Question 3

lateral luxation

Answer 3

extraction in severe displacement in labial direction case
14/7 soft diet

Question 4

extrusive luxation

treatment based on degree of displacement
mobility

intrusive luxation

Answer 5

dislocation of a tooth in an axial direction into the alveolar bone
radiograph to assess degree of intrusion
large force is required to intrude teeth

Question 6

Orthodontic repositioning

Answer 6

a RA with self supporting spring or elastic module to apply vertical extrusive force through a bracket bonded on the labial or incisal surface
