Hemostats vs. Needle Holders • Hemostats • Used for placing and removing surgical blades • Needle holders • Have gold loops • Used specifically for pushing needles and suturing
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 S-shaped curve • Mandibular forceps have 90 degree bend
Anterior Forceps • Maxillary- #1 or #99 Anterior Cuspid to Cuspid- specific! • Mandibular- 74 (Ash) can also use on the premolars
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
