 Institute for Dental Sciences:

During Jaw Relations Protrusive Records are used for?
A. Condylar inclination measurement of one side
B. Condylar inclination measurement of both sides.
C.Records Centric Relation.
D.Record retruded contact position

Ans. (B)

Protrusive Jaw Relation- A protrusive interocclusal record can register the influence of the condylar paths over the

movement of mandible. It enables the condylar guidances of the articulator to be set to an approximation of the

paths of condylar movements in the patient. Mandibular protrusive movements depend upon and must follow the

contour of glenoid fossae, which understandably does not resemble the straight line path of articulator.
