The most likely reason for debonding of Maryland Bridges is inadequate tooth preparation. I recommend placing grooves and/or box forms in the enamel surfaces of the abutment teeth. These retentive features, combined with a good bonding agent and a current generation resin cement, provide adequate retention for most Maryland Bridge situations Chang 1991 tooth preparation 2.

Finances were a limiting factor. The existing bridge was deemed poor and could not be used.

The non-metallic options for Maryland bridges include a variety of different ceramics, most notably those considered to be high strength, such as lithium disilicate or zirconia. Due to its very high strength and toughness, some of the best results have been attributed to zirconia. The design of the preparation and the restoration may also.
