## What is the Bennett movement?

The Bennett movement is defined as “The bodily lateral movement or lateral shift of the mandible resulting from the movements of the condyles along the lateral inclines of the mandibular fossae in lateral jaw movements. “’ McCollum’ considered the Ben- nett movement the most important determinant of occlusion.

## How is Bennett angle measured?

The Bennett angle is the angle measured in the horizontal plane between the sagittal protrusion path and the mediotrusion path of the condyle .

How much is a Bennett angle?

The average Bennett angle value in this study was found to be approximately 8 degrees. This information should be considered when programming average values into an articulator with respect to desired negative error (shorter cusp) during restoration fabrication.

### What is hinge axis?

The hinge axis is an imaginary line around which the condyles can rotate without translation. Terminal hinge position is the most retruded hinge position and it is significant because it is a learnable, repeatable and recordable position that coincides with the position of centric relation.

### What is angle of hinge rotation?

The mean angle of hinge axis rotation at maximum opening was 30 degrees in dentulous subjects and 17 degrees in edentulous subjects.

What does a Facebow do?

A facebow is an instrument that records the relationship of the maxilla to the hinge axis of rotation of the mandible. It allows a maxillary cast to be placed in an equivalent relationship on the articulator (Fig. 9-3). To identify the hinge axis, it is necessary to use a hinge axis locator and hinge axis facebow.

## What is Bennett angle in anatomy?

Ben·nett an·gle. the angle formed by the sagittal plane and the path of the advancing condyle during lateral mandibular movement as viewed in the horizontal plane.

## What is an angle in geometry?

In-plane geometry, an angle is the figure formed by two rays, called the sides of the angle, sharing a common endpoint, called the vertex of the angle. An angle is denoted using the symbol ∠.

What is Bennett movement according to Norman G Bennett?

Norman G., English dentist, 1870-1947. Bennett angle- the angle formed by the sagittal plane and the path of the advancing condyle during lateral mandibular movement as viewed in the horizontal plane. Bennett movement- the bodily lateral movement or lateral shift of the mandible during a laterotrusive movement.

### What does Bennett mean in dentistry?

Bennett, Norman G., English dentist, 1870-1947. Bennett angle- the angle formed by the sagittal plane and the path of the advancing condyle during lateral mandibular movement as viewed in the horizontal plane. Bennett movement- the bodily lateral movement or lateral shift of the mandible during a laterotrusive movement.
