Occlusion Flashcards
What is occlusion?
Occlusion is the STATIC relationship of teeth
What is maximum Intercuspation
It is the complete intercuspation of the opposing teeth, INDEPENDENT of condylar position
What does habitual occlusion?
In CHEWING where the maximum contact between teeth occurs
Occlusal disease
It is a deformation or disturbance of function of any structure within the masticator system that are in this equilibrium with a harmonious interrelationship between the
TMJ
Masticatory musculature, and
the occlusing surface of teeth
Potentially damaging factors in occlusion
Marginal Ridge discrepancies
Extruded teeth
Wide occlusal tables resulting from excessive wear
Deep overbite with minimal overjet
Destructive occlusion forces can be reduced by
Selective grinding
Orthodontics
Restorative treatments
Tooth extraction
What’s important objective of occlusion adjustments?
To achieve a more favourable direction and distribution of forces of occlusion
Interferences
Should be corrected BEFORE starting any restorative treatment
