All-Ceramic Crown: Maxillary Molar
All-ceramic crown restoration of a single maxillary molar using a Bicon aluminum oxide sleeve.
     


1. 5.0mm shouldered abutment with a subgingival shouldered margin placement.


2. Seated one-piece acrylic sleeve.
The flat sides on the top of the sleeve correspond to the sleeve’s internal flats that, in turn, correspond with the external flats on the abutment and its analog..


3. One-piece sleeves may be used for temporization without the use of temporary cement. They may be used for transfer impressions, occlusal registrations, corrective copings, and as waxing sleeves. When used as waxing sleeves their external surface should be entirely covered with wax.


4. Impression material being injected around one-piece acrylic sleeve for the making of a transfer impression.


5. White polycarbonate abutment analog seated in one-piece acrylic sleeve within transfer impression.


6. Soft-tissue model material being injected around abutment analog.


7. Abutment analog in stone model without soft tissue material.


8. Bicon aluminum oxide sleeve on abutment analog.


9. Bicon aluminum oxide sleeves are readily cut or modified in seconds by placing the sleeve onto an abutment in its prep holder while holding it against the rotating diamond wheel of a model trimmer.


10. Finished all-ceramic crown on abutment analog.


11. Finished all-ceramic crown built on Bicon aluminum oxide sleeve.


12. Cemented all-ceramic crown.


13. Radiograph of all-ceramic crown.
