Please classify the zirconia crown brands by cheap (low range), mid range and premium range. Is BruxZir the most premium zirconia crown on the market ? How does it compare to Lava? I’ve heard BruxZir is better because it’s made from one zirconia piece (hence stronger) and Lava is zirconia fused with porcelain (less strong) Is BruxZir popular among UK (London) dentists? If so can you recommend some dental practices in London that are familiar with it? Is BruxZir only crown or also veneer?
