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 )
