Key Quotes:

“Think about how that patient is going to be able to maintain those restorations, those prostheses that you’re putting in your patient’s mice.” – Dr. Gerry McKenna


“So certainly I would be advocating that where possible we think about treatment approaches, which are centered around the shortened dental arch that’s healing a functional dentition. Rather than thinking every missing two for this patient must be replaced, particularly if the option is a removable partial denture.” – Dr. Gerry McKenna
