the shank, but the blade is straight, rather than triangular, and has convex and a flat
surface.
The flat surface is working surface and the transverse serration on it for better contact
with the root stump.
When viewed the instrument look like a hockey stick.
Extraction Forceps
Extraction forceps are designed to deliver teeth from the socket.
Each forcep has an handle, a joint and a beak.
www.indiandentalacademy.com
31. All the forceps have cross hatching on the handle to allow a firm grip and have
serrations on the inner side of the beaks to allow better grip on the tooth.
The forceps beaks are applied along the long axis of the tooth, below Cementoenamel junction of the tooth.
A firm grip is established prior to giving any forcep movement.
Maxillary Extraction forceps
The handle and the beaks are at 180 deg. To each other, i.e. in a straight line.
Maxillary Anterior Forceps
They have identical beaks that are closed, straight, flat and broad.
They are used to extract the maxillary incisors and canines.
Maxillary Premolar Forceps
They have identical beaks that are concave on the side of facing the oprator.
The beaks are broad and open.
They are used for extraction of premolars.
The curvature of the blade is to access the premolars placed posteriorly in the arch.
Maxillary Molars (Right and Left)
The beaks of these forceps are not identical. One beak is rounded and other one is
www.indiandentalacademy.com
33. Pointed.
The pointed beak engages the groove between the buccal roots and the rounded one
engages the palatal surface below cemento-enamel junction.
The beaks also have curvature to the side facing operator.
When viewed, if the pointed beaks to the left of the operator it is right sided forcep and
vice versa.
Maxillary Cowhorn Forceps
These forceps have unidentical beaks, one of which has pointed tip and other one has
bifid pointed tip.
The single pointed tip engages the furcation between the two buccal roots and the
other bifid pointed tip engages the palatal root.
It is paired forceps. The beaks are curves towards operator. While viewing the
concave surface of the beaks, the bifid beaks will be on the right for the maxillary right
side forceps abs vice versa.
They are used for maxillary teeth, where there is extensive destruction of the crown,
but roots are not seprate.
Maxillary anterior root forceps
They have identical, straight, slender and closed beaks.
www.indiandentalacademy.com
34. They are used primarily for extraction of stumps of the maxillary anterior teeth.
Maxillary posterior root forceps
They are similar to the anterior root forceps, but like the premolar forceps, they have
curvature towards the operator for access posteriorly.
They are used for removing of single molar root pieces and premolar root stumps.
Bayonet Forceps
They have identical, pointed, angulated and closed beaks. The length of the beaks
vary from long to short.
According to the thickness of the beak they can be classified into thick beaks and thin
beak bayonet forceps. The thick beak forceps is used to remove maxillary posterior
root stumps that are not separate, while the thin beak forceps are used to remove
single roots.
Mandibular Forceps
Mandibular Anterior Forceps
The mandibular anterior forceps have identical broad, short, closed beaks. The joints
is a rivet joint unlike most forceps have box joint.

They have identical, broad, open beaks that are longer than the beaks of anterior
forceps.
They are used for extracting mandibular molar teeth.
Mandibular Cowhorn Forceps
It has identical, open, beaks that resemble the horn of the cow. The beaks are round
and taper to the point.
The forceps grips the tooth at the furcation between the mesial and distal roots.
When pressure is applied and the beaks are closed, the tooth is luxated or literally
squeezed out of the socket, using buccal and lingual plates as the fulcrum.
They are used to remove grossly carious mandibular molars with extensive
destruction of the crown.
Mandibular root forceps
These forceps have identical, slender beaks that are closed. The beaks are longer
than that of the premolar forceps to enable the forceps to take a deep grip on the root
