4. Anchorage control - important
aspects of orthodontic treatment.
Extraoral anchorage devices
requires full patient cooperation -
sometimes not possible,
unpredictable.
Introduction of implants in
orthodontics have solved this problem
and become one of the best sources of
reliable anchorage.

6. ?
• A device that is temporarily fixed to
bone for the purpose of controlling
tooth movement during orthodontic
treatment and removed when the
treatment is completed.
• titanium-alloy mini-screws, 6 to 12
mm in length and 1.2 to 2 mm in
diameter.

7. • Can be located transosteally,
subperiosteally, or endosteally; and they
can be fixed to bone either mechanically
(cortically stabilized) or biochemically
(osseointegrated).
•Mini implants, Microimplants, Skeletal
anchorage

9. Size & Shape
• Conical (Cylindrical)
• a) Miniscrew Implants
• b) Palatal Implants
• c) Prosthodontic
Implants
• Mini plate Implants
• Disc Implants
(Onplants)
Implant Bone
Contact
• Osteointegrated
• Non-
osteointegrated
Application
• Orthodontic
purposes.
(Orthodontic
Implants) or TAD
• Prosthodontic and
orthodontic
purposes.

12. • Used for retraction of anterior teeth (Class II Div I)
• Uprighting of molars
• Mesiodistal tooth movement
• Open bite correction (archived by intruding posterior)
• Molar Mesialization
• Distalization of 1st and 2nd molars (Graz implant
supported pendulum: GISP)
• Intrusion of anterior teeth as well as molars
• Onplants for expansion and protraction of maxilla

15. CHARACTER CONVENTIONAL IMPLANTS
Anchorage Teeth and extraoral bony
structures
Implants
Stability Not stable Stable
Number of Anchor
Teeth
Maximum number
teeth must be included
For direct anchorage teeth are
not necessary, minimal
number of teeth are needed
for indirect force on implant
anchorage
Treatment Efficiency Applying force on teeth, part of
it
is wasted, due to periodontal
amortization
More efficient as force is
transmitted directly to the
implant
Duration Prolonged Shortened
Patient's
cooperation
Obligatory Minimal
Acceptability Most of treatment devices
restrict
patients motion, don't meet
esthetical requirements
Discomfort for patient is
minimal

17. 1. Can not afford any movement of reactive units
(maximum anchorage case)
2. Several missing teeth making it difficult to engage
posterior units
3. For difficult tooth movements, eg intrusion of
anterior and posterior segments and distalization
4. Where asymmetrical tooth movement is needed
5. To treat borderline cases with non extraction
method
6. Doing extreme orthodontics when patient is not
willing to undergo orthognathic surgery.

19. Implants have revolutionized the field of
anchorage in orthodontics.
So by choosing a correct anchorage source
we can get good results in orthodontic
Treatment.
