Maryland bridges, also known as resin-bonded bridges, are typically fabricated using materials that provide sufficient strength and durability to withstand the forces encountered in the oral environment while allowing for a conservative dental approach. The correct answer focuses on the use of extra hard materials, which are crucial for the framework of the bridge. These materials must exhibit high tensile strength and resistance to fracture in order to support the artificial tooth anchored to the abutment teeth.

Extra hard materials, which can include base metals and certain ceramic materials, ensure that the Maryland bridge maintains its integrity under normal function, such as chewing and speaking. Their hardness contributes to wear resistance, which is essential in preventing failure over time.

The other options do not fit the requirements for Maryland bridges. Single phase materials lack the necessary physical properties for this application, while multi-phase materials may not provide the rigidity required. Soft bonding materials, although useful for adhesion, would not be appropriate for the structural components of the bridge itself. Therefore, the use of extra hard materials is essential for the successful fabrication and longevity of Maryland bridges.
