ANATOMICAL FACTORS
INFLUENCING FORCEPS MOVEMENT
ROOT PATTERN OF UPPER TOOTH
1 → Straight conical root & circular cross section.
2 → Straight root which tapers to a curved apex with oval
cross section
3 → Long root, triangular in cross section and may have
apical curvature
4 → It has 2 tapered BP roots (easily fracture) Õ Two thin
and divergent root and conical neck.
5 → Has one root
ANATOMICAL FACTORS
INFLUENCING FORCEPS MOVEMENT
ROOT PATTERN OF UPPER TOOTH
6 → Have 3 divergent roots, 1 palatal and 2 thin buccal
roots. It is firmly embedded in the alveolar bone Õ difficult
in extraction due to the presence of the base of the malar
bone on its roots.
7 → Have 3 divergent roots, 1 palatal and 2 thin buccal
roots. It is firmly embedded in the alveolar bone
8 → The roots varied in shape and number, but frequently
have conical roots.
ANATOMICAL FACTORS
INFLUENCING FORCEPS MOVEMENT
ROOT PATTERN OF LOWER TOOTH
1, 2, 3 → Their roots are long and very thin.
4 → Straight single root
5 → It has conical root, rounded cross section.
6 → Mesial and distal roots.
7 → Mesial and distal roots.
8 → Root pattern is variable
COMPARATIVE THICKNESS OF
ALVEOLAR BONE ON THE BUCCAL
AND LINGUAL (PALATAL) SIDES:
MAXILLARY ALVEOLAR BONE:
•Buccal side is thin with little trabeculation, while palatal
side is thicker with more trabeculation.
•When using B-L movement, stress should be placed on
buccal movement since buccal bone will be easier to
expand.
•Maxillary teeth are delivered to the buccal side.
COMPARATIVE THICKNESS OF
ALVEOLAR BONE ON THE BUCCAL
AND LINGUAL (PALATAL) SIDES:
MANDIBULAR ALVEOLAR BONE:
•Anterior buccal bone is usually thinner thanlingual bone,
stress should he placed on buccal movement.
•In mandibular second and third molars, the buccal bone is
thicker (due to presence of external oblique ridge) than
lingual bone, stress is should be placed on lingual
movement.
PROCEDURE FOR CLOSED
EXTRACTION (GENERAL PRINCIPLES)
1. Adequate access and visualization.
2. Select the correct forceps.
3. Correct grasp of the forceps.

4. TOOTH GRIP
•Apical (initial) movement: force theblades of the forceps
under the gingival tissues down the periodontal membrane of
the tooth, on the buccal and lingual aspects till the blades
grip the root at or below the cemento-enamel junction.
•Rolf of parallelism: the blades should be aligned parallel to
the long axis of the tooth to distribute evenly the forces
applied to the root.

5. TOOTH MANIPULATION (EXTRACTION
MOVEMENT):
A. APICAL GRIP MOVEMENT: (WEDGING)
•Deep grip at C.E.J. or root surface extending to crestal
bone.
•Parallel to long axis of the tooth.
•Firm Grip to avoid sliding of the forceps over the tooth →
facture.
TECHNIQUES OF FORCEPS

