Dental metal primers are used to create a strong bond between dental alloys and resin or acrylic materials. These primers prepare the metal surface for bonding, and should help create both a chemical and a mechanical bond to connect the two materials. These primers are useful for a range of fixed and removable restorative options, as well as for orthodontics and some implant cases. Be sure the primer you choose is compatible with the alloys and resins you will be using.
