Abstract
Experimental fiber-reinforced resin splint materials were prepared, and the fluoride release and their mechanical properties were evaluated. Methacryloyl fluoride-methylmethacrylate copolymer (PMF)was incorporated into the resin splint as the fluoride releasable source, The results were as follows:
1) The transverse strength and elastic modulus of the resin splint did not change after being imersed in water for two weeks.
2) The amounts of fluoride measured were higher on the first day and they gradually showed a decrease for 3 weeks. The amount of fluoride released was dependent on the type and amount of PMF.
3) The stickiness of the resin splint had a much lower adhesive strength than that of commerciallyavailable resin composite.
4) The resin splint showed a higher bond strength to the etched enamel (approximately 18 MPa) with cohesive fracture of the bonding agent and/or resin splint.
5) The resin splint showed a lower hardness than the resin composite.
6) The abrason loss of the resin splint with the fissure bar instrument was greater than that of the resin composite.
