Fixed dental restoration is a permanent dental prosthesis. It is firmly fixed (attached) to patients’ prepared teeth, and will not be taken out of their mouths during the day and night. This kind of restoration is like patients’ natural teeth, offering excellent chewing and biting strength, remarkable oral hygiene, and superior aesthetics. Fixed dental prostheses include crowns and bridges, Onlays and inlays, post and core, veneers, and dental implants. It also consists of different materials like zirconia, E-max, composite resin, porcelain-fused-to-metal (PFM), full metal cast (FMC), and pure titanium. Those materials provide different effects.
