Q

What forceps are used for extraction of mandibular permanent teeth?

A

-Lower permanent molar forceps

20
Q

Where does the point of the beat fit with lower permanent molar forceps?

A

-Furcation of molars

21
Q

How do you prevent transmission of infection to patients in an extraction?

A
  • Gloves
  • Surgical mask
  • Eyewear
  • Side shields with eyewear
  • Sterile disposable towel drape
  • Proper oral hygiene
22
Q

What are the requirements for ideal extraction?

A
  • Satisfactory access and visualization of field of surgery
  • Un-obstructed pathway for the removal of the tooth
  • The use of controlled force to luxate and remove the tooth
23
Q

What are the mechanical principles for tooth extractions?

A
  • Expansion of the bony socket
  • Use of fulcrum or lever
  • Insertion of wedge or wedges
  • Wheel and axel
24
Q

How do you expand the bony socket?

A

-By use of the wedge shaped beaks of the forceps

25
Q

How should the forceps be seated?

A

-With strong apical pressure

26
Q

Why do you use strong apical pressure?

A

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

27
Q

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

A

-Excess movement of tooth apex

28
Q

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

A

-Fracture of root apex

29
Q

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

A

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

30
Q

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

A

-Buccal bone at apical area

31
Q

Initial rotational forces are useful for removal of what teeth?

A

-Conical roots such as maxillary central

32
Q

Tractional forces are useful for what?

A

-Final removal of tooth from socket

33
Q

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

A

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

34
Q

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

A

-Disto buccal

35
Q

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

A

-Outward and occlusal

36
Q

What are the three movements of extractions?

A
  • Outward
  • Inward
  • Rotatory movements
37
Q

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

A

True

38
Q

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

A

-External oblique ridge

39
Q

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

A

-Primary rotatory movement

40
Q

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

A
  • Upper central incisor

- Lower second premolars

41
Q

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

A

-Bucco-lingual

42
Q

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

A

-Spiral fracture

43
Q

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

A

-Carious side with the first movement made towards the caries

44
Q

Do not use a straight elevator when next to what type of tooth?

A
  • Carious

- Crown

45
Q

The wedge principle is useful for the extraction of teeth in several different ways, what are they?

A
  • By using the beaks of the extraction forceps as a wedge

- When a straight elevator is used to luxate a tooth from its socket

46
Q

When one root of a multiple rooted tooth is left in the alveolar process what do you use?

A

-Pennant-shaped elevator (wheel and axel)

47
Q

T/F The opposite hand plays and important role in supporting and stabilizing the lower jaw when mandibular teeth are being extracted

A

True
