title: Bucco-lingual "dimple" technique for removing full-crown and cast-metal restorations.
abstract: Many longitudinal studies of the longevity of full-crown and cast-metal restorations have been made. Dentists and dental team members marvel at the crown or bridge that has been in place and functioning for 30 or 40 years in a mature or elderly patient. Dental insurance company statistics and clinical records seem to indicate, however, that the average life span of a crown is closer to seven or eight years. How do you respond to the patient who asks, "Doctor, how long will this crown/bridge last?" Whatever your answer, it is realistic to expect that a newly inserted crown or fixed bridge will require replacement at some point in the patient's lifetime.
