Q

Step 1 loosen soft tissue:
What instrument?
Why is it done? (2)

A

Periosteal elevator (curette)

  1. Seating forceps more apically
  2. assures anestesia

Q

Step 2 Luxation with elevator
Where is it positioned?
Technique? (2)

A

PERPENDICULAR btwn teeth

  1. STRONG, slow pressure
  2. inferior blade rests on and uses fulcrum of BONE
    - With superior blade on extracted tooth.

Q

What a mandibular sling grasp?

A

Index and first finger are used same a pinch grasp and other fingers hold mandible extraorally.

Q

Maxillary Canines Forceps 1 (or 3, clinically)

A
  1. 150

2. and 3: 1 and 99 also

22
Q

Maxillary Canines

-what is your action if LABIAL plate fractures?

A

-Separate bone from root with: periosteal elevator

23
Q

***Bone still attached to periosteum will be vital, otherwise it will die and should be removed

A

ANSWER ONLY

24
Q

Maxillary 1st Premolar root morph (3)

A
  • Usually has 2 roots
  • Apex is thin
  • Apex has distal curvature
25
Q

Maxillary 1st Premolar Forceps (2)

A
  1. 150

2. 150A

26
Q

Maxillary 1st Premolar Extraction steps/technique (3)

A
  • Elevator luxation as much as possible
  • Remember: palatal root easily fractures
  • More dependent on tractional force to deliver tooth
27
Q

Maxillary 2st Premolar root morphology (3)

A
  • RARELY bifurcated
  • Thick
  • Blunt apex
28
Q

Maxillary 1st and 2nd molars root morphology (2)

A
  • 3 roots (palatal largest)

- Buccal roots are curved and thin

29
Q

Maxillary 1st and 2nd molars: sinus proximity concerns

A

Worry about breaking into sinus

-consider surgical extraction

30
Q

Maxillary 1st and 2nd molars Forceps

  • Intact (2)
  • Gross Decay (4)
  • Extensive bone loss or conical(2)
A

intact ( 53 R and L)

Gross (88 R and L AND 89,90)

Extensive bone loss (150 and 210)

31
Q

Maxillary 3rd molar root morph (2)

A

conical/fused and variable

32
Q

Maxillary 3rd molar Forcep

A

210-S

33
Q

Mandibular anteriors root morph (4)

A

*The roots are ovoid and longest B-L —> Ex: 0

straight

  • thin incisors
  • thick canines
34
Q

Mandibular anteriors Forceps (2)

A
  1. 151

2. 74 Ashe

35
Q

Mandibular anteriors Removal concern

A

When removing multiple, do not rotate because the ovoid shape will break interdental alveolar bone

36
Q

Mandibular Premolars Root morph (2)

A
  1. long, slender

2. Rarely bifurcated

37
Q

Mandibular Premolars forceps (3)

A
  1. 151
  2. 151 A
  3. 74 Ashe
38
Q

Mandibular Premolars what movement is: “it’s super effective” for extraction

A

*Rotational

39
Q

Mandibular 1st and 2nd molars root morph

A

Bifurcated

  • 1st more divergent
  • 2nd more often fused-conical
40
Q

Mandibular 1st molar alveolar bone

A

It is essentially equal width/strength as the buccal

41
Q

Mandibular 1st and 2nd molars

  • intact
  • gross
  • fused roots
A

intact - 17
gross - 23
fused roots - 222

42
Q
  • Mandibular 2nd molars technique for 17

- only unique direction of removal

A

-Remove occlusal lingually* (not buccally)

43
Q

Mandibular 1st and 2nd molars technique for 23

A

Appose the beaks while resting on cortical plates as fulcrums!

44
Q

Mandibular 3rd molars Root morph

A

All effed up

-fused conical or bifurcated

45
Q

Mandibular 3rd molars forcep

A

222

46
Q

*erupted MAND 3rds are still difficult even if erupted, IF they are in occlusion

A

ANSWER

47
Q

If you can’t get alveolar expansion, what is the concern and reason for using a surgical route instead?

A

Massive fracture of alveolar bone (or roots too…)

48
Q

What are the only things that indicate debridement walls of alveolus? (5)

A
  1. Calculus
  2. Amalgam
  3. Tooth fragment
  4. Loose bone*****
  5. Granulation tissue
49
Q

What two components of the socket aid in proper healing?

A

PDL fragments and (bleeding) bony walls

50
Q

What should you palpate for in a bony socket?

-how to fix?

A

Sharp edges of bone

-use bone file
