Treatment planning

  • First Appt
    The patient presented to the office with an existing #46 crown that had a fracture line extending from the buccal to the lingual margin. It was recommended to redo the crown as it could not be repaired and was trapping food.

    The patient signed the consent form and agreed to proceed with a monolithic Zirconia crown. A preliminary alginate impression was taken in order to fabricate a temporary after preparation and 4 cc Xylocaine 2% with epinephrine 1:100,000 was administered. After the preparation, ozone air was infused over the tooth and then Clearfill bond was applied and light cured.

    Expasyl was utilized to retract the tissues and then washed away to allow good visibility of the margins.
    A final impression was taken with heavy body Affinis and light body President as we needed a quick turn around time from our lab due to the proximity of the Christmas holidays. The prep was temporized with Luxatemp A2 and was cemented with Flecks, just in case we could not see him until after the holidays.

    The occlusion was checked to make sure the temporary was in occlusal harmony with the other teeth and the temporary crown was polished.
    The shade chosen for the crown was Vita C2. The patient delivered his Vivera retainer and it was sent to the lab so that the crown was designed to fit the Vivera retainer.

  • Second Appt
    The patient presented for cementation of tooth #46 monolithic zirconia crown. The temporary crown was sectioned, removed and the crown was tried in. One bitewing was taken to check and verify the accuracy of the mesial and distal margins to the tooth preparation.

    The crown was evaluated for marginal adaptation, occlusal harmony in centric and balancing side contacts. The shade was very esthetic to the adjacent teeth and the patient was pleased. The consent form was signed. The tooth was microetched and coated with Universal All-Bond to seal the dentinal tubules and was light cured. The crown was treated with Z Prime. The crown was cemented with Rely X Unicem translucent, the excess was removed and the margins were light cured. The excess cement was removed and the occlusion was verified in both centric and lateral excursions, and the restoration was polished where the adjustments were made. The patient felt comfortable with the fit and esthetics of the crown.
