1

Goals of using forceps (2)

1. Expansion of bony socket
2. Tractional force (removal)

2

Six basic forcep moves

Apical
buccal
lingual
rotational
tractional
circular

3

Which forcep movement is first?

Apical (expand bony socket)

4

When pressing crown buccally, what direction does root apex move?

Lingually

5

Which movements are only good on conical roots?

Rotational
(figure of eight as well....)

6

Key points of arm and hand positioning (3)

Elbow in
Straight wrist
-Palm Down (mandibular)
-Palm up (Maxillary)

7

Sequence of the 5 steps for routine extraction

1. Loosen soft tissue attachment
2. Luxation (Elevator)
3. Adapt forceps
4. Luxate WITH forceps
5. Traction (final removal)

8

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

Periosteal elevator (curette)

1. Seating forceps more apically
2. assures anestesia

9

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

PERPENDICULAR btwn teeth

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

10

Step 3 adapt forceps
Which beak applied first?

LINGUAL!!!!!!!! (harder to see)

11

Step 4 luxation with forceps
Where is the lingual bone NOT thicker than buccal?

Mandibular molars (the more posterior the thinner lingual bone)

12

Step 5 Removal of tooth from socket
*Be gentle should come out easily
Which direction is this delicate force applied?

Buccally
-clinically: follow growth pattern where possible

13

What is a pinch-grasp?

It is with your left hand, feeling on the buccal and lingual surfaces of alveolar bone. on MAXILLA

14

Why do you use a pinch-grasp? (3)

1. Retract tissues
2. Stabilize patients head
3. Detect possible alveolar fractures

15

What a mandibular sling grasp?

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

16

What are two ways of protecting patient during a mand extraction?

1. Bite block (mouth prop)
2. Mandibular sling grasp

17

Maxillay incisor root morphology
-central
-Lateral (2)

Central- long conical

Lateral- SLENDER and distal curve

18

Maxillary incisor Forcep selection (3)

1. 150
2. 1
3. 99

19

Maxillary Canines (root morphology) (2)

Longest roots of all
ovoid: broader buccal-Lingually!

20

Maxillary Canines Alveolar bone*

The labial (facial/buccal) bone is quite thin and fractures easily!

21

Maxillary Canines Forceps 1 (or 3, clinically)

1. 150
(2. and 3: 1 and 99 also)

22

Maxillary Canines
-what is your action if LABIAL plate fractures?

-Separate bone from root with: periosteal elevator

23

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

ANSWER ONLY

24

Maxillary 1st Premolar root morph (3)

*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)
