Abstract
With a view to investigating the effect of various functional monomers on the adhesion of dental alloys, adhesive tests of dental alloys were carried out using MMA-TBB type resins with acid anhydride or carboxylic monomers.Indeed, addition of a functional monomer was effective in cases using a monomer with an acid anhydride or a carboxylic group as well as using a small amount of crosslinking agent, but durability made the difference between structure of monomers.Sandblasting of the alloy surface was broadly effective to suppress decreasing adhesive strength, but even in this case the effects of various monomers were clearly observed.Judging from the fact that acid anhydride groups of monomers were hydrolyzed during long term storage, it is believed that carboxylic groups of monomers played an important role in adhesion of dental alloys in underwater conditions.
