Split/Dual Tray Impression Technique with a Digital Workflow

Making an accurate impression is a crucial step in fabricating a removable prosthesis that fits the patient with retention, stability, and support. Numerous impressions materials and techniques exist for making dental impressions. The clinical technique discussed in this article utilizes a 3D printed custom tray, and a dual tray impression technique, to fabricate an immediate denture for a patient with terminal maxillary anterior dentition. This technique utilizes digital dentistry to make a well adapted impression that captures the anatomy of the soft tissue, functional margins, and compromised dentition using polyvinylsiloxane for the edentulous area and alginate for the dentate area.
