Although implants are the solution to many problems, the need for traditional Prosthetics will never cease to exist. The science of Prosthetics includes both fixed and removable restorations.
Fixed Prosthetics includes crowns, bridges, porcelain veneers, inlays, onlays and overlays. Materials used vary from metal alloys to ceramic materials, zirconium, etc.
Removable restorations include dentures and partial dentures, for cases of total and partial teeth loss respectively.
In any case, the ultimate goal is to restore the aesthetics and function of the oral system.
