Principles, techniques & complications

3. INTRODUCTION
Science the earliest period of history of the extraction of the
tooth has been considered a very formidable procedure by the
layman, & it is because of the horrifying experiences
associated with the tooth extraction in the past that even
today the removal of a tooth is dreaded by a patient almost
more than any other surgical procedure.
Many patients suffer from extractionfobia & are often difficult to
care for, despite modern methods of anesthesia.
Many dentists still believe that speed is essential when
extracting the teeth.

4. DEFINITION
• The ideal tooth extraction is –
The painless removal of the whole tooth, or
root, with minimal trauma to the investing tissues, so that
the wound heals uneventfully & no post-operative
prosthetic problem is created.
(Geoffray L Howe)

6.  The 1st dentist was an EGYPTIAN
– HESI RE (3100-2181BC)
The history of dental extraction forceps is very old and
goes back to the time of Aristotle (384 to 322 BC)
where Aristotle described the mechanics of oral surgery
forceps .This was over 100 years beforeArchimedes
studied and discussed the principles of the lever.

9.  until the 16th century, dedicated dentists did not exist and
dentistry was practiced by general physicians and barbers.
 A number of tools were invented for performing this procedure.
Dental Pelican, which was invented in the 14th century by Guy de
Chauliac and used until the late 18th century.

11. The instrument is a combination of the
attributes of the an extracting forceps and a
toothkey 1843 to 1863
In the 20th century, the key was replaced by
the forceps, which are still in use today

13. 1. Allen 1994 – caries in 48.8% cases – abscess
2. Periodontal diseases – in 40.7% cases – to prevent alveolar ridge
resorption
3. Tooth with necrosed pulp & periapical lesion – not responding to
endodontic treatment
4. Over retained deciduous tooth – but take radiograph first
5. Orthodontic purpose
6. Prosthetic purpose
7. Unrestorable tooth
8. Impacted tooth
9. Supernumerary tooth
10. Grossly decayed 1M / 2M – make room for 3rd molar

11. Tooth in fracture line
12. Teeth directly involved by cyst & tumor

14. 13. Teeth in the area of therapeutic irradiation
14. Teeth acting as foci of infection –
ex. – bacterial endocarditis
- rheumatic fever
RICHARDS (1932) – bacteremia after infected tooth extraction
OKELL & ELLIOTT (1935) – STREPTOCOCCUS VIRIDANS in
blood stream (75% of 40 patient)
Use of local anesthetic solution (vasoconstrictor) - rate of spread of
infection

16.  It may be judicious to delay the extraction until certain
local or systemic condition corrected or modified.
 In the era of antibiotics acute infection of odontogenic
origin are not considered as absolute contraindication of
immediate extraction.
 NUG / HERPETIC GINGIVOSTOMATITIS – spread of
infection & greater degree of systemic reaction.
 Previously irradiated area (within 1 year) – less trauma +
pre & post-op antibiotic prophylaxis

17. Other relative systemic contraindications –
 Acute blood dyscrasias – acute leukemia , agranulocytosis,
 Untreated coagulopathies – congenital or acquired
 Adrenal insufficiencies
 Within 6 months of myocardial infarction

• 5-10 min.
• uncooperative patients
• 30-45 min.
• No pre-op preparation
• Respiratory tract disease
• Cardiovascular diseases
LOCAL ANESTHESIA
General factors

29. Local factors
 Acute infection at the site of injection
 Hemangioma

30.  Is defined as –
removal of all micro-organisms from a given object.
 Hands of operator
 Instruments
 Operation area
 Engines, lights & chairs are inevitably sources of cross-infection.
 Use the sterile gauze /cloth – to change the position of light.