5. TOOTH MANIPULATION
(EXTRACTION MOVEMENT):
A. APICAL GRIP MOVEMENT:
(WEDGING)
Aim:
•Wedging action.
•Dilatation of the bony socket at the
crest.
•Cutting period. ligament
attachment.
•Put the fulcrum in an upward
position to prevent root fracture.
TECHNIQUES OF FORCEPS
EXTRACTION (CLOSED EXTRACTION)
B. OUTWARD MOVEMENT:
•It's buccal or labial movement.
•Aim: Expansion of bony socket buccally at crest and
lingually at the apex.
TECHNIQUES OF FORCEPS
EXTRACTION (CLOSED EXTRACTION)
C. INWARD MOVEMENT:
•It's lingual or palatal movement
•Aim: Expansion of bony socket lingually at crest and
bucally at the apex.
•In all max teeth + all mand teeth (except 7 and 8) we begin
with outward movement as buccal cortical plate less than
lingual plate in thickness.
•In 7 & 8 we begin with ling. Movement As buccal Cortex is
enforced by external oblique ridge.
TECHNIQUES OF FORCEPS
EXTRACTION (CLOSED EXTRACTION)
D. ROTATION MOVEMENT:
The second movement in the following situation:
1 & 5 and 8 with conical roots.
Supernumerary tooth e.g. mesiodense when alveolar
bone is very thin.
Chronically infected, periodontal disease with bone
resorption.
•The fourth movement after tooth is loosened in the
socket to cut periodontal ligament attachment.
•Rotation movement is not done in children.
TECHNIQUES OF FORCEPS
EXTRACTION (CLOSED EXTRACTION)
E. FINAL MOVEMENT (TRACTION):
•Useful for delivering the tooth.
•This traction movement should be directed occluso-
buccaly except in case of lower third molar which is
occluso-lingualy to avoid the check.
PROBLEMS OF THE
BEGINNERS
1. Loose grip
2. Inadequate pressure
3. Insufficient time
4. Premature traction
ROLE OF THE ASSISTANT
1. Soft tissue reflection.
2. Suction.
3. Protection.
4. Support the mandible.
5. Psychological support for the patient.
THE PURPOSES OF
EXTRACTION MOVEMENTS
1. Cutting the tooth attachment.
2. Separating the tooth from the walls of the
socket.
3. Dilatation of the bony walls of the socket (taking
advantage of the elasticity of the living bone).
4. This will minimize the resistance around the
tooth.
5. Removal of the tooth from the socket.
FACTORS COMPLICATING
TEETH EXTRACTION
1. Restricted area (by lips and cheek).
2. Tongue movements.
3. mandibular movements (TMJ).
4. Tooth may be aspirated through the pharynx or larynx →
bronchi → lung leading to suffocation and lung abscess.
5. Proximity to vital structures e.g. Max. sinus, inferior
alveolar nerve.
6. Oral cavity is filled with saliva that contains M.0 that may
cause infection.
EXTRACTION OF DECIDUOUS
TEETH
FACTORS COMPLICATING EXTRACTION:
1.Limited access.
2.Root resorption → easy to fracture.
3.Resorbed root → irregular surface.
4.Fractured root → sharp shiny margin.
5.Tooth buds of premolars may be engaged by the roots of
deciduous molars.
EXTRACTION OF DECIDUOUS
TEETH
• We use the same technique but by pediatric forceps.
• Extraction technique: Use pediatric forceps.
• Avoid rotation movement → Fracture root & Injury to
successors.
• Avoid curettage injury to successors.
SEQUENCE OF EXTRACTION
• Chief complaint.
• Posterior before anterior teeth for better vision.
• Maxillary teeth before mandibular teeth:
 To Avoid fragment coming from maxillary teeth to
mandibular teeth.
 Because infiltration anesthesia has shorter duration than
nerve block.
 Maxillary teeth are easier in extraction.
• 6 and 3 are the last teeth to be extracted to have the
advantages of proper plate expansion of the adjacent
teeth.
POST EXTRACTION CARE
IMMEDIATE POST-EXTRACTION CARE:
•Examination of the socket for any tooth fragment, broken
filling or pieces of calculi.
•Squeeze the socket to decrease the socket orifice to:
•Allow proper organization of the blood clot in the socket to
prevent postoperative pain.
•Prevent saliva to enter the socket.
•Promotes rapid healing.
•To prevent bony undercuts.
•Clean the patient's lips and face from any blood spots.
•Dismiss the patients after examining the socket for
abnormal.
POST EXTRACTION CARE
POSTOPERATIVE INSTRUCTIONS: ON A
WRITTEN SLIP.
•Advise the patient to keep biting, pressure on the gauze for
about one hour.
•No mouth washes for at least 12 hours after extraction.
•Avoid any hot food or drinks for the rest of the day to prevent
bleeding.
•Avoid smoking.
•Do chewing away from the extraction site.
POST EXTRACTION CARE
POSTOPERATIVE INSTRUCTIONS: ON A
WRITTEN SLIP.
•Avoid brushing the teeth near the extraction site for one day.
•Use warm salt water as a mouth wash, it is started 24 hours
after the extraction.
•Avoid milk and milk product in the day of extraction as the
milk is consider a media for bacterial proliferation.
•Analgesics, for pain relief.
•Antibiotics describe only in case of preoperative infection.

APICAL GRIP MOVEMENT: (WEDGING) •Deep grip at C.E.J. or root surface extending to crestal bone. •Parallel to long axis of the tooth. •Firm Grip to avoid sliding of the forceps over the tooth → facture.

    TECHNIQUES OF FORCEPS EXTRACTION(CLOSED EXTRACTION) 5. TOOTH MANIPULATION (EXTRACTION MOVEMENT): A. APICAL GRIP MOVEMENT: (WEDGING) Aim: •Wedging action. •Dilatation of the bony socket at the crest. •Cutting period. ligament attachment. •Put the fulcrum in an upward position to prevent root fracture.
  • 63.
    TECHNIQUES OF FORCEPS EXTRACTION(CLOSED EXTRACTION) B. OUTWARD MOVEMENT: •It's buccal or labial movement. •Aim: Expansion of bony socket buccally at crest and lingually at the apex.
  • 64.
    TECHNIQUES OF FORCEPS EXTRACTION(CLOSED EXTRACTION) C. INWARD MOVEMENT: •It's lingual or palatal movement •Aim: Expansion of bony socket lingually at crest and bucally at the apex. •In all max teeth + all mand teeth (except 7 and 8) we begin with outward movement as buccal cortical plate less than lingual plate in thickness. •In 7 & 8 we begin with ling. Movement As buccal Cortex is enforced by external oblique ridge.

