Zirconia vs. Porcelain Wear Study
 
Zirconia vs. Porcelain Wear StudyDescription: Although conventional belief might suggest that zirconia's high fracture strength and surface hardness would cause a greater degree of wear on enamel, a recent study found that the degree of wear on the opposing tooth was actually four times greater in dental porcelain than in polished, unglazed zirconia, suggesting that zirconia restorations are not only more fracture-resistant than porcelain restorations, but also gentler in their functional interaction with natural dentition.

BruxZir® vs. Ceramco®3 – A Comparative Wear Study
 
BruxZir® vs. Ceramco®3 – A Comparative Wear Study Description: BruxZir Solid Zirconia and Ceramco3 were recently tested in a comparative wear study. Each material was tested using the Willytech Chewing Simulator, which simulated the clinical performance of the material over a period of five years. After 1.2 million wear cycles under a load of 5 kg, BruxZir compared favorably to Ceramco3 with barely detectable wear.

BruxZir® vs. IPS e.max® Enamel Wear Test
 
BruxZir® vs. IPS e.max® Enamel Wear Test Description: Some dentists are concerned about the wear of enamel when opposing BruxZir full-contour zirconia crowns and bridges. In a recent study1 to measure the volumetric loss of enamel, glazed BruxZir was found to wear compatible with enamel and virtually identical to glazed IPS e.max.

High Flexural Strength
 
High Flexural Strength Description: Lithium Disilicate ceramics have 400 MPa and typical zirconia materials have a flexural strength of more than 1200 MPa. However, because of post-powder processing, BruxZir Solid Zirconia dental restorations are able to exceed that strength threshold, with flexural strengths up to 1465 MPa.

Antagonist Wear Study
 
Antagonist Wear Study Description: The antagonistic (Steatite balls) wear shows BruxZir only with 72±21 micron, which is significantly lower than Ceramco® 3, with 110±48 micron. The University of Tübingen study was run using an eight chamber Willytec Chewing Simulator at 1.2 million cycles.

High Strength Crown Options
 
High Strength Crown Options Description: View a side-by-side comparison of high-strength crown options, and conduct your own analysis on how BruxZir compares visually to traditional PFM and Full-Cast restorations. While some patients may favor the esthetics of precious or non-precious metals, BruxZir presents a more lifelike tooth shade, making the final restoration nearly indistinguishable from natural dentition.
