2. Introduction
ī¯ It is a procedure that incorporates
principles of surgery, physics and
mechanics.
ī¯ Painless removal of the tooth or root
with minimal injury to the
surrounding soft tissue & bone
2
3. Cont.
ī¯ Removal of tooth does not require
large amount of force, but fine and
controlled forced in such a manner
that tooth is not pulled from bone but
lifted gently from alveolar process
3
4. Pain and Anxiety control
ī¯ Local anesthesia
īŽ Profound local anesthesia results in loss
of pain, temperature and touch but not
pressure.
īŽ When the tooth has pulpitis or
surrounding soft & hard tissues inflamed
or infected, periodontal injection is
given, that gives anesthesia for 15-
20min. If it fails intra osseous injection
can be given.

11
12. Sedation
ī¯ In case of mild anxiety- proper
explanation of procedure; assurance
that there will not be sharp pain,
expression of concern caring,
empathy will reduce anxiety.
ī¯ In moderate anxiety: Preoperative
oral diazepam provide rest at night
before surgery and relieve anxiety in
morning.
12
13. Cont.
ī¯ Sedation by inhalation of nitrous
oxide or IV sedation with diazepam
can be given in severe anxiety.
13
15. Indications for removal of teeth
ī¯ Severe caries: that can not be
restored.
ī¯ Pulpal necrosis: if endodontic Rx can
not be performed becoz Pt declines,
or root canal that is tortuous, calcified
or endodontic failure.
ī¯ Severe periodontal disease: excessive
bone loss and irreversible tooth
mobility.
15
16. Cont.
ī¯ Mal - opposed teeth; if they
traumatize the soft tissue or can not
be repositioned by orthodontic Rx
(Max. III M. in severe buccal version
and causes ulceration & trauma
on cheek or teeth that are hyper
erupted becoz of loss of teeth in
opposing arch.
16
17. Cont.
ī¯ Orthodontic reasons: Max. & Mand
PMs Mand. incisors are commonly
extracted.
ī¯ Cracked teeth: or with fractured root
ī¯ Preprosthetic extraction: teeth
interfering with design and
placement of full dentures, partial
dentures
17
18. Cont.
ī¯ Impacted teeth: that is unable to
erupt to functional occlusion.
ī¯ Supernumerary teeth: Impacted,
interfering with eruption of
succedaneous teeth or causing
resorption and displacement of
adjacent teeth should be extracted.
18
19. cont.
ī¯ Teeth associated with pathologic
lesions: If maintaining the tooth
compromises, complete surgical
removal of lesion.
ī¯ Pre - radiation therapy: remove
teeth in line of radiation therapy.
ī¯ Severe attrition, abrasion or erosion
19
20. Cont.
ī¯ Teeth involved in jaw #: If tooth is
severely luxated, tooth in # line
should be removed.
ī¯ Esthetics: Severely stained,
malopposed or protruding teeth are
removed.
ī¯ Economics: inability of PT to pay or to
take time from work may require the
tooth to be extracted
20
21. Contraindications for removal of
teeth

23
24. Clinical Evaluation of teeth for
removal
ī¯ Tooth to be extracted is examined to
assess difficulty of extraction.
ī¯ Access to tooth: if mouth opening of
PT is compromised-surgical
extraction.
ī¯ Mobility of tooth: teeth with less than
normal mobility should be assessed
for hypercementosis and ankylosis-
surgical removal
24
25. Cont.
ī¯ Condition of crown: if large portion
of crown is decayed by caries or
tooth with large amalgam
restoration, forceps is placed as far
apical as possible.
25
26. Cont.
ī¯ If large amount of calculus is
present on tooth, it should be
removed before extraction
otherwise it will interfere with
application of forceps or
contaminate socket after
extraction.
26
27. Cont.
ī¯ If adjacent tooth has amalgam
restoration or undergone endodontic
therapy, care must be taken while
using elevators.
27
28. Radiographic Examination of tooth
for removal
ī¯ IOPA shows portion of crown and root
of tooth under consideration
ī¯ If it is a I° tooth its relationship with
a succedaneous tooth should be
visible

ankylosed -so surgical extraction.
ī¯ Condition of surrounding bone
īŽ If more radio opaque- condensing
osteitis or sclerosis- so difficult to
extract.
ī¯ Periapical pathologies- should be
removed after extraction.
30
31. Patient & surgeon Preparation
ī¯ All patients should be considered as
having blood born disease.
ī¯ Surgeon should wear surgical gloves,
mask, eyewear with side shield, long
sleaving gowns.
ī¯ If surgeon has long hair it should be
covered with surgical CAP.
31
32. Order of extraction
ī¯ Lower teeth are removed before the
upper & posteriors are removed
before anteriors to prevent bleeding
from socket obscuring field of
operation (prof.J.Moore)
32
33. Methods of extraction
ī¯ Closed or intra-alveolar
ī¯ Open or transalveolar or surgical
ī¯ Stobie technique â extraction of
multiple mandibular anteriors by
using elevators b/w teeth
33
34. Chair position for forceps
extraction
ī¯ Best position is one that is most
comfortable to PT & to surgeon.
ī¯ Correct position allows surgeon to
deliver force with arm and shoulder
and not with hand.
ī¯ For Max. extraction,
34
35. Maxillary teeth
ī¯ Position of chair
īŽ Height of chair is such that height of
patient's mouth is at or slightly below
operator's elbow.
īŽ Chair is tipped backward that
Max.occlusal plane is 60° to floor
35
36. Cont.
ī¯ Position of patient
īŽ During procedures of Max. Right + left
quadrant PT's head is turned towards
operator.
īŽ For Max. Ant. Teeth, PT should be
looking straight ahead.
ī¯ Position of operator