31. 1. Position of the operator –
- Stand erect , equal distribution of weight on both feet
- Force delivery – with arm & shoulder not with hand
- application of force without stress to shoulders & back
- generally on right hand side
- for Right posteriors – back side
- operating box

32. 2. Position of the patient –
make the patient comfortable on dental chair
3. Height Of Dental Chair –
maxillary teeth – 8 cm / 3 inch below the shoulder level
of operator
mandibular teeth – 16 cm / 6 inch below the elbow of
operator

33. 4. Angulation of the chair –
maxillary teeth – 45-60 degree
mandibular teeth – parallel or 10 degree
5. Light –
good illumination

34. 6. Role of opposite hand
 Reflection of soft tissue
 Protection of other teeth
 Stablization of patient’s head
 Supporting & stablizing the mandible
 Supports alveolar bone
 Tactile information
 Compress socket
 Deliver the whole tooth, root, dislodged filling

35. 7. Role of assistant
 Helps the surgeon to gain access & visualize the field
 Suction
 Protect the teeth of opposite arch
 Support the head
 Support the mandible
 Psychological & emotional support
 Avoid casual , offhand comments
– increase patient’s anxiety
- decrease patient’s cooperation

36.  Clear access to & vision of the surgical field.
 Use of controlled force
 Unimpeded path of removal

38.  Separation of tooth from alveolar bone with
crestal & principal periodontal fibers.
 Alveolar expansion
 Bleeding is arrested by pressure pack.

39.  Severing SoftTissue Attachment
The straight and curved desmotomes

40. Chompret elevators;
a straight, and b curved

41. A. Intra-alveolar extraction (closed
technique)
B. Transalveolar extraction (open
method)

42. 1. forcep Technique
2. elevator Technique

43.  Commonly used
 Not used in – hypercementosis
- root deformities
- grossly decayed crown
- grossly decayed root
- brittle root
 Advantages - least trauma
- gingival fibers reduces the size of extraction orifice
so promotes healing

44. 1. Beaks should seated as far apically as possible
2. Beaks should be parallel to the long axis of tooth
3. Excess force should be avoided.
HOWTO HOLDTHE FORCEP
Thumb – just below the joint
Handle in palm
Little finger – inside the handle

46.  Buccally & lingual parallel to long axis of tooth.
 Forced through periodontal membrane, towards apex.
 Firm pressure.
 1st apply on less accessible side of tooth under direct vision
 2ndly on other side
 Cervical caries - 1st movement towards carious part

47. Time spent in careful application of forcep
blades to the radicular portion of tooth is
never wasted.

48.  Pressure applied by the operator by moving his trunk
from hips not from elbow.
 Movements – linguobuccal & buccolingual
- firm, smooth & controlled
rotatory / figure of 8
loose
removal

49.  Maxillary buccal bone is thinner – buccally removal of teeth
 Mandibular buccal bone till molar is thinner - buccally removal of
teeth
 Mandibular buccal bone in molar region is thicker - lingually
removal of teeth
 Socket compression
 Avoid soft tissue laceration

51.  In multiple extraction cases canine should be extracted
prior to extraction of incisors, as prior extraction of
incisors weakens the labial cortex.

55.  Heavy bladed forceps are
used.

59. Factors –
1. Permanent successors
2. Limited access
So use fine blades

127.  Piezosurgery is an innovative bone surgery technique that produces
a modulated ultrasonic frequency of 24 to 29 kHz, and a
microvibration amplitude between 60 and 200 mm/s.
 The amplitude of the vibrations created allows a very clean and
precise surgical cut.
 It works selectively, without harming soft tissues such as nerves and
blood vessels even with accidental contact with the cutting tip.
 The surgical control of the device is effortless compared with
rotational burs or oscillating saws because there is no need for an
additional force to oppose rotation or oscillation of the instrument.

128.  Despite the longer time of the procedure, the investigators also
noted that the piezoelectric osteotomy reduced postoperative
facial swelling and trismus.
 Uses of piezosurgery device to cut and elevate a precisely defined
bone lid on the lateral cortex of the mandible to provide access to
the teeth needing extraction or even a lesion that needs to be
excised. The bone window is then elevated with the help of a curved
osteotome.
 After the visual confirmation of an undamaged IAN and adjacent
tissues, the bone lid is placed back into its original position and
fixated with absorbable miniplates.

