Another Use for ANTERIOR<br />
BruxZir ® Solid Zirconia Restorations<br />
– ARTICLE by Michael C. DiTolla, DDS, FAGD<br />
One of the most difficult clinical situations restorative dentists face in<br />
clinical practice is treating a patient with severe tetracycline staining.<br />
I treated one of these patients a few years ago with a set of veneers<br />
that were conservative but an esthetic compromise. The tetracycline stains<br />
showing through the veneers were still visible enough to bother the patient.<br />
When we removed the veneers six months later, I prepped 0.6 mm deeper to<br />
make the veneers thicker. But at the try-in appointment, it was clear that the<br />
esthetics hadn’t improved much from the first set. We ended up using lithium<br />
disilicate crowns, which provided an improved result, but there was still some<br />
minor show-through in the gingival third.<br />
Not long ago, the patient’s brother came to see me. He was already prepared<br />
to do crowns, so I wanted to see if BruxZir ® Solid Zirconia crowns (<strong>Glidewell</strong><br />
Laboratories) could block out the prep shade. While not as esthetic as lithium<br />
disilicate crowns, I hoped to get a more esthetic overall result by entirely<br />
blocking out the stump shade. Unlike his sister, this patient had fractured nearly<br />
every PFM in his mouth, and the wear in his mouth and his edge-to-edge<br />
bite clearly revealed a severe bruxing habit. Taking this into consideration,<br />
I knew BruxZir Solid Zirconia was the only ceramic material that would stand<br />
a chance of surviving in this hostile oral environment.<br />