handed operator & reverse in left handed
operator
36
37. Cont.
ī¯ Position of left arm
īŽ Left upper teeth, thumb supports the
palatal alveolar bone & index finger
retract the buccal tissues
īŽ Right upper teeth â thumb retracts the
buccal tissues & index finger supports
the palatal alveolar bone
īŽ In left handed operator the reverse
37
38. Mandibular teeth
ī¯ Position of chair
īŽ Chair is positioned in such a way that,
Mand. occlusal plane is parallel to floor.
īŽ Surgeon's arms are inclined downward at
an angle of 120° at elbow.
ī¯ Position of patient
īŽ In Mand. right post teeth-PT is turned
towards surgeon.
38
39. Cont.
ī¯ Position of operator
īŽ Mand. right post teeth, operator is
behind the pt &
īŽ In Mand. left post region, surgeon is in
front of PT.
īŽ Left handed operator the position is

40
41. Mechanical Principles Involved
in tooth extraction:
ī¯ Elevators I°rly works on lever
principle E.g straight elevator
ī¯ Wedge principle is also used when
elevator is used to luxate tooth.
ī¯ Wheel and axle principle is used by
triangular shaped elevators
E.g Cryer's elevator
41
42. Principles of forceps use
ī¯ Use of forceps:
īŽ To expand bony socket
īŽ To remove tooth
ī¯ Forceps should be placed below CEJ
ī¯ Traction towards least resistance
42
43. Cont.
ī¯ Alveolar purchase
īŽ By Kruger
īŽ For removal of anterior teeth or roots
īŽ After detaching the labial gingiva the
labial beak is placed under the tissues in
alveolar bone &apply pressure
43
44. Major Motions of forceps
ī¯ 1.Apical pressure: Tooth socket is
expanded by insertion of beaks down
into periodontal ligament.
ī¯ 2. Buccal pressure: produces
expansion of buccal plate and lingual
apical pressure
ī¯ Lingual pressure: Expands lingual
cortical plate and buccal apical
pressure.
44
45. Cont.
ī¯ Rotational pressure: Teeth with
single conical roots e.g. Max. incisors
Mand. PM, But the roots should not
be curved.
ī¯ Tractional force: For delivering tooth
out of socket.
45
46. Procedure for closed extraction:
ī¯ Requirements for extraction
īŽ Adequate access and visibility
īŽ Unimpeded pathway of removal
īŽ Use of controlled force.
46
47. General steps for closed
extraction
ī¯ Loosening of soft tissue attachment
from tooth
īŽ Done by a Periosteal elevator
īŽ Helps to assess anesthesia
īŽ Allows extraction forceps to be placed
apically.
47
48. Cont.
ī¯ Luxation of tooth with a dental
elevator:
īŽ A straight elevator is inserted to the
tooth into interdental space.
īŽ Strong, slow, forceful, turning of
handle moves tooth in posterior
direction causing expansion of bone
īŽ Tearing of periodontal ligament
48
49. Cont.
īŽ Excess force can damage or displace
adjacent tooth especially if it has a
large restoration or caries
ī¯ Adaptation of forceps to tooth:
īŽ Tips of forceps beaks should grasp root
īŽ Lingual beak is seated first.
īŽ Beaks must be parallel to long axis of
tooth
īŽ Force should be applied with shoulder &
upper arm & not with wrist.
49
50. Cont.
ī¯ Sterile drape should be put across
Pt's chest
ī¯ Before Extraction, PT should
vigorously rinse mouth with antiseptic
mouth rinse.
ī¯ 4X4 inch gauze can be placed in to
back of mouth to prevent teeth or
fragments falling into mouth
50
51. Cont.
ī¯ Luxation of tooth with forceps:
īŽ Major force should be directed towards
thinnest portion of bone.
īŽ Slow steady force is used.
ī¯ Removal of tooth from socket:
īŽ Done by tractional force usually given
buccally
51
52. Role of opposite hand
ī¯ Reflect soft tissues of cheek, lips and
tongue, give visibility.
ī¯ Protect other teeth from forceps.
ī¯ Stabilize PT's head
ī¯ Supporting and stabilizing mand. during
mand. extraction.
ī¯ Supports alveolar process and provide
tactile information about expansion of
alveolar process.
52
53. Role of assistant
ī¯ Helps to visualize and gain access, by
reflecting soft tissues and tongue
ī¯ Suction away blood, saliva, irrigating
solution
ī¯ Stabilize mandible
53
54. Specific Technique for removal
of Each tooth
ī¯ Maxillary incisor teeth:
īŽ They have conical roots.
