What Is Dynamic Occlusion

Dynamic occlusion is defined as the tooth contacts occur- ring during movement of the mandible. The objective of the examination of the dynamic occlusion is to detect any so- called dynamic occlusal vector—that is, any nonphysiologi- cal condylar movement that is imposed by the dynamic occlusion.

What does dynamic occlusion mean?

Dynamic occlusion is the study of the contacts that teeth make when the mandible is moving – contacts when the jaw moves sideways, forwards, backwards, or at an angle. … Although the jaw is moved by muscles, the contact lines depend on both the teeth positions and shapes (obviously), and the shape of the TMJ.

What is static and dynamic occlusion?

Static occlusion was determined for both incisal and molar relationship. Dynamic occlusion was determined in lateral and protrusive movements of the mandible. … Canine-guided occlusion was the dominant type of dynamic occlusion (57%) and most of the subjects had no posterior contact in protrusive movement (78%).
