REPLACING A SINGLE POSTERIOR CROWN IN ONE APPOINTMENT
Case Report
Even though she is a dental hygienist, Nikole decided to wait it out when she was told her crown on tooth #15 had an open margin. But over time, she noticed the area started to shred her floss. That’s when she decided it was time for the crown to be replaced. Because the patient had high expectations for her restoration, I selected a BruxZir ® Esthetic NOW Posterior Milling Block for its combination of esthetics and strength. Though BruxZir Esthetic was originally developed with the anterior in mind, with a yttria content that enhances the overall translucency and color, the material still maintains an excellent flexural strength of 870 MPa, meaning it is sufficiently strong enough to be used anywhere in the arch.
