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.
-this helps stabilize mandible

Q

Maxillary Canines Alveolar bone*

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
Maxillary 1st Premolar Forceps (2)
1. 150 | 2. 150A
26
Maxillary 1st Premolar Extraction steps/technique (3)
- Elevator luxation as much as possible - Remember: palatal root easily fractures - More dependent on tractional force to deliver tooth
27
Maxillary 2st Premolar root morphology (3)
- RARELY bifurcated - Thick - Blunt apex
28
Maxillary 1st and 2nd molars root morphology (2)
- 3 roots (palatal largest) | - Buccal roots are curved and thin
29
Maxillary 1st and 2nd molars: sinus proximity concerns
Worry about breaking into sinus | -consider surgical extraction
30
Maxillary 1st and 2nd molars Forceps - Intact (2) - Gross Decay (4) - Extensive bone loss or conical(2)
intact ( 53 R and L) Gross (88 R and L AND 89,90) Extensive bone loss (150 and 210)
31
Maxillary 3rd molar root morph (2)
conical/fused and variable
32
Maxillary 3rd molar Forcep
210-S
33
Mandibular anteriors root morph (4)
*The roots are ovoid and longest B-L ---> Ex: 0 straight - thin incisors - thick canines
34
Mandibular anteriors Forceps (2)
1. 151 | 2. 74 Ashe
35
Mandibular anteriors Removal concern
When removing multiple, do not rotate because the ovoid shape will break interdental alveolar bone
36
Mandibular Premolars Root morph (2)
1. long, slender | 2. Rarely bifurcated
37
Mandibular Premolars forceps (3)
1. 151 2. 151 A 3. 74 Ashe
38
Mandibular Premolars what movement is: "it's super effective" for extraction
*Rotational
39
Mandibular 1st and 2nd molars root morph
Bifurcated - 1st more divergent - 2nd more often fused-conical
40
Mandibular 1st molar alveolar bone
It is essentially equal width/strength as the buccal
41
Mandibular 1st and 2nd molars - intact - gross - fused roots
intact - 17 gross - 23 fused roots - 222
42
* Mandibular 2nd molars technique for 17 | - only unique direction of removal
-Remove occlusal lingually* (not buccally)
43
Mandibular 1st and 2nd molars technique for 23
Appose the beaks while resting on cortical plates as fulcrums!
44
Mandibular 3rd molars Root morph
All effed up | -fused conical or bifurcated
45
Mandibular 3rd molars forcep
222
46
*erupted MAND 3rds are still difficult even if erupted, IF they are in occlusion
ANSWER
47
If you can't get alveolar expansion, what is the concern and reason for using a surgical route instead?
Massive fracture of alveolar bone (or roots too...)
48
What are the only things that indicate debridement walls of alveolus? (5)
1. Calculus 2. Amalgam 3. Tooth fragment 4. Loose bone***** 5. Granulation tissue
49
What two components of the socket aid in proper healing?
PDL fragments and (bleeding) bony walls
50
What should you palpate for in a bony socket? | -how to fix?
Sharp edges of bone | -use bone file
