines a passageway. The of the insert is configured to receive a screw. The cap member is configured to be interposed between the insert and the interior of the dental prosthetic.

The present invention relates to a detachable implant-coupling prosthesis, and more specifically to a detachable implant-coupling prosthesis which enables an implant and a coupling prosthesis to be easily coupled to each other and can be easily coupled to and separated from each other during revision and re-placement. According to the present invention, via the unique distinguishing structure capable of achieving easy coupling without using a screw fastening method screw fastening method, loosening and fracture do not occur, and an aesthetic effect and durability can be prevented from being degraded because it is not necessary to form a hole in a tooth. Furthermore, the coupling prosthesis can be easily separated without destructing a tooth when a problem occurs after the placement of an implant, and thus effects arise in that the inconvenience of a patient can be mitigated and cost can be reduced during the treatment of inflammation or periodontitis.

A system of components for comfortably, easily, and precisely installing a complete dental implant, including the crown, and a method of installing the complete dental implant, including the crown, is disclosed. The components comprise a dental implant, an impression transfer, a lab analog, and an abutment to which the crown is to be permanently installed.
