i dit not make it :p

1. Instruments in Oral Surgery
Jan 18, 2008

2. Hemostats vs. Needle Holders
 Hemostats
 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
Can easily pinch or cut lips and cheek tissue

18. Molt Curette 2/4
 #2 end is smaller to enucleate a
cavity, cyst, granulomas, etc.

19. Minnesota Retractor
 Retract mucoperiosteal flap
 Protect mucosa during cutting
 Rest on bone ONLY

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
