Posterior restorations in dentistry are often done using porcelain fused to metal (PFM) restorations, as aesthetics is not a primary concern in this area of the mouth. Noble alloys are semiprecious metals containing more than 25% noble metals such as gold, platinum and palladium, which makes them more hypoallergenic than their base or high-noble counterparts. The benefit of using noble alloys for posterior restoration is that they provide an excellent level of performance while also being cost-effective.
