In Class III malocclusions there are beside the characteristic shape and form of the dental arches present also functional problems of incorrect tongue posture on the mouth floor. Three-dimensional diagnostics will be presented to assess facial, jaw’s morphology and tongue posture in children with Class III malocclusion before, during and after orthopedic treatment. Contemporary diagnostics enables noninvasive, valid and objective morphological and functional diagnostics in the assessment of early orthopedic treatment in Class III dentofacial deformities.

Learning Objectives:

  • Identify that tongue posture in majority of children with Class III malocclusion is on the mouth floor.
  • Recognize that early treatment in Class III involves rapid palatal expansion, face mask.
  • Evaluate the characteristic morphology of the upper jaw in Class III patients is lower values of palatal volume and smaller values of gingival surface area.
