ARTICULATORS 1

When the horizontal condylar guidance inclinations are not determined by protrusive records, then it is set at 16°

Bennet angles are calculated using the Hanau formula (L)=H/6+12

Lateral condylar guidance guides the sideward or lateral movement of the mandible

An articulator is a mechanical instrument that represents the temporomandibular joints and arch

The adjustable elements of the semi-adjustable articulator

The horizontal condylar guidance inclination is adjusted from the protrusive relation record taken from the patient.

On the articulator, the mandibular jaw member is movable and the maxillary jaw member is stationary.

The face-bow assists in correctly transferring the inclination of the occlusal plane to the articulator.

The anterior guidance is a relationship between the lower and upper teeth of a  patient in eccentric movements

The occlusal record should

A face-bow is an instrument used to record the relationship of the maxillary ridge to the axis of the condyles

Before the lower cast is repositioned in the articulator, the incisal pin must be adjusted below the zero line.

At the center of the face-bow frame is a face-bow fork for attaching the registration joint (jack clamp) .

The role of the anterior guidance is to protect posterior teeth during centric mandibular movements.

When using the bio art articulator, the support of the transfer replaces the pin

The fork support is placed on top of the fork during articulation

The face-bow registration allows for an accurate record of the mandibular distance from the condylar axis.

Adjustments of the incisal guide are determined by the horizontal and vertical overlap of the anterior teeth
