Cast impression coping technique.
A laboratory cast impression coping has been designed to capture accurate crown and bridge impressions, even in the most challenging circumstances. The designed technique is similar to copper band techniques and likewise does not require gingival retraction. The design includes a flat, nail-shaped head for proper finger pressure during the wash impression phase. Beads enhance the nail head design, allowing the impression-filled coping to be captured properly in the master tray or over-impression.
