This video is a part of a series of videos demonstrating the clinical steps in fabrication of a complete denture.
A primary impression is the first step in fabrication of complete dentures.
This video demonstrates a technique of primary impression using impression compound with a non perforated stock metal tray with impression compound. Alginate or irreversible hydrocolloid can also be used in a perforated stock metal tray.
The primary impression is used to construct a primary cast on which a custom tray is fabricated for the secondary or final impression.
