Info

Structures control mandibular movement • Posterior controlling factor : TMJ • Anterior controlling factor : anterior teeth • Posterior teeth – are positioned between these two controlling factors – can be affected by both to varying degrees
Posterior controlling factors Condylar guidance – is the angle at which the condyle moves away from a horizontal reference plane from CR along the articular eminence <strong>of</strong> the mandibular fossa – depends on the steepness <strong>of</strong> the articular eminence – considered to be fixed factor, unalterable
