Vibration Motors Used to Combat Bruxism

BruXane wearable mouthpiecebruXane GmbH is a German-based company working to develop a product that prevents excessive grinding of teeth. We take particular interest in their application because they use our vibration motors!

The technical name of the activity is ‘bruxism’, which can occur whilst sleeping or awake and can cause a range of problems including tooth wear, a sore jaw, and headaches. Many ‘bruxers’ are unaware that they are ‘bruxing’, which can continue throughout the entire night if they are sleeping.

bruXane® is a solution that forces users to change their behaviour by notifying them when they start to brux, through a vibration motor moulded into a wearable mouthpiece worn overnight. Initial results are very promising!

The left axis is the longest length of brux (data in the bar chart) and the right axis the average lengths of brux (data in the line graph). We can clearly see which date the user started to wear bruXane®.

What’s most interesting to us, is the application overcomes several design and manufacturing challenges. First, the product is obviously extremely limited in space. Coin motors are a great solution because they have an extremely low profile – you can use this link to select only our vibration motors and see the available coin motors.

In addition, the mouthpiece is moulded to fit each individual user. Overmolding normal ERM motors impede the eccentric mass and stop it from working. We have a range of encapsulated vibration motors that work for larger applications, but again the coin motors’ masses are protected with the metal casing. If you’re interested in testing, we’ve previously conducted experiments into over-moulding some of our vibration motors.
