CRYSTAL High Translucency blocks are the most translucent zirconia materials available, allowing 20-30% more light to pass though than other zirconia materials. In recent decades, full ceramic restorations have become increasingly popular due to their aesthetic properties. Ceramic materials have a tooth-like transparent appearance and can be shaded to match the patient’s natural tooth color. Today, many dentists use all-porcelain crowns, especially for anterior teeth. The problem with these materials, however, is their potential to fracture under stress, which is why they are not recommended for posterior crowns and bridges. CRYSTAL High Translucency zirconia blocks are up to FIVE TIMES STRONGER than all-porcelain materials, and provide life-long strength plus the aesthetic qualities patients seek. For long lasting patient solutions, CRYSTAL recommends zirconia frameworks for all crowns and bridges, fabricated with a super-strong 0.5 mm wall thickness for posterior crowns, and optionally, a thinner and more translucent 0.3 mm wall thickness for anterior restorations.
