Single-Tray Impression Technique for Implant-Supported Overdentures

Figure 1. Custom tray was fabricated with acrylic resin and an access opening for the impression coping screws. Figure 2. Custom tray was used to verify that adequate space existed between the custom tray and the impression copings. Figure 3. Completed definitive impression with laboratory analogs fixed to the pick-up impression copings. Figure 4. Definitive cast created using the single-tray impression technique. Figure 5. Labial index shows the positional relation between the teeth and implants. Figure 6. Virtual design of computer-aided design/computer-aided manufacturing (CAD/CAM) bar with 5 locators. Figure 7.