131.  For the surgical extraction of the teeth, the covering bone was first
ablated, layer by layer, using the Er:YAG laser.
 In the case of the fiber-optic Er:YAG [erbium:yttrium-aluminum
garnet ], laser the fiber is closely guided around the teeth, creating a
narrow gap with minimal bone loss.
 The benefits of laser therapy include the creation of a bloodless
surgical field and thus improved visualization during surgery,
decreased postoperative pain, and limited scarring and contraction.
 Time consuming, sound and smell, significantly inhibition the
laser cutting because of the overall volume of irrigation and blood
covering the bone surface.

132.  Third molars in close proximity to the IAN have a significant
negative impact on recovery for pain and oral function.
 The advantage of this technique is that the risk of direct trauma
to the nerve is eliminated, due to both the increased distance
between the roots and the mandibular canal and the decreased need
for surgical manipulation during the extraction.

133.  A potential problem with this technique is soft tissue damage from
impingement on the mucosa of the cheek and the gingiva.
 In addition, working in this area of the mouth presents great
difficulty, and the action of the masseter muscle leads to cheek
compression against the orthodontic appliances.
 This technique will be of no value for a tooth that cannot move
because of ankylosis.
 This technique should be used only in carefully selected cases in
conjunction with an orthodontist, being certainly difficult, time
consuming, and not always successful.

135. Panoramic radiograph at initial consultation. The mandibular
third molars are mesially impacted with the roots close to
the alveolar canal.

Postoperative radiograph after the right mandibular
third molar was surgically sectioned. The space
distal to the second molar would allow mesial
migration of the impacted tooth.

137. 3 months after odontectomy. The
third molar moved mesially.
However, the mesial root was still
in contact with the alveolar canal.
A second sectioning was required.
Periapical radiograph obtained 2 months after
second sectioning. At that time, the roots were
away from the alveolar canal, and a riskless
extraction could be scheduled.

138.  The Physics Forceps uses first-class level mechanics to atraumatically
extract a tooth from its socket.
 One handle of the device is connected to a “bumper,” which acts as a
fulcrum during the extraction.
 Together the “beak and bumper” design acts as a simple first-class
lever.
 A squeezing motion should not used with these forceps. By contrast, the
handles are actually rotated as one unit using a steady yet gentle
rotational force with wrist movement only.
 Once the tooth is loosened, it may be removed with traditional
instruments such as a conventional forceps

• Coronectomy is a technique that should
be considered for mandibular third molars
when it is felt there is an increased risk of
injury to the inferior dental nerve.
• Coronectomy is oral surgery’s approach
to minimal interventional dentistry.

142.  Coronectomy can be beneficial but success requires both good patient
selection and operator technique.
 Renton et al.reported no IDNI in 58 successful Coronectomy patients
and a 19% IDNI rate in those having traditional extractions.
 Leung et al. showed nine (5%) patients in the control group presented
with IDNI, compared with one (0.06%) in the Coronectomy group.
 Hantano et al. reported that in the extraction group six patients (5%)
suffered IDNI, of which 3 patients were diagnosed with permanent
injury, where as in the Coronectomy group one patient (1%)
complained of altered sensation post-operatively which resolved within
one month.
 The retrospective analysis of O’Riordan consisted of 52 patients that
underwent Coronectomy. In this study there were 3 cases of transient
IDNI which showed resolution one week post operatively. One patient
developed permanent IDNI, which was thought to be as a result of
perforation of the canal due to operator error rather than the
Coronectomy technique itself.

143. 1, deviation of the canal 2, narrowing of the canal

cement-enamel junction (arrow);
B, trimming cutting surface to less
than 3 to 4 mm below alveolar crest.

145.  To avoid traumatizing the surrounding bone during elevation,
implant drills were placed in the root canals to thin the root walls
giving way to extraction with the application of much less force,
thereby decreasing the chance of traumatizing the thin buccal bone.

encapsulated.

162. Reflect the soft tissue flap on lingual aspect of mandible as
forward to the premolars
gently dissect the mucoperiosteum
Detach the mylohyoid muscle.

