2. Hemostats vs. Needle Holders
Used for placing and removing surgical blades
Needle holders
Have gold loops
Used specifically for pushing needles and suturing

3. Hemostats vs. Needle Holders

4. Full Thickness Flaps Mucosa, Submucosa and Periosteum
Submucosa contains nerves, arteries, veins and lymphatics
We raise full thickness flaps in O.S.
Less swelling
Less bleeding
Less pain

5. Chisels
Monobevel-
Remove bone
Bibevel
Split Teeth

6. Elevators
301-smallest 34
46S-Largest

7. 301 Elevator
Lever action
Displacement
Smaller root tips

8. 34 Elevator
Lever action
Displacement
Most teeth and larger root tips

9. 46S Elevator
Lever action
Displacement
Most teeth and larger root tips

10. Curved Cryers Max. Impacted 3rds Molars ONLY
Like a spoon, roll them out

11. Cryer Elevator Wheel and axle Adjacent empty socket
Mandibular first molars
Needs sharp tip i.e. no purchase point

12. East/West Wheel and axle Adjacent empty socket Mandibular first molars
Needs sharp tip i.e. no purchase point

13. Miller Elevator Wheel and axle Impacted maxillary thirds
NOT erupted maxillary thirds
Place at MB of third molar below HOC and roll to the distal

14. Potts Elevators Max. Impacted 3rds Molars ONLY Wheel and axle
Miller elevator with “T” handle
Can deliver more force

15. Bone File Used for superficial smoothing Only used with a pull-stroke
Otherwise you burnish the bone

16. Rongeur #4A Side cutting and end-cutting rongeurs
Used by general dentists
Cut bone by means of pinching

17. Rongeur #5 Large-bladed, side cutting rongeurs
“Bone forceps”- cuts bone rather than pinching bone

20. Periosteal Elevator Start with the pointed edge
Reflect the flap with the broad end

21. Clover Leaf
Sweetheart retractor, “Weider”

22. Austin Retractor
Place down on bone, retracts cheek and protects

23. Bone Thickness
The thinnest bone is on the lingual of the third molar region
Most common place to find bone spicules
If bone spicule is attached to bone, reflect flap
If bone spicule is separated, pull it out with tweezers, adson forceps

24. Forceps Designed to attached to the anatomical crown of teeth
150 max. universal
151 mand. universal
150S/151S- pedo max. and mand.

25. Forceps Maxillary forceps have a gradual S-shaped curve
Mandibular forceps have 90 degree bend

26. 150/151 Forceps

27. Anterior Forceps
Maxillary- #1 or #99 Anterior Cuspid to Cuspid- specific!
Mandibular- 74 (Ash) can also use on the premolars

28. #1, #99 Forceps

29. 74N Forceps

30. Broken Crowns
Due to IRM, Deep decay, Temp. crowns, RCT “brittle teeth”
88R, 88L- maxillary 1st and 2nd molars
Need furcation to engage forceps
1 prong between buccal roots
2 prongs cradle the palatal root
Expands the buccal plate, can break roots and crush tissue

31. 88R and 88L
