1. RETENTION
PLANNING
www.indiandentalacademy.com

2. Retention planning is divided into three
categories depending on the type of
treatment:
• No retention
• Limited retention in terms of both
time and appliance wearing
• Permanent or semi permanent
retention
www.indiandentalacademy.com

3. No Retention required
• Corrected cross bites: Anterior, Posterior
• Dentition that have been treated by serial
extraction.
• Corrections that have been achieved by
retardation of maxillary growth, whether
dental or skeletal.

4. • Dentitions in which the maxillary
and mandibular teeth have been
separated to allow for the
eruption of the previously blocked
out teeth.

5. Limited Retention
• Class I non-extraction cases
characterized by protrusion and
spacing of maxillary incisors; these
cases require retention until normal
lip and tongue function has been
achieved.

6. Limited Retention
• Class I or class II extraction cases
probably require retention, so that
the teeth be held in contact,
particularly in the maxillary arch,
until lip and tongue functions can
achieve a satisfactory balance, as in
the non extraction group

7. Limited Retention
• Corrected deep overbites, either in
class I or class II malocclusions,
usually require retention in a vertical
plane

8. Limited Retention
• Early correction of rotated teeth to
their normal positions.
• Corrected rotations in the mandibular
incisor area probably lend themselves
best to retention by a removable type
of appliance.
• Transseptal fibre surgery offers the
best possibility of stabilizing rotated
teeth.

9. Permanent or Semi
permanent Retention
• Cases in which expansion has been
the choice of treatment (particularly
in the mandibular arch)

11. Requirements
• It should retain each tooth that has been
moved into the desired position in
direction where there are tendencies
toward recurring movements.
www.indiandentalacademy.com

12. • It should permit the force
associated with functional activity to
act freely on the retained teeth,
permitting them to respond in as
nearly a physiologic manner as
possible
www.indiandentalacademy.com

13. • It should be as self-cleansing as
possible and should be reasonably
easy to maintain in optimal hygienic
condition.
• It should be constructed in such a
manner as to be as inconspicious as
possible, yet should be strong enough
to achieve its objective over the
required period of use.

14. • Removable: Hawley retainer
Wraparound retainer
Clipon retainer
Positioner
• Fixed
• Active retainers: Spring retainers

with molar clasps and an ant. Labial bow
with vertical adjustment loops located in
the canine region.
