Muller de Van's principle of preservation "Perpectual Preservation of what remains is more important than meticulous replacement of what is missing" holds true to all aspects of dentistry. The goal of modern dentistry is to restore the patient to normal Contour, function, comfort, esthetics, speech, and health, whether by removing caries from a tooth or replacing several teeth. However, the more teeth a patient is missing, the more challenging this task becomes. As a result of continued research, diagnostic tools, treatment planning, implant designs, materials, and techniques, predictable success is now a reality for the rehabilitation of many challenging clinical situations.
