Indirect Abutment Level Impression with Plastic Sleeve

 

1. Definitively seat the abutment with a gentle tapping force. Snap impression sleeves onto the unmodified abutment.

2. Inject impression material around the impression sleeves and make impression.

3. Orientate the external flat(s) of the colored abutment transfer die with the internal flat(s) of the correspondingly colored non-shouldered impression sleeve prior to snapping it into the impression. It is imperative that the correct abutment transfer die be used. The diameter and height of the transfer die should match the diameter and height of the abutment.

4. Pour a soft tissue or stone model.

5. Snap the appropriate impression sleeve or temporization sleeve onto the colored abutment transfer die and modify as necessary.

6. Incorporate the sleeve into the wax pattern for the metal casting.

7. Try-in metal casting for a passive fit.

8. Apply porcelain following normal layering techniques until the crown is completed.

9. Final view of cemented Ceramo-Metal restoration.

 

 

Keys to Success

  • The diameter and height of the transfer dies are sized to match the diameter and height of the abutments.
  • It is paramount that the proper abutment transfer die height be chosen to pour the stone model since all transfer dies of the same color will snap into the impression sleeve of that color.
  • The temporization sleeves are more retentive than the impression sleeves.
