New mouthguard for detection and treatment of bruxism

30.01.2008
Researchers from the Universidad Politécnica de Madrid are working on the development of a mouthguard prototype for the evaluation and diagnosis of bruxism and its characteristic gnashing of teeth.

Bruxism is a parafunctional activity caused by the excessive activation of a reflex chewing action during sleep, with the effect of grinding teeth or clenching the jaw. It causes premature wear of the teeth along with a noise that can be loud enough to disturb the sleep of some one sharing the bedroom.

The constant and prolonged tension on the jaw can cause headaches, earaches, damage to muscles, teeth, and circumjacent tissues, or structures like the mandibular articulations. All of these symptoms are encompassed under the umbrella term Temporomandibular joint disorder (TMJD). Bruxism, affecting around 25% to 30% of the population, and being more frequent in children, is a subject of great interest at the Universidad Politécnica de Madrid where a research team is currently working with real patients on the design, development, manufacture, fine-tuning and testing of prototype mouth guards filled with sensors to detect and treat bruxism.

The research team is formed of participating engineering specialists from the Escuela Técnica Superior de Ingenieros Industriales, the Escuela Universitaria de Ingeniería Técnica Industrial, and the Universidad Politécnica de Madrid, all working in collaboration with the company “Ibex Estética Dental”.

Wireless transmission to alert the patient
The mouth guard device works by transmitting a wireless signal to portable electronic devices capable of collecting frequency, duration and intensity data of the events for further qualitative and quantitative diagnosing of the patient, as well as alerting them of their behaviour when required, so they are aware and able to stop the prejudicial bruxism.
Therapeutic use
Once the project is finalised, the mouthguard will be used mainly therapeutically to eliminate bruxism along with the symptoms it causes, including dental deterioration, muscle pains and headaches. The researchers intend to use the data collated not only for diagnostic purposes, but also as evaluation aids for a patient’s response to treatment and their evolution.

Im Focus: Scientists channel graphene to understand filtration and ion transport into cells

Tiny pores at a cell's entryway act as miniature bouncers, letting in some electrically charged atoms--ions--but blocking others. Operating as exquisitely sensitive filters, these "ion channels" play a critical role in biological functions such as muscle contraction and the firing of brain cells.

To rapidly transport the right ions through the cell membrane, the tiny channels rely on a complex interplay between the ions and surrounding molecules,...

Im Focus: Towards data storage at the single molecule level

The miniaturization of the current technology of storage media is hindered by fundamental limits of quantum mechanics. A new approach consists in using so-called spin-crossover molecules as the smallest possible storage unit. Similar to normal hard drives, these special molecules can save information via their magnetic state. A research team from Kiel University has now managed to successfully place a new class of spin-crossover molecules onto a surface and to improve the molecule’s storage capacity. The storage density of conventional hard drives could therefore theoretically be increased by more than one hundred fold. The study has been published in the scientific journal Nano Letters.

Over the past few years, the building blocks of storage media have gotten ever smaller. But further miniaturization of the current technology is hindered by...
