抄録

Secondary failure in adhesion at the denture base resin and self-curing resin interface is a common problem with repaired or relined denture. It is caused by insufficient bond strength of both materials. Various organisms, bacteria, and plenty of water penetrating the denture base resin are considered to be the important factors which decrease the bond strength of both materials. The purpose of this investigation was to determine the effect of water absorbed in the denture base resin on shear bond strength and bond durability between the denture base resin and self-curing resins. In addition, effects of some chemical and mechanical etching treatments of the denture base resin surface on shear bond strength between two materials were also studied.<BR>The results were as follows:<BR>1. Bond strength and durability of water saturated denture base resin and self-curing resin were not necessarily decreased in comparison with the use of dried denture base resin.<BR>2. In case of using Unifast II, bond durability to the thoroughly dried denture base resin was markedly decreased.<BR>3. Unifast II demonstrated the highest bond strength and durability to the denture base resin treated with 50μm aluminum oxide sandblasting.<BR>4. Tokuso Rebase (Normal Set) demonstrated the highest bond durability to the denture base resin treated with methylene chloride.
