Dental intrusion is an apical displacement of the tooth into the alveolar bone. This injury is accompanied by extensive damage to periodontal ligament , cementum , disruption of the neurovascular supply to the pulp, and communication or fracture of the alveolar socket.
Intrusion is a movement in the field of orthodontics where a tooth is moved partially into the bone. Intrusion is done in orthodontics to correct an anterior deep bite or in some cases intrusion of the over-erupted posterior teeth with no opposing tooth.

Correction of open bite in permanent dentition may involve extrusion of the anterior teeth or intrusion of the posterior teeth. This decision depends on the incisor show on smiling for a patient. If a patient has normal incisor show at rest smile, than molar intrusion may be done in these type of faces.
Dental avulsion is the complete displacement of a tooth from its socket in alveolar bone owing to trauma, such as can be caused by a fall, road traffic accident, assault, sports, or occupational injury.
If a tooth is avulsed, make sure it is a permanent tooth (primary teeth should not be replanted, and instead the injury site should be cleaned to allow the adult tooth to begin to erupt).
