What is a significant disadvantage of a resin bonded denture such as a Maryland Bridge?

A significant disadvantage of a resin bonded denture, such as a Maryland Bridge, is the potential for debonding. This occurs when the bond between the resin and the tooth structure or the metal framework fails. Factors that can contribute to debonding include the stresses placed on the bridge during chewing, the condition of the tooth surface to which it is bonded, and oral hygiene practices. If the bond is compromised, it can lead to the bridge becoming loose or completely dislodged, necessitating repairs or replacement.

While other options, such as color matching might pose some challenges (especially in achieving a completely natural appearance), they do not typically compromise the functionality of the bridge as significantly as debonding. Similarly, while high costs and long-term durability may be considerations, the risk of debonding is often more immediate and critical in the daily use of a Maryland Bridge. Therefore, debonding stands out as a prominent disadvantage in this context.
