In taking interocclusal wax record in PROTRUSIVE position, what should be checked?

That the wax is of the correct temperature
That the patient has not closed in a lateral position
That the wax is of the correct hardness
That the patient's eyes are closed

The correct answer is: That the patient has not closed in a lateral position

In order to properly record interocclusal wax in the protrusive position, the patient should not close their jaw in a lateral position. This is because the protrusive position is used to determine the relationship between the upper and lower jaw, and any lateral movement can alter this position and result in an inaccurate record. Options A, C, and D are not directly related to the specific task of taking an interocclusal wax record, making them incorrect choices. It is important to ensure the wax is at the correct temperature and hardness, but those factors do not specifically pertain to the recording process in the protrusive position. Similarly, checking if the patient's eyes are closed is not relevant to the task and does not affect the accuracy of the record. Therefore, option B is the correct and most relevant choice.
