Zirconia is becoming an integral, essential, and reliable material in restorative dentistry, as it offers many desirable properties that benefit both clinicians and patients—among them strength, durability, and esthetics. It also is metal-free and biocompatible, and esthetically, the shade is more opaque and lacks translucency. Together, these qualities make zirconia a wonderful choice for full-coverage crowns and bridges.
One Zirconia Disc, Many Indications
LayZir All Indication Zirconia Disc from Smart Dentistry Solutions has a natural, translucent gradation without compromising the qualities of zirconia. LayZir’s special blend of 3Y and 5Y yttrium-stabilized zirconia from the cervical to the body offers a translucency comparable to lithium disilicate. Additionally, a wide variety of shade and size options gives us more choices, especially for anterior cases. LayZir is not only indicated for anterior and posterior full-coverage crowns, but also for anterior partial veneers.
In my practice, Narita Family Dental, I frequently call on LayZir to create beautiful restorations for my patients. That includes the 3 anterior esthetic cases referenced here, all of which were milled by Haus Milling Center in Dallas, TX, with assistance from dental technician Rick Endo, CDT, of Plano, TX.
An Example of Esthetics
A 56-year-old woman presented to my office with a chief complaint of short, discolored teeth with flat incisal edges. After a thorough examination and discussion of treatment options with the patient, zirconia partial veneers from teeth Nos. 6 to 11 were indicated, and a LayZir 14-mm disc in shade C1 was used to create the restoration (Figures 1–3).
In another case, a 42-year-old woman came to the office who was unhappy with her discolored teeth and composite restorations with stained cervical enamel roughness. We opted for full-coverage zirconia crowns from teeth Nos. 6 to 11 using a 16-mm LayZir disc in shade A3 (Figures 4–6).
Another patient presented with exposed discoloration of receded cervical and embrasure areas. The patient, a 50-year-old woman, agreed to treatment of partial veneers on teeth Nos. 6 and 11, as well as full zirconia crowns on teeth Nos. 7 to 10. A 16-mm LayZir zirconia disc was used in shade B1, yielding a strong and highly esthetic final result (Figures 7–9).
