TWIN BLOCK EFFECTS

  • The bite blocks acts as a guiding mechanism causing the mandible to be displaced downward and forward.
  • The unfavorable cuspal contacts of a distal occlusion are replaced by favorable proprioceptive contacts on the inclined planes of twin-blocks to correct the malocclusion & to free the mandible from its locked distal functional position.
    • Occlusal inclined planes
    • Initially the angulation between the blocks were made at 90 degrees
    • since it was difficult to hold the mandible forward at this angle, the angulation was changed to a 45 degree one
    • the angulation was changed to 70 degrees to the occlusal plane to apply a more horizontal force encouraging a more forward mandibular growth.