īŽ LI may have a distal curvature for root.
īŽ Alveolar bone is thin over buccal side
and thick over palatal side.
īŽ After apical Pre. the force is given
buccally, less palatal force followed by
rotational force, no rotational force if
there is curvature.
īŽ Tooth is delivered in labial direction
54
55. Cont.
ī¯ Maxillary canine
īŽ Longest tooth in mouth
īŽ Root is oblong in C.S.
īŽ Bone on labial aspect is thin. So a
fragment of bone usually fractures from
buccal aspect when tooth is removed.
īŽ Buccal, palatal and a small amount of
rotational movement and removed in
labio - incisal direction.
55
56. Cont.
īŽ If Bone is detached from periosteum, it
should be removed.
īŽ If buccal bone is attached to periosteum,
it can be left, normal healing will occur.
56
57. Cont.
ī¯ Maxillary I PM
īŽ Single rooted with bifurcation to bucco-
lingual roots at apical 1/3
īŽ Most common root #
īŽ Buccal bone is thinner
īŽ Tooth should be luxated as much as
possible.
īŽ Apical, buccal, palatal movements,
palatal should be less
57
58. Cont.
ī¯ Maxillary II PM
īŽ Single rooted
īŽ Thin bone buccally and thick palatally
īŽ Buccal, palatal, bucco - occlusal
tractional force.
58
59. Cont.
ī¯ Maxillary molar
īŽ 3 roots,2 buccal roots are relatively
closer and palatal is divergent towards
palate.
īŽ Buccal cortical plate is thinner than
palatal.
īŽ Forceps have projection on buccal beak
to fit buccal bifurcation.
59
60. Cont.
īŽ Upper cowhorn forceps is used in teeth
with large caries or restoration.
īŽ More buccal force, less palatal force
removed with bucco occlusal tractional
force.
ī¯ II M similar anatomy except less
divergence for roots and removed in
similar way.
ī¯ Erupted III M. conical roots
īŽ Easily extracted by elevators alone
60
61. Cont.
ī¯ Mand. ANT. Teeth
īŽ Incisor roots are thinner and shorter and
canine roots are longer and heavler.
īŽ Bone on labial aspect of canine is
somewhat thicker.
īŽ Equal movements labially, lingually &
tooth is luxated by a rotational force &
extracted by labio-incisal tractional force
61
62. Cont.
ī¯ Mand. PMs
īŽ Roots are straight & conical
īŽ Bone thinner on buccal & thicker on
lingual aspect.
īŽ Buccal, less lingual, rotational and
occluso - buccal tractional force.
īŽ If any root curvature rotation is avoided
62
63. Cont.
ī¯ Mand. Molars
īŽ 2 roots and widely divergent for IM
īŽ Roots may converge at apical 1/3
īŽ Most difficult of all teeth to extract.
īŽ Apical, buccal, lingual and bucco occlusal
tractional force.
īŽ Lingual bone is thinner than buccal so
more lingual pressure
63
64. Cont.
īŽ Lower cowhorn forceps is used by
squeezing the bifurcation, buccolingual
movements can also be used.
ī¯ Erupted mand. III M. Conical roots
lingual plate is thinner, so more
movements are given lingually and
delivered in lingo occlusal direction.
64
65. Modification for extraction of I°
teeth
ī¯ Similar buccolingual movements
ī¯ Rotational movement is avoided for
multirooted teeth.
ī¯ Tooth is delivered in least resistant
path.
ī¯ If the roots embrace PMT crown,
sectioning of roots should be done
65
66. Post extraction care
ī¯ If any periapical pathology in
radiograph, and no granuloma
removed with extracted tooth,
periapical area is carefully curetted.
ī¯ If any debris, calculus, amalgam, tooth
fragment, in socket it is removed with
curette.
ī¯ Remnants of periodontal ligament &
bleeding bony walls improves healing.
66
67. Cont.
ī¯ Vigorous curettage delay healing by
causing additional injury
ī¯ Finger pressure is applied to buccal &
lingual cortical plates to compress the
socket, to prevent bony undercuts
ī¯ If there is excess granulation tissue
around gingival cuff, it should be
removed with curette or hemostat.
67
68. Cont.
ī¯ Sharp bony projections should be
smoothed with bone file.
ī¯ Moistened 2x2 inch gauze is placed
over extraction socket and it should fit
into the space that was previously
occupied by tooth. So that biting force
will give pressure, will cause
hemostasis.
ī¯ Larger gauze is placed if multiple teeth
extracted of opposing tooth is missing.
68
