Exodontia
Kristine C. Sumaoy, RN, MAN, DMD

2. Topics:
•Instrumentation for Basic Oral Surgery
•Principles of Routine Exodontia
•Principles of More Complex Exodontia
•Principles of Management of Impacted Teeth
•Postextraction Patient Management
•Medical and Legal Considerations

3. Learning Objectives
•Learn principles of exodontia as well as the instrumentation
and techniques;
•Know the basic instrumentation and the fundamental
applications of instruments to their surgical purposes;
•Learn the basic parts of dental instruments and how to use it;
•Learn how to manage patient who are undergoing extraction
surgery;

4. Instrumentation for Basic Oral Surgery
Incising Tissue
•SCALPEL: primary instrument for making incisions
-composed of a handle and a sharp blade
•No. 3 blade handle: most commonly used handle for oral surgery
•No. 15 blade: most frequently used scalpel blade for intraoral surgery
•Blade No. 11: sharp-pointed blade that is used primarily for making small
stab incisions
Blade No. 12: used for mucogingival procedure in which incisions are made on
posterior aspects of teeth or in the maxillary tuberosity area.

7. REMINDER:
Scalpel blades are
designed for single-
patient use only!!

8. MOLT No. 9 : Elevating the Mucoperiosteum

9. Retractors
•Helps protect soft tissue from sharp cutting instruments
•Help provides good access and vision during surgery
Minnesota Retractors
Henahan Retractor
Austin Retractors
Seldin Retractor

10. Grasping Soft Tissue
Adson Tissue Forceps
Allis Forceps
:most commonly used forceps for
grasping soft tissue

11. Controlling Hemorrhage
Hemostat (straight or curved)
Hemostat
•has long, delicate beaks that are used to
grasps tissues and a locking handle.
•use to control bleeding when direct
pressure to surgical site is deemed
insufficient.
•can be used during suturing and/or
cauterization.
•useful in removal of debris, granulation
tissues, pieces of calculus etc.

12. Removing Bone
RONGEURS:most commonly used removing bone in dentoaveolar surgery
•this instrument has sharp blades that are squeezed together by the handles,
cutting or pinching through bone

18. Suture Material
Sizes of suture relates to its
diameter and is designated
by a series of zeros.
•3-0
•4-0
•5-0
•7-0
•Sutures can be resorbable
or non-resorbable

19. Suture Material
•most commonly used sutures for oral
cavity
•Has appropriate strength and its silk
polyfilamentnature makes it easy to
tie and well tolerated by the patient’s
tissue.
•The color makes it easy to see for
suture removal

20. Dental Elevators
Components:
•Handle
•Shank
•blade
3 basic types:
•the straight type : most commonly used elevator
•the triangle or pennant-shaped type: second most common
•the pick type

21. Straight Elevators
•most commonly used elevator to
luxate teeth
•blade of the straight elevator is
concave on its working side
•concave surface on one side of the
elevator is placed toward the tooth to
be elevated
•Straight elevators vary in size
depending on the width of the blade

22. Triangular-type Elevators
•second most commonly used type of
elevator
•provided in pairs: a left and a right
•most useful in removing retained root
fragment where the adjacent socket is
empty.
•When used, the tip is inserted in the
purchased point and the elevator is
then turned in a wheel-and-axle
rotation
•comes in a variety of types and
angulations: Cryer elevator is the
most common type
Cryer Elevator

23. Crane Pick
Root-tip Pick
•This type of elevator is used to
remove roots
•This instrument is used as a lever to
elevate a broken root from the tooth
socket
•May or may not need to create a
purchase point to remove root
fragment from the socket
•Another type of pick elevator is the
root-tip pick or the apex elevator
•SHOULD NOT be used as a wheel &
axle or lever type of elevator such as
the Cryer elevator or the Crane pick
Pick-type Elevators

24. Periotomes
•instruments used to extract teeth while preserving
the anatomy of the tooth’s socket
•tip of periotome blade is inserted into the
periodontal ligament space and advanced (2-3mm)
using apical pressure along the long axis of the tooth
and reinserted again into an adjacent accessible site
•process is repeated until sufficient severance of PDL
has been accomplished then tooth is removed by
using a dental elevator, extraction forceps, or both,
taking care to avoid excessive expansion or fracture
of bone.

25. Extraction Forceps
•extraction forceps are instruments used for
removing the tooth from alveolar bone
•Ideally, forceps are used to lift elevator-luxated
teeth from their sockets rather than to pull
teeth from their sockets
Forceps Components
•Handles
•Hinge
•beak

26. Handle of Forceps
•adequate in size for comfortable use and
easy to deliver sufficient pressure and
leverage to remove the required tooth
•have a serrated surface to allow a positive
grip and to prevent slippage
•handles of the forceps are held differently
depending on the position of the tooth to
be removed
•Maxillary forceps are held with the palm to
the side or underneath the forceps so that
the beak is directed in a superior direction
•mandibular forceps are held with the palm
on top of the forceps so that the beak is
pointed down toward teeth

27. Beaks of Forceps
•source of the greatest variation among forceps
•designed to adapt to the tooth root near the junction of the
crown and root
•Note: beaks of the forceps are designed to be adapted to the
root structure of the tooth and not to the crown of the tooth
•the more closely the beaks of the forceps adapt to the tooth
roots, the more efficient is the extraction and the lower is the
chance for undesired outcomes

29. Maxillary Forceps
•removal of maxillary teeth
requires the use of instruments
designed for single-rooted teeth
and for teeth with three roots
•single-rooted teeth: maxillary
incisors, canine teeth, and
premolar teeth*
•trifurcated roots: maxillary
molars

32. Mandibular Forceps
•Extraction of mandibular
teeth requires forceps that
can be used for single-rooted
teeth: incisors, canines, and
premolars as well as for two-
rooted teeth for the molars
