Because she had a very large space with 4 missing teeth in her lower jaw. She was completely unable to eat on that side of her mouth. A removable prosthesis was out of the question, she wanted something permanent. We placed 2 implants in the space and fabricated a 4-unit porcelain bridge. The bridge is extremely strong, non-removable, and should last her the rest of her life. We accomplished this with local anesthesia only and her downtime was minimal – she was back to work the following day.
