1. DEVELOPMENT OF
OCCLUSION(III self
correcting anomalies)
SUBMITTED BY

2. “Anomalies, which arise in child’s developing dentition during the
period of transition from predentate period to permanent dentition
period and get corrected on their own without any dental
treatment”`

3.  Classification of self correcting anomalies
is based on the period of development of
occlusion
PREDENTATE
PERIOD
DECIDUOUS
DENTITION
PERIOD
MIXED DENTITION
PERIOD
Retrognathic
mandible
Deep bite Anterior deep bite
Anterior open bite Flush terminal plane End on molar
relation
Infantile swallow Primate and
physiologic spacing
Mandibular anterior
crowding
Ugly duckling stage

4. Pre dentate period
 Retrognathic
mandible
Type of
malocclusion which
refers to an abnormal
posterior positioning of
the mandible.
* corrected by
increased pace of
forward growth of the
mandible as compared
to that of maxilla.

5.  Anterior open bite
It is defined as the
lack of incisal contact
between anterior teeth
when the mandible is
bought into full closure
OR
It is defined as
absence of vertical
overlap of lower
incisors when the
posterior teeth are in
full occlusion.

6.  Infantile swallow
(aka tongue between
gum pads)
the jaw are apart and
tongue is placed
between upper and
lower gum pads.
*this pattern changes
during first year of life
with the introduction of
solid food in diet

7. Deciduous dentition period
 Deep bite
-occur in initial stages of development
- Deep bite is accentuated by the fact that the deciduous
incisors are more upright than their succesors the
permanent incisors. The lower incisal edges comes in
contact with the cingulum area of maxillary incisors.
- Deep bite is later reduced due to
*Eruption of deciduous molar
*Attrition of incisors
*Forward movement of mandible due to
growth

9.  Flush terminal
plane
Presence of
flush terminal
plane in
deciduous
dentition
indicates normal
occlusal
relationship in
permanent
dentition

10.  Primate and
physiological
spacing
- Mesial to maxillary
canine.
- Distal to
mandibular canine.
*spacing in
primary dentition is
essential to normal
eruption and
alignment of the
larger permanent
succesors

11. Mixed dentition period
Anterior deep bite
Because of large
permanent incisor
and shedding of
primary molar.
* Alleviated
following exfoliation
of second primary
molar

12.  End on molar
relation
flush terminal
relation between
the deciduous
second molar
leads to the end
on relation of the
first permanent
molar.

13.  Mandibular anterior crowding
After exchange of canines alleviated
following exfoliation of second primary
molar

14.  Ugly duckling stage
due to eruption off maxillary canine at
8-9 yrs of age there is a transient of self
correcting malocclusion seen in max. incisor
region
* This condition usually corrects itself when
the canine erupts and the pressure is
transferred to the coronal area of the
incisors.
