Occlusion is established between the ages of 6 and 18. Because existing fixed restorative materials are harder than natural teeth, restoration with existing fixed restorative materials during the occlusal period will cause excessive wear of the natural teeth in the opposite jaw. Hyperporcelain/fiber crowns and bridges are fiber-reinforced composite resins whose modulus of elasticity and hardness are slightly lower than that of enamel, which does not result in excessive wear of the opposing teeth, and is especially suitable for children and adolescents whose occlusion has not yet been fully established. In addition, because they are metal-free, super porcelain/fiber crowns and bridges are particularly suitable for patients who are allergic to non-precious metals, patients who require MRI (magnetic resonance imaging) and CT examinations of the head and neck, and patients with severe wear of the opposing teeth.
