occlusion dental vs skeletal

1. Occlusion
• Normal relation of normal of the occlusal inclined
planes of the teeth when the jaw are closed.
• Types:
1. Ideal occlusion-theoretical concept
2. Physiological occlusion- deviates from ideal, still well
adapted
3. Balanced theraupeutic- non-physiological to
physiological
4. Traumatic- abnormal occlusal stress
5. Trauma from occlusion- occlusal forces through
abnormal contacts.

2. Malocclusion
• Types:
Intra-arch
Inter-arch
Skeletal

3. Intra-dental
• Malpositions of individual teeth in respect to
adjacent teeth within the same dental arch.
• Hence also called intra-arch malocclusion.

4. 1. Lingual
displacement
2. Buccal tipping
3. Lingual tipping
4. Linguodistal/
mesiobuccal
1. Trasposition 13
and 14

5. Inter-dental
• Malocclusion characterized by an abnormal
relationship between teeth or group of teeth
of one dental arch to that of the other arch.

6. 1. Posterior crossbite

7. Skeletal
• Malocclusion are caused due to the defects in
the underlying skeletal structure itself.
• Examples: Angle’s classification and Incisor’s
classification
1. Incisor’s
classification

8. 1. Angle’s classication

9. Dental Intra-arch Dental Inter-arch Skeletal -malocclusion
Variation in individual tooth
position and malocclusion
affecting a groups of teeth
within an arch.
Comprise of malrelation of
dental arches to one
another upon other dental
arch.
Abnormalities caused by
underlying skeletal
structure.
The defects can be in size,
position or relationship
between the jaw.
Examples: distal tipping,
MB rotation
Examples: overbite, cross-
bite
Examples: lower facial
height, retronagthism
