Over 50 years the developments, refinements, and process/material change have all been the response/request from clients.

Now taking an impression takes less time and the finished impressions are more durable and accurate.

The next step which came about was mixing a different powder and liquid, but it also had its drawbacks:

First the monomer and polymer would shrink giving the impression only about 30 days

Second the original was sold in bulk which gave the professional quite a bit freedom to adjust different amounts of liquid and powder

As you can well imagine the results varied greatly in the shape of the cured impression during transit to the lab.

Tune in next month for the next step we took!
