Bicon Integrated Abutment Crowns™: Replacement of a Porcelain Fused to Metal Crown with an Integrated Abutment Crown™ in One Clinical Visit
This case demonstrates the replacement of an existing porcelain fused to metal crown on a maxillary left central incisor implant with an Integrated Abutment Crown™, which was inserted three years previously and was prone to loosening.
     


1. Pre-operative view.


2. Pre-operative radiograph of a maxillary left central incisor porcelain fused to metal crown.


3. View of patient’s smile after the removal of porcelain fused to metal crown.


4. A 3.0mm titanium impression post being seated into the well of an integrated implant for the making of an implant level transfer impression.


5. View of titanium impression post seated in the well of integrated implant.


6. A green 3.0mm plastic sleeve being inserted onto the 3.0mm titanium impression post.


7. View of seated green 3.0mm plastic sleeve which was inserted onto the impression post.


8. Impression material being injected around the impression sleeve for the making of a full arch implant level transfer impression.


9. Maxillary implant level transfer impression being removed from the mouth.


10. AAbutment post being cleaned with alcohol wipe to remove any debris which would diminish the effectiveness of the locking taper connection, prior to the insertion of Integrated Abutment Crown™.


11. Integrated Abutment crown™ being inserted initially to evaluate its appropriateness.


12. Floss being used to confirm the fact that the interproximal contacts are passive and will not interfere with the engagement of the locking taper.


13. Adjustment of interproximal contact since a too tight interproximal contact would prevent the engagement of the locking taper and possibly result in the subsequent loosening of the Integrated Abutment Crown™.


14. Well of implant being cleaned with alcohol on a cotton tipped applicator.


15. Yellow thermoplastic custom seating jig, which was formed with a crown alignment device, in a crown seating tip attached to a straight handle facilitates directing the tapping forces in the long axis of the abutment post and implant well.


16. Floss being used to confirm the fact that the interproximal contacts are passive and will not interfere with the engagement of the locking taper.


17. Blue markings indicate premature contact on the disto-facial as the mandible was being retruded while the patient was clenching.


18. Blue markings indicate the need for adjustment of Integrated Abutment Crown™ on distal-facial contact.


19. Note view of incisal contact while the mandible is in a different excursion position.


20. Post-operative radiograph.


21. Facial view immediately after the insertion of the Integrated Abutment Crown™.


22. Right profile view immediately after the insertion.


23. Left profile view immediately after the insertion.


24. Patient’s smile.
