Home / Orthodontics / Intrusion


  • Intrusion has always been a challenge to the orthodontist,while some¬† authors claim it is possible to achieve intrusion some others claim that it is impossible to achieve true intrusion. The biomechanical and histological basis of this tooth movement has been a difficult problem for evaluation and understanding.


  • Intrusion is defined as the apical movement of the geometric center of the root in respect to the occlusal plane or a plane based on the long axis of the tooth
  • Pseudointrusion¬† refers to the labial tipping of the incisor around the centroid
  • Relative intrusion, deep bite correction by the extrusion of the posterior teeth rather than the true intrusion of the anterior teeth