163. If the root is not appearing in the oral cavity/pressure pack
 Ask the patient to cough & spit
 Turn the patient towards the operator & position with the
mouth towards the floor.
 Radiograph of alveolar socket/ sinus/ chest
 Re-examine the patient after 3 days

176.  Mostly 1–3 days after tooth extraction .
 Within a week - In 95% and 100% of all cases.
 Unlikely - before the first postoperative day.
because the blood clot contains anti-plasmin that must be
consumed by plasmin before clot disintegration can take place.
 The duration of alveolar osteitis varies to some degree, depending on
the severity of the disease, but it usually ranges from 5–10 days.

177. 1. The denuded alveolar bare bone may be painful and tender.
Initially blood clot appears dirty gray disintegrates
grayish yellow bony socket bare of granulation tissue
2. Some patients may also complain of intense continuous pain
irradiating to the ipsilateral ear, temporal region or the eye.
3. Regional lymphadenopathy (occasionally).
4. unpleasant taste (occasionally).
5. Trismus is a rare occurrence in mandibular third molar extractions
probably due to lengthy and traumatic surgery.

178.  Multifactorial origin
 Following have been implicated most commonly as etiological,
aggravating and precipitating factors:
1. Oral micro-organisms - Treponema denticola
2. Difficulty and trauma during surgery
3. Roots or bone fragments remaining in the wound
4. Excessive irrigation or curettage of the alveolus after extraction
5. Physical dislodgement of the clot
6. Local blood perfusion & anesthesia
7. Oral contraceptives - estrogens, like pyrogens will activate the
fibrinolytic system indirectly.
8. Smoking

179. 1. Previous experience.
2. Deeply impacted mandibular third molar (risk factor is directly
proportional to increasing severity of impaction) .
3. Poor oral hygiene of patient .
4. Active or recent history of acute ulcerative gingivitis or pericoronitis
.
5. Associated with the tooth to be extracted .
6. Smoking (especially >20 cigarettes per day) .
7. Use of oral contraceptives .
8. Immunocompromised individuals .

184. References in the literature correlating to the
prevention of alveolar osteitis can be divided
into
1. Non-pharmacological and
2. Pharmacological preventive measures.

185. Non-pharmacological
measures
1. Use of good quality current preoperative radiographs
2. Careful planning of the surgery
3. Use of good surgical principles
4. Extractions should be performed with minimum amount of
trauma and maximum amount of care
5. Confirm presence of blood clot subsequent to extraction
(if absent, scrape alveolar walls gently)

186. 6. Wherever possible preoperative oral hygiene
measures to reduce plaque levels to a minimum
should be instituted
7. Encourage the patient (again) to stop or limit smoking
in the immediate postoperative period .
8. Advise patient to avoid vigorous mouth rinsing for the
first 24 h post extraction and to use gentle
toothbrushing in the immediate postoperative period .
9. For patients taking oral contraceptives extractions
should ideally be performed during days 23 through
28 of the menstrual cycle .
10. Comprehensive pre- and postoperative verbal
instructions should be supplemented with written
advice to ensure maximum compliance .

187. 1. Antibacterial agents -
2. Antiseptic agents and lavage Chlorhexidine (CHX)
3. Antifibrinolytic agents - para-hydroxybenzoic acid (PHBA),
4. Steroid anti-inflammatory agents - polylactic acid (PLA)
5. Obtundent dressings
6. Clot supporting agents

188. 1. Remove any sutures to allow adequate exposure of the extraction site.As
the socket may be exquisitely tender local anaesthesia may be required.
2. Irrigate the socket gently with war sterile isotonic saline or local anaesthetic
solution, which is followed by careful suctioning of all excess irrigation
solution.
3. Do not attempt to curette the socket, as this will increase the level of pain.
4. Prescription of potent oral analgesics.
5. The patient is given a plastic syringe with a curved tip for home irrigation
with chlorhexidine solution or saline and instructed to keep the socket clean.
6. Once the socket no longer collects any debris, home irrigation can be
discontinued.

189.  Under block anesthesia
 The clot devoided socket is thoroughly curetted, both from the
floor of the socket as well as from the bony walls.
 The sharp margins were trimmed, rounded.
 Any foreign bodies if present were thouroghly removed.
 The detached gingival margins were also scraped.
 The desired medications as well as precautions .
 Patient was not only without pain, but was also comfortable both
physically as well as psychologically from the very next day.
