Abstract
Abstract A method comprises the steps of applying a gallium alloy in liquid form to the surface of an adherend metallic portion, and forming an alloy layer containing Ga, Sn, In or Zn on the surface of the adherend metallic portion, whereby an excellent adhesive surface having stability and water resistance can be formed on an adherend metallic portion to be contacted to cement or adhesive resin, by a very easy process without the need to use any special apparatus or instruments during the operation of adhesively bonding a resin portion of a denture base to a metallic portion or a dentine to a restorative metallic material such as an inlay, a crown or the like.
