What is protrusive movement? (2024)

What are the movements of the mandible?

[6] There are primarily 6 types of mandibular movement, including opening, closing, rightward jaw translation, leftward jaw translation, protrusion, and retrusion. Variability in jaw movement allows for mastication of different textures and consistencies.

What is translation movement of mandible?

Translation can be defined as a movement in which every point of the moving object simultaneously has the same direction and velocity. In the masticatory system, it occurs when the mandible moves forward, as in protrusion. The teeth, condyles, and rami all move in the same direction and to the same degree (Figure 4-5).

What are the 2 jaw movements?

TMJ Movements. Normal movements of the jaw during function, such as chewing, are known as excursions. There are two lateral excursions ( left and right ) and the forward excursion, known as protrusion, the reversal of which is retrusion.

What 4 movements are provided by the TMJ?

Movements. A variety of movements occur at the TMJ. These movements are mandibular depression, elevation, lateral deviation (which occurs to both the right and left sides), retrusion and protrusion.

What is Bennett movement?

The Bennett movement is part of this group of movements (23). It is a complex lateral movement or lateral shift of the mandible resulting from the movements of the condyles along the lateral inclines of the mandibular fossae during lateral jaw movement.

What is the meaning of translation movement?

a written text. 2 the act of translating or the state of being translated. 3 (Maths) a transformation in which the origin of a coordinate system is moved to another position so that each axis retains the same direction or, equivalently, a figure or curve is moved so that it retains the same orientation to the axes.

What are the 4 joint movements?

Synovial joints allow bones to slide past each other or to rotate around each other. This produces movements called abduction (away), adduction (towards), extension (open), flexion (close), and rotation.

What movement causes the mandible to open the mouth?
