Artificial teeth are suitable as potential hearing aids because they can transmit vibrations effectively.
In a research paper titled “Bone Conduction Sensitivity for Dental Implants,” which was published earlier this month in the Journal of the American Acoustic Society, ovocephalus from Tongji University in Shanghai demonstrated how well implants sound. Describes a test to determine whether
Authors Fengxuan Ren, Yutong Li, Lidan Chen, Jiaqi Huang, and Jianxiang Tao explain how bone conduction through natural teeth is well known to produce auditory effects. However, little research has been done on sound transmission by artificial teeth.
So the researchers recruited 38 people who met the required criteria and sent them via a vibrating device placed on either a dental implant, a natural tooth, or the mastoid bone (located just behind the ear), and they heard the signal for what to do. The stimuli took the form of sounds with frequencies between 250 Hz and 4000 Hz at 30 dB and lower decibel levels when participants indicated that they heard sounds.
The result was a dental implant [bone conduction] It outperforms natural teeth and the mastoid at some frequencies.”
The results of this study also show that implants in the front teeth (anterior teeth) have a lower threshold for detecting vibrations than those in the back teeth (molars). “[A]Internal dental implants showed better results [bone conduction] We speculate that this is due to the difference in bone density between the anterior and posterior portions of the jaw.
The first orthopedic (BAHA) hearing aid was implanted in 1977 by Anders Tjellström at the University of Gothenburg. These devices are now in the form of products such as the Cochlear Baha System, Oticon Ponto, and Medtronics Alpha 2 MPO ePlus. Some do not require surgery (attached to a headband), while others require surgical implantation of metal screws or magnets that support the external sound processing unit, depending on the specific condition being treated. There is also
Both BAHA and cochlear implants are options for treating severe hearing impairment. BAHAs, whether surgical or non-surgical, rely on vibration to transmit sound waves to the inner ear and auditory nerve. Cochlear implants are almost always surgically placed and transmit sound directly to the auditory nerve via electrical impulses.
There have been several obstacles to the development of conductive hearing technology. For example, US federal regulations regarding Medicare reimbursement. About ten years ago, a company called Sonitus Medical raised $80 million to develop a non-invasive hearing system. I am hard of hearing. “
Three years later, the company declared bankruptcy after the Centers for Medicare and Medicaid Services (CMS) decided not to reimburse patients for their Soundbite devices (a dental-fit mouthpiece and microphone receiver). The federal agency that oversees Medicare has classified the device as a hearing aid, not a hearing aid, because it does not require surgery.
So perhaps vibrating dentures can survive the bureaucracy of the American healthcare system because they are implanted rather than worn out.
“Excellent dental implants [bone conduction] Characteristics, dental implants are available as a possibility [bone conduction] The researchers concluded that oral hearing aids could be a supplement. In this case, dental implant hearing aids offer unique advantages in real-world applications such as better concealment, better comfort, and improved sound quality. ®
