Finish Lines in Fixed Partial Dentures

Abstract

Treatment with tooth-supported fixed dental prostheses (FDPs) is still one of the most common ways to replace damaged teeth, and it has a high long-term clinical success rate. Tooth abutments can be prepared to receive fixed dental prostheses with different types of finish lines.

In any tooth preparation, the finish line design is critical because it affects not only the sealing difference but also the appearance of the tooth,disparity in seating. aesthetics, periodontal fitness and  biological width.
