Orthodontic assistant FINAL EXAM
1. The following orthodontic appliance is best used to correct a patient with a
-3mm overjet in a 8 year old boy: Reverse pull headgear (facemask)
2. The following orthodontic appliance is best used to achieve absolute anchorage
so there is no reciprocal movement?: TADS
3. This type of elastic provides the least force: 5/16 4.5oz
4. Class II elastics are places by connecting the elastics to which teeth?: Upper
3's to Lower 6's
5. Class II elastics are called "class II elastics" because if compliant, it can
shift a :: Class II occlusion to a class I occlusion
6. Class 2 and vertical
(Delta Elastics):
7. Kobeyashi Tie: Helps to achieve a better occlusion
8. These types of wires exhibit super elasticity, the ability to bend and return
to its original shape: NiTi
9. This type of wire will provide the lightest and most gradual force: NiTi
10. This type of wire will exhibit the most amount of friction: TMA
, 11. This wire is NOT likely to be the first wire to be placed immediately after
placing brackets on a patient: Rectangular stainless steel
12. This type of wire is most likely used to close extraction spaces: Rectangular
stainless steel
13. In brackets that have torque prescription, this type of wire is most likely to
express the torque prescribed: 17x25 Stainless Steel
14. This type of wire is most formable: Stainless Steel
15. This type of wire is temperature sensitive where if it's chilled, it is able to
bend and before formable, but when heated it has memory and goes back to
its original form: Copper NiTi
16. This type of wire has the most strength and stiffness: Stainless Steel
17. This is NOT an alloy: Gold
18. Cut arch wire with this instrument:
19. The following instrument is used for?: Cut stainless steel ligature ties
20. Bird beak plier: To make bends in arch wire
