• Side shields with eyewear
• Sterile disposable towel drape
• Proper oral hygiene

Question 22

What are the requirements for ideal extraction?

Answer 22

• Satisfactory access and visualization of field of surgery
• Un-obstructed pathway for the removal of the tooth

Question 23

What are the mechanical principles for tooth extractions?

Answer 23

• Expansion of the bony socket

Question 24

How do you expand the bony socket?

Answer 24

Question 25

How should the forceps be seated?

Answer 25

-With strong apical pressure

Question 26

Why do you use strong apical pressure?

Answer 26

-To expand crestal bones and to displace center of rotation as apically as possible

Question 27

IF the center of rotation is not far enough apically and too far occlusally what does the result in?

Answer 27

-Excess movement of tooth apex

Question 28

What does excess motion of root apex caused by high center of rotation result in?

Answer 28

-Fracture of root apex

Question 29

What does buccal or labial pressure applied to a tooth do?

Answer 29

-Expand the buccal cortical plate toward the crestal bone with some lingual expansion at the apical end of the root

Question 30

Lingual or palatal pressure will expand the lingual cortical plate at the crestal area and slightly expand what?

Answer 30

-Buccal bone at apical area

Question 31

Initial rotational forces are useful for removal of what teeth?

Answer 31

-Conical roots such as maxillary central

Question 32

Tractional forces are useful for what?

Answer 32

-Final removal of tooth from socket

Question 33

What teeth do you not want to roll to the buccal?

Answer 33

-Mandibular 2nd and 3rd molars you want to roll these to the lingual

Question 34

What direction should the final removal of a maxillary 3rd molar be?

Answer 34

-Disto buccal

Question 35

What should the removal of all teeth be, besides the maxillary 3rd and mandibular 2nd and 3rd molars?

Answer 35

-Outward and occlusal

Question 36

What are the three movements of extractions?

Answer 36

- Outward - Inward - Rotatory movements

Question 37

T/F THe movement should be steady and with a reasonable force

Answer 37

True

Question 38

What is the buccal plate of bone reinforced by on the 2nd and 3rd molars?

Answer 38

-External oblique ridge

Question 39

What is the initial movement used in upper central incisor and lower second premolars?

Answer 39

-Primary rotatory movement

Question 40

What teeth do you use a primary rotatory movement as the initial movement in?

Answer 40

- Upper central incisor | - Lower second premolars

Question 41

If resistance is felt in primary rotation what type of movement should be started?

Answer 41

-Bucco-lingual

Question 42

If rotatory movement is continued when you feel resistance what might happen?

Answer 42

-Spiral fracture

Question 43

The extraction forceps blade should be applied to what side first?
