Which material is recommended for the fabrication of Maryland bridges?

The fabrication of Maryland bridges, which are a type of adhesive bridge typically used in dentistry for replacing missing teeth, requires materials that offer significant strength and durability. Choosing extra hard materials is essential because they can withstand the forces of chewing and prevent premature wear or breakage, ensuring the longevity of the bridge in the oral cavity.

Extra hard materials are specifically formulated to provide enhanced strength, making them suitable for the demands of functional usage in dental applications. These materials often include high-strength alloys or ceramics, which are designed to offer both aesthetic qualities and the durability necessary for restorations in a dynamic environment like the mouth.

While composite resins may have aesthetic advantages and can be used in some contexts, they may not provide the same level of strength necessary for a Maryland bridge, especially in high-load areas. Single phase and multi-phase materials could also lack the specific mechanical properties needed for such applications, making them less suitable compared to materials classified as extra hard.
