Forceps & elevatorsPrepared by : Mohammed Nameer

Upper straight forceps• Straight• Heavy blades• No space between the blades• Used for extraction of Upper centrals and canines both right and left with The same forceps

• Straight• Narrow blades• No space between the blades• Used for extractionOf upper lateral and upper anterior Retained roots both right and left with the same forceps

Upper premolars forceps

• Has 2 bends

• The 2 blades are mirror image to each other

• The 2 blades has no projections and rounded end

• Used to extract both right and left upper premolars with The same forceps

Upper molars forceps

• Has 2 bends• Palatal blade is round and the buccal blade has a projection to fit the roots bifurcation on the buccal side of the molar• There are 2 forceps one for the

rightMolars and one for the left

Bayonet forcepsof the upper 3rd molar• For extraction ofUpper third molar (right and left with the same forceps)

• The blades are parallelTo the long axis of The handle

• There is a space between the blades

Bayonet forceps of the upper retained roots

• Used for the extraction of The upper posterior retained roots

• The blades are parallel to the long Axis of the handle

• There is no space between the blades

The forceps of the lower teeth

Forceps of the lower anterior (cental,lateral & canine)

• Fine blades

• The blades are perpendicular on the long axis of the handle

• No space between the blades

• Used for extraction of the Lower central and lateral incisors both right & left Teeth with the same forceps

• Heavy blades

• The blades are perpendicular on the long axis of the handle

• No space between the blades

• Used for extraction of Lower canine both right & left Teeth with the same forceps

Premolars forceps

• Heavy blades

• There is a space between the blades

• The blades ends are rounded and has no projection

• Used to extract the lower premolars , both right and left teeth with the same forceps

Lower molars forceps• Heavy blades

• There is a space between the blades

• Both of The blades ends have a projection

• The same forceps is used to extract both right and left lower molars •

Elevators

Straight elevator • Handle , shank and blade are straight

• The working end is blind and round

• There are sizes

Coupland’s chisel elevators• Like straight elevator

• The working end is straight and sharp

• Used for chiseling the bone to create point of aplication or to split of teeth

• There are sizes 1 , 2 & 3

Apexo elevators

• Blade is long with sharp margins

• There is 2 angled and 1 straight

• Used for removing of apical fragments of root deeply present in the socket of the lower jaw (especilly molars )

Cryer’s elevators • Sharp, pointed and triangular shape blade

• There are mesial and distal elevators

• Used for removing of retained roots of lower molars And for elevation for impacted teeth after surgical exposure

Of the bifurcation of the tooth

Winter’s elevators (Winter’s T_Bar)cross-bar handle elevator

• the blade is like that of Cryer’s elevator

• The shank is in right angle to the handle

• It’s very powerful and great force generated(sufficient to fractre the mandible) !!!

War-wick James elevators • It is like Cryer’s elevators but with light duty

• There are 2 angled (mesial & distal) and 1 straight

• The blade is rounded and the handle is flattened

• Used to extract retained roots, deciduous teeth, lower anterior extraction and whereThere is less resistance are (e.g. upper 3rd molar extraction )
