How To Choose Zirconia Blocks

When choosing zirconia blocks, there are several factors to consider, including the type of zirconia material, block size and shape, and shade and translucency. The two types of zirconia materials commonly used in dentistry are partially stabilized zirconia (PSZ) and fully stabilized zirconia (FSZ). PSZ is less stable than FSZ and is typically used for anterior restorations, while FSZ is more stable and is used for posterior restorations. Block size and shape are also important considerations. Dental laboratories need to choose blocks that are appropriate for the restoration they're creating. Additionally, the shade and translucency of the zirconia material must match the patient's natural teeth for the most aesthetically pleasing result.
