Question

post-test
when repairing a tab, it is important to:
a. check the work time of the adhesive prior to use.
b. always avoid using adhesion promoter.
c. proceed with shaping before it is fully cured.
d. freehand shape it as accurately as possible.

Explanation:

To determine the correct answer, we analyze each option:

• Option A: Checking the work time of adhesive before use is important for proper tab repair as it ensures the adhesive is used within its effective time frame for bonding.
• Option B: Avoiding adhesion promoter is incorrect; adhesion promoters are often used to enhance bonding, so avoiding them isn't a good practice.
• Option C: Shaping before full cure may lead to improper bonding or damage as the adhesive needs time to set properly.
• Option D: Freehand shaping for accuracy is not practical or the right approach; proper tools and techniques (after cure or with proper timing) are better, and freehand may not ensure accuracy.

Answer:

A. Check the work time of the adhesive prior to use.
