Resin-bonded Fixed Bridges Procedure Casting The pontics and retainers are fabricated with a connection as a single unit pattern. Soldering Multiunit wax patterns are cast separately.They are approximated against one another and soldered together using a different soldering alloy. Sometimes a single unit wax pattern is cast and sectioned using a saw and then soldered. Casting is preferred because it avoids galvanic corrosion. Soldered connectors are more uniform, flat and parallel because the flow of the solder alloy is easily controllable.
