Question 28

What is the difference when a wax pattern is made in the mouth versus a pattern that is made outside in the mouth? (Indirect and direct)?

Answer 28

A wax pattern made in the mouth (direct technique) will shrink appreciably as it is cold to room temperature. A wax pattern made by the indirect method may not shrink as much.

Question 29

Why does the direct technique is rarely used in producing wax inlay patterns?

Answer 29

It is because of the wax sensitivity to changes in pressure temperature and heating and cooling rates during manipulation because the direct technique will shrink as it is cooled to room temperature
