DENTAL TEAM: Ken Upright, Oxford Crown & Bridge, LLC and Dr. Shelley Olson, DDS, FICD, Granville Family Dentistry, both in Oxford, NC RESTORATIVE PROBLEM: A female patient fractured the entire facial...See more surface and buccal cusp of tooth #4, which had an old MOD amalgam restoration. Due to a 2mm diastema, the entire mesial aspect of the crown would be exposed in the patient's smile, so shade quality was a foremost concern. TREATMENT PLAN: Because of her positive experiences with the material, Dr. Olson prescribed a Delta Zirconia full contour crown to restore tooth #4. High Translucent Delta Zirconia, used for fabricating full contour restorations, full contour bridges, inlays and onlays offers excellent translucency for these types of restorations. High Strength Delta Zirconia is also available for copings and two- to 14-unit bridges. FABRICATION PROCESS: Dr. Olson performed the appropriate build-up and prepared the tooth per suggested guidelines. Upright sent the articulated model and prescription to Aurident's Delta Milling Center for scanning, design and fabrication. Upon return, Upright checked contour and interproximal and occlusal contacts and used rubber wheels to give the crown a smooth finish. He then blasted the crown lightly to prepare the surface for stain and put it in an ultrasonic for about 10 minutes in a 10% acetone solution. For staining, Upright used the same materials he uses with traditional porcelain, but fired them 20-25°C higher. He prefers to accomplish occlusal anatomy staining and incisal/cusp staining in two separate firings so that they don't run together. Therefore, for the first firing, he concentrated on achieving a realistic, gradient body shade and occlusal anatomy stain. For the next firing cycle, he stained the occlusal and incisal portions, as well as cusp tips and occlusal slopes. Once he was satisfied with the basic shade, he applied a glaze powder used on zirconia-compatible porcelains for a third firing cycle, taking care to experiment with the consistency. If the glaze is too thin, it cracks on the surface; if it's too thick, it can appear milky and distort the shade. Once the crown was seated, the dental team and patient were extremely pleased with the results, particularly the nearly undetectable emergence profile and post-op tissue adaptation.
