Hemostats vs. Needle Holders

Hemostats


Used for placing and removing surgical
blades
Needle holders
Have gold loops
 Used specifically for pushing needles and
suturing

Hemostats vs. Needle Holders
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

Chisels

Monobevel

Remove bone
Bibevel

Split Teeth
Elevators
301-smallest
 34
 46S-Largest

301 Elevator
Lever action
 Displacement
 Smaller root tips

34 Elevator
Lever action
 Displacement
 Most teeth and larger root tips

46S Elevator
Lever action
 Displacement
 Most teeth and larger root tips

Curved Cryers

Max. Impacted 3rds Molars ONLY

Like a spoon, roll them out
Cryer Elevator
Wheel and axle
 Adjacent empty socket
 Mandibular first molars
 Needs sharp tip i.e. no purchase point

East/West
Wheel and axle
 Adjacent empty socket
 Mandibular first molars
 Needs sharp tip i.e. no purchase point

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

Potts Elevators
Max. Impacted 3rds Molars ONLY
 Wheel and axle
 Miller elevator with “T” handle
 Can deliver more force

Bone File
Used for superficial smoothing
 Only used with a pull-stroke
 Otherwise you burnish the bone

Rongeur #4A
Side cutting and end-cutting rongeurs
Used by general dentists
Cut bone by means of pinching
Rongeur #5
Large-bladed, side cutting rongeurs
“Bone forceps”- cuts bone rather than pinching
bone
Can easily pinch or cut lips and cheek tissue
Molt Curette 2/4

#2 end is smaller to enucleate a
cavity, cyst, granulomas, etc.
Minnesota Retractor
Retract mucoperiosteal flap
 Protect mucosa during cutting
 Rest on bone ONLY

Periosteal Elevator
Start with the pointed edge
 Reflect the flap with the broad end

Clover Leaf

Sweetheart retractor, “Weider”
Austin Retractor

Place down on bone, retracts cheek
and protects
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

Forceps
Designed to attached to the
anatomical crown of teeth
 150 max. universal
 151 mand. universal
 150S/151S- pedo max. and mand.

Forceps
Maxillary forceps have a gradual Sshaped curve
 Mandibular forceps have 90 degree
bend

150/151 Forceps
Anterior Forceps
Maxillary- #1 or #99 Anterior Cuspid
to Cuspid- specific!
 Mandibular- 74 (Ash) can also use on
the premolars

#1, #99 Forceps
74N Forceps
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

88R and 88L
