In “closed tray” impressions, on the other hand, the transfers remain attached to the implants after the impression material has been cured. In this technique, the transfers remain encased in the impression material after the impression has been removed from the patient’s mouth. The “ pick-up” technique is also referred to as the “open tray” technique. In the production of implant prosthetics, there are two main impression taking techniques: “pick-up” and “closed tray”.
