For me, every motion, movement, or step must have a rationale for its performance. In this instance the use of polyvinyl siloxane putty aids in the maintaining of contour established in wax and shortens the period of time needed to finish the case. The final prosthetic must reflect every contour evaluated in the try-in with no change. Clinicians evaluate not only tooth lengths but negative space, smile lines, and lip support, all influenced by loss of bone support being replaced with acrylic. Dentures may look easy on the surface but there are many nuances that effect the final outcome.
