Diabrux - Device and fully automated evaluation software for quantitative diagnosis of sleep bruxism

Ref.-Nr. 2235

Keywords: sleep bruxism, teeth grinding, diagnosis, bite film, fully automated evaluation software, monitoring of bruxism activity

Outside the scientific setting of a sleep laboratory, diagnosis of sleep bruxism mainly relies on examination for clinical evidence – e.g. indicated by the tips of the teeth appearing flat – and on standardized questionnaires. There is a lack of a user-friendly and validated device for standardized, quantitative diagnosis is available so far. As a result, bruxers are often diagnosed at late stage, when severe consequences of teeth grinding, such as abraded teeth, facial pain, headache and damage to the temporomandibular joints are apparent. As simple management of buxism such as mouthguards/splints is available to prevent damage, early diagnosis, treatment and follow-up are clearly needed.

Diabrux is worn by the patient like a night splint. The device is based on a hard plate, which is covered by five specifically linked layers with different colours and defined abrasion properties. A fully automated evaluation software is provided for standardized, objective, quantitative analysis.


  • Validated in clinical study
  • Fully automated evaluation software
  • Enables personalized planning prior to cost-intensive treatment
  • High patient compliance
  • White surface facilitates use by day
  • Straight-forward manufacturing based on established processes
  • Low production costs

Kommerzielle Anwendung

Diabrux not only allows early diagnosis of bruxism, but also facilitates monitoring of bruxism activity. Thus, personalized therapy planning is possible and cost-intensive treatments can be scheduled more accurately.
The device is easy to apply. Patient compliance is high as irritation by the thin device does not occur. Production of the device is based on established processes and production costs underline the economic feasibility.

Aktueller Stand

In contrast to currently available devices for diagnosis of sleep bruxism, Diabrux has been successfully validated in a clinical study. On behalf of Heinrich Heine University of Duesseldorf PROvendis offers access to rights for commercial use. In case of interest we will be pleased to provide further information.
