This video demonstrates the detail and care taken to capture the finish line or margin of an anterior crown preparation. Due to a failed previous full porcelain crown restoration that finished deep beneath the gumline, Drs. Paquette and Sheets show how the gum tissue was carefully retracted with a very delicate retraction cord and then the crown preparation was ready for the final impression to be taken. Notice how there was no trauma or surgery necessary as the dental microscope allowed the area to be visualized and precisely managed with minimal invasion of the biologically delicate gum tissues.
