This study was carried out to obtain the exclusive bonding agent for the trial relining material made of cyclophosphazene monomer [4PN-(TF)2-(EMA)6]. Namely, adhesive strength was measured on tensile test under various composition formulae and treatment times.
Relining specimens after bonding tereatment, performed to place on a base resin plate (size 15×20×3.5mm), contact with a circle of 3mm diameter. The trial exclusive bonding agent wassingled out obtained good results. And a commercial bonding agent were used for their own.
Adhesive strength were measured and compared between the commercial relining materials and the trial, and the following results were obtained:
1. Base on adhesive strength, a trial exclusive bonding agent was thought to have a good result at the composition mixted of MMA: CH2Cl2:HEMA=10:50:40 (as wt%).
2. For the best treatment time, base on adhesive strength, about 60 seconds were thought to be sufficient time until the relining after brushed the trial bonding agent on a plate.
3. The best standing time until visible light curing was 60 seconds.
When the trial relining was performed under conditions described in sections 1, 2 and 3, adhesion strength was greater than that of the commercial material, suggesting that the trial bonding agentis potent of clinical application. The purpose of this study was therefore fulfilled.
