Open tray impression technique for bone level implants.

  1. Place the impression post into the implant.

  2. Tighten the guide screw using the SCS screwdriver.

  3. Prepare tray by creating access holes for the impression post.

  4. Apply impression material around the impression post to ensure complete coverage.

  5. Fill tray with impression material and take the impression.

  6. Let the impression material cure.

  7. Using the SCS screwdriver loosen the guide screw within the impression post.

  8. Remove the impression from the patient’s mouth.

  9. The lab selects the corresponding analog and places the impression post into the implant analog, tightening the guide screw.

  10. Ensure precise alignment of the implant analog with the grooves of the impression post to avoid inaccuracies.

  11. Stabilize the retentive section of the implant analog while tightening the screw to prevent rotation.

  12. The impression is now ready to be used to create a model.

Closed tray impression technique for bone level implants.

  1. Place the impression post into the implant and tighten the guide screw using the SCS screwdriver.

  2. Place the polymer impression cap on top of the fixed impression post. The color of the cap must correspond to the color of the positioning screw in the post and the arrows must align in a buccal lingual direction.

  3. Push the impression cap in an apical direction until it clicks. The impression cap is now firmly seated on the impression post.

  4. Apply impression material around the impression post to ensure complete coverage.

  5. Fill tray with impression material and take the impression.

  6. Once the material is cured, carefully remove the tray.

  7. The impression cap remains in the impression material and is automatically pulled off from the impression post with the removal of the tray.

  8. Unscrew and remove the impression post from the patient's mouth. Mount the impression post onto the analog using the guide screw.

  9. Ensure the color code of the analog corresponds to the color code of the polymer cap in the impression material.

  10. Reposition the impression post in the tray.

  11. Gently push the impression post until you feel a tactile response of engagement.

  12. The impression is now ready to be used to create a model.
