다국어 초록 (Multilingual Abstract)

The introduction of several thermoplastic polymers was intended to overcome the disadvantages of methacrylate denture base resins. Existing dentures often require denture base relines to improve the fit against the tissue bearing mucosa because of gradual changes of underlying bone structure. Chair-side reline that used autopolymerizing acrylic resin is not only convenient but inexpensive means to improve the fit and function of denture bases. However, it is not known whether the differences in chemical composition of resin surface primers affect the bonding strengths between chair-side reline resin and thermoplastic denture base resin.
This study evaluated two kinds of primers(exclusive primer recommended by manufacture of thermoplastic resin and primer supplied with chair-side reline resin) to determined their effect on the bond strengths of a chair-side reline resin to two different thermoplastic denture base resins(polycarbonate and polyacetal resin) by use of a three-point transverse flexural strength test.
In both polycarbonate and polyacetal resin, each exclusive resin surface primer resulted in higher bond strength than chair-side reline resin primer(p<0.05). Bond strengths of polycarbonate with chair-side reline resin were higher than those of polyacetal resin, despite the type of resin surface primer(p<0.05).
