Metal restorations have greater compressive and tensile strength than other materials, with minimal wear of the surrounding teeth. They’re also ideal for longevity, reliability and long-term durability, protecting the remaining tooth structure with excellent marginal integrity. Our metal restorations are certified by US IdentAlloy® for biocompatibility.
Type IV alloys suit single crowns to large bridges and implant superstructures and Type II alloys suit short-span bridges, single crowns, inlays, onlays and partial crowns.
