President systems are silicone-based dental impression material, indicated as a tray material for use with any automated mixing machine. There are a range of different impression techniques that President material can use, including one step putty/wash (double mix), two step putty/wash, functional, transer coping, pick-up, relining, and impressions for implantology after healing.

Tray selection depends on the impression technique and personal preference of stock trays, double arch bite trays, or custom trays. Apply a thin layer of Coltene Adhesive onto the tray for optimum adhesion. The trays are clear, disposable, and rigid by design; they are indicated for all types of impression materials.
