I like to wax them in place on the impression before pouring if the doctor takes a wash for processing.
As someone who processes using the above method, my jaw dropped when I read this in the the Air Force Manual, where everytime I peruse, I learn something new!
7.101.1.2. Create a posterior palatal seal as follows:
7.101.1.2.1. A posterior palatal seal is a feature incorporated into a maxillary denture to offset denture processing changes in the acrylic and improve denture retention. (NOTE: This seal is not recommended for the positive-pressure, injection-molded technique SR Ivocap®.) In processing, the denture acrylic shrinks away from the cast slightly. This shrinkage is most obvious along the posterior border of the maxillary denture. If compensation is not made for this distortion, the posterior border of the denture will not touch the patient’s tissue when the denture is placed in the mouth. As a result, air enters between the denture base and the mouth tissues, and the denture falls away from the patient’s ridge and the palate.

I couldn't believe my eyes, and everybody I've mentioned it to express their unwavering support of placing a post-dam no matter what. I want to try. Sounds like less work, better results to me. If it's in the Air Force Manual, you know it's legit.
