*<unk>  is a non-surgical bone conduction prosthetic device that transmits sound via the teeth. It is an alternative to surgical bone conduction prosthetic devices, which require surgical implantation into the skull to conduct sound.<unk>  uses the tooth instead of the implanted component and eliminates the need for surgery. It is therefore typically lower in complications and in cost than the prevalent surgical treatments.<unk>  has two principal components: a behind-the-ear (BTE) microphone unit that is worn on the impaired ear and a removable, custom-made in-the-mouth (ITM) device worn on the upper, left or right back teeth. Both components have rechargeable batteries and a charger is included with the<unk> . The BTE microphone captures and processes sound, and wirelessly transmits the sound signals to the ITM device. The ITM receives these signals and converts them into sound vibrations. These subtle sound vibrations travel via the teeth, through bones in the skull, to the functioning inner ear or cochlea, bypassing problems in the outer or middle ear entirely. Although the vibrations are strong enough to be picked up by the cochlea, they are so subtle as to not be felt by the wearer. In the United States, the device has FDA clearance to treat patients with single-sided deafness (SSD) or conductive<unk>  loss (CHL).<unk>  also has CE mark approval for SSD, CHL, and mixed<unk>  loss (MHL).<unk>  was developed and marketed by Sonitus Medical, Inc. The company filed for bankruptcy on Thursday, January 15, 2015, as a result of the US Centers for Medicare & Medicaid Services' decision not to cover the device.
