Surgical Orthodontics:
                         Introduction
•    DEFINITION: Surgical orthodontics refers to the
     various surgical procedures carried out as a part of
     overall orthodontic treatment plan.
•    Used as an adjunct or in conjugation with orthodontic
     treatment
•    Can be carried out before, during or after completion of
     orthodontic treatment
•    Surgical procedures are usually carried out:
1.    To eliminate the existing etiologic factor
2.    As a part of treatment plan
3.    Facilitate correction of malocclusion by orthodontic
      techniques
4.    Stabilize orthodontic treatment results & prevent
      relapse
5.    To correct severe skeletal discrepancies

 MINOR PROCEDURES      MAJOR PROCEDURES
• Extractions           • Orthognathic
• Surgical exposure       surgeries- surgical
  (uncovering) of         correction of jaws

• Frenectomy              surgeries like

• Corticotomy             cleft palate & lip
                          repair surgery
Minor Surgical Procedures
  The main aim is to remove the
   etiological factors & facilitate
   correction of malocclusion by
    orthodontic appliances, help
stabilize post-orthodontic results &
          to prevent relapse
Extractions
The various extraction procedures
       carried out as a part of
     orthodontic treatment are:
       a. Therapeutic extraction
          b. Serial extraction
     c. Extraction of carious teeth
d. Extraction of malformed/ankylosed
                   teeth
 e. Extraction of supernumery teeth
   f. Extraction of impacted teeth

serial
extraction

•Serial extraction is a form of
interceptive orthodontic treatment
which aims to relieve crowding at
an early stage so that the permanent
teeth can erupt into good
alignment, thus reducing or
avoiding the need for later
appliance therapy

Different procedures has been
described by different authors such
as;
Tweed’s method 1966; 8years [DC4].
Dewel’s ,,       1978; 81/2yrs[CD4]
Nance’s ,,       1940;         D4C
Extraction of Supernumery,Impacted & Ankylosed
                     Teeth
  •The presence of supernumery,impacted &
  ankylosed teeth impede the normal
  development of occlusion & are important local
  causes of malocclusion.
  •Common supernumery teeth-
  mesiodens, lower -pm
  area>incisor>molar, upper-canine area
  Extraction of impacted canine-
  i. prior to extraction, a thorough radiographic
       examination must be done.
  ii. Depending on position approach by a well-
       designed buccal or palatal flap.
  iii. Elevate flap. After reflecting flap, remove
       bone around tooth.
  iv. Remove tooth atraumatically & irrigate
       extraction socket.
  v. Reposition flap & suture.remove suture          Post surgical removal of
       after a week                                  impacted maxillary right canine
Surgical Exposure of Impacted Teeth

• Canines- freq impacted
  teeth that req surgical
  exposure.
• Favourably located
  impacted canines can be
  guided to their normal
  positions in the dental
  arch by a combined
  surgical-orthodontic
  treatment referred to as
  surgical eruption
Surgical Techniques for
exposing Impacted Canines:
1. Window approach
   (gingivectomy)
2. Apically repositioned flap
   (ARF)
3. Flap closed eruption
   technique (FCET)
4. Tunnel traction (TT)

Steps in the management of
   an Impacted Tooth:
a. Determination of the
   position
b. Evaluation of favourability
c. Surgical exposure & bone
   removal
d. Fixing orthodontic
   attachments or direct
   ligation
Frenectomy
• Frenum Problems-Midline diastema between two
  maxillary central incisors (low frenum
  attachment/thick labial frenum)
• The frenum that is inserted palatally into the
  incisive papilla & balances on eversion of lip is the
  main etiological factor of diastema. Such frenum
  has to be exised.
• A frenectomy in this case should be followed with
  orthodontic treatment.
• The RULE!!!- The presence of a maxillary diastema
  does not prompt early frenectomy-WAIT UNTIL
  THE CANINES AND LATERALS ERUPT
Corticotomy
• Corticotomy is an adjunct surgery for
  malocclusion with wide generalised
  spacings.
• The buccal palatal flaps are raised.
• The vertical cuts are placed in the
  cortical bone parallel to the roots. These
  vertical cuts on both palatal & buccal
  side are joined by horizontal bone cuts
  that extend the depth of cortical bone.
• The sutures are placed & orthodontic
  appliance is placed after 2-3weeks.
• Now the tooth move within the
  cancellous bone and the treatment time
  is appreciably reduced.
PERICISION or CIRCUMFERENTIAL SUPRACRESTAL FIBROTOMY
(CSF)

 •It is an adjunctive
 procedure to prevent
 relapse following
 orthodontic treatment
 particularly rotational
 correction.
 •The supracrestal fibres are
 responsible for the relapse
 tendencies.
 •Pericision involves surgical
 transection of these
 supracrestal fibres.
