How can the retention of a Maryland bridge be increased?

Incorporating mesh work in the wax pattern enhances the retention of a Maryland bridge effectively. This technique involves creating a framework within the resin's structure, which helps to increase the surface area available for adhesive bonding to the underlying tooth structure. The mesh work provides mechanical interlocking, thus improving the overall retention of the bridge by ensuring that the adhesive has a strong surface to adhere to, making it less likely to debond over time.

Using only adhesive, while it can help in bonding, does not provide the added mechanical retention that mesh work offers. Thicker metal may improve some aspects of strength but does not necessarily contribute to retention in terms of bonding surface area. Reducing the size of the bridge could negatively affect its strength and stability without significantly improving retention. Therefore, incorporating mesh work is a strategic approach to effectively enhance the retention of a Maryland bridge.
