2) Articulare
3) Condylion
4) Pterygomaxillary

Orthodontics Answer: 2

If the tooth has not erupted to the line of occlusion it is called
1) Supraversion
2) Torsiversion

1) Loss of anchorage
2) Severe opening of bite
3) Loss of retention
4) All of the above

1) Buccal canine retractor
2) Coffin spring