    TECHNIQUES OF FORCEPS EXTRACTION(CLOSED EXTRACTION) D. ROTATION MOVEMENT: The second movement in the following situation: 1 & 5 and 8 with conical roots. Supernumerary tooth e.g. mesiodense when alveolar bone is very thin. Chronically infected, periodontal disease with bone resorption. •The fourth movement after tooth is loosened in the socket to cut periodontal ligament attachment. •Rotation movement is not done in children.
  • 66.
    TECHNIQUES OF FORCEPS EXTRACTION(CLOSED EXTRACTION) E. FINAL MOVEMENT (TRACTION): •Useful for delivering the tooth. •This traction movement should be directed occluso- buccaly except in case of lower third molar which is occluso-lingualy to avoid the check.

    PROBLEMS OF THE BEGINNERS 1.Loose grip 2. Inadequate pressure 3. Insufficient time 4. Premature traction
  • 68.
    ROLE OF THEASSISTANT 1. Soft tissue reflection. 2. Suction. 3. Protection. 4. Support the mandible. 5. Psychological support for the patient.
  • 69.
    THE PURPOSES OF EXTRACTIONMOVEMENTS 1. Cutting the tooth attachment. 2. Separating the tooth from the walls of the socket. 3. Dilatation of the bony walls of the socket (taking advantage of the elasticity of the living bone). 4. This will minimize the resistance around the tooth. 5. Removal of the tooth from the socket.
  • 70.
    FACTORS COMPLICATING TEETH EXTRACTION 1.Restricted area (by lips and cheek). 2. Tongue movements. 3. mandibular movements (TMJ). 4. Tooth may be aspirated through the pharynx or larynx → bronchi → lung leading to suffocation and lung abscess. 5. Proximity to vital structures e.g. Max. sinus, inferior alveolar nerve. 6. Oral cavity is filled with saliva that contains M.0 that may cause infection.
  • 71.
    EXTRACTION OF DECIDUOUS TEETH FACTORSCOMPLICATING EXTRACTION: 1.Limited access. 2.Root resorption → easy to fracture. 3.Resorbed root → irregular surface. 4.Fractured root → sharp shiny margin. 5.Tooth buds of premolars may be engaged by the roots of deciduous molars.
  • 72.
    EXTRACTION OF DECIDUOUS TEETH •We use the same technique but by pediatric forceps. • Extraction technique: Use pediatric forceps. • Avoid rotation movement → Fracture root & Injury to successors. • Avoid curettage injury to successors.
  • 73.
    SEQUENCE OF EXTRACTION •Chief complaint. • Posterior before anterior teeth for better vision. • Maxillary teeth before mandibular teeth:  To Avoid fragment coming from maxillary teeth to mandibular teeth.  Because infiltration anesthesia has shorter duration than nerve block.  Maxillary teeth are easier in extraction. • 6 and 3 are the last teeth to be extracted to have the advantages of proper plate expansion of the adjacent teeth.
  • 74.
    POST EXTRACTION CARE IMMEDIATEPOST-EXTRACTION CARE: •Examination of the socket for any tooth fragment, broken filling or pieces of calculi. •Squeeze the socket to decrease the socket orifice to: •Allow proper organization of the blood clot in the socket to prevent postoperative pain. •Prevent saliva to enter the socket. •Promotes rapid healing. •To prevent bony undercuts. •Clean the patient's lips and face from any blood spots. •Dismiss the patients after examining the socket for abnormal.
  • 75.
    POST EXTRACTION CARE POSTOPERATIVEINSTRUCTIONS: ON A WRITTEN SLIP. •Advise the patient to keep biting, pressure on the gauze for about one hour. •No mouth washes for at least 12 hours after extraction. •Avoid any hot food or drinks for the rest of the day to prevent bleeding. •Avoid smoking. •Do chewing away from the extraction site.
  • 76.
    POST EXTRACTION CARE POSTOPERATIVEINSTRUCTIONS: ON A WRITTEN SLIP. •Avoid brushing the teeth near the extraction site for one day. •Use warm salt water as a mouth wash, it is started 24 hours after the extraction. •Avoid milk and milk product in the day of extraction as the milk is consider a media for bacterial proliferation. •Analgesics, for pain relief. •Antibiotics describe only in case of preoperative infection.
