An imbalance between the mouth muscles (lips, chewing muscles, tongue and tongue muscles) also influences the shape of the jaws and the position of the teeth and molars. An open bite is easy to measure with a ruler. For a large overjet in combination with an open bite, the SOB meter might be useful. To get an indication whether we are dealing with a skeletal or myogenic open bite, a measurer for angle of mandible can be used.

    Measurer for angle of mandible
