Fig. 43
Manipulate the mandible into centric relation and caution
the patient to keep his or her teeth separated to avoid
contact with the wax. Instruct the patient to slowly move
the mandible straight forward. After the patient has
protruded his or her mandible 4–6 mm, verbally instruct
the patient to close into the wax until “cuspal indents” have
been created.
Maintain this position while cooling the wax with a stream
of air until the wax is no longer soft, then instruct the patient
to “snap open.” Remove and examine the protrusive
record for:
a. The presence of adequate cuspal indents.
b. The absence of wax perforation and/or soft
tissue contact.

possible. Store the records in room temperature water until
ready for use.

may be taken into consideration when selecting appropriate
average guidance figures: 1
