| Research Abstract |
Effects of ultraviolet (UV) irradiation on bonding properties of hard adhesive prosthetic materials such as thermosetting polymers were examined using an UV sterilization cabinet. UV-C irradiation was not effective comparing UV-B. Regarding polyamide denture base materials, bonding properties were improved after UV irradiation, moreover bonding properties enhanced with combination of UV irradiation and sandblasting.
Based on these data, an experimental UV irradiation devise was prepared using 3 UV-B lamps. Bonding strength of fiberposts using a thermosetting polymer increased after a short irradiation period comparing the UV sterilization cabinet.This eperimental UV irradiation devise is expected to improve bonding properties of other hard adhesive prosthetic materials.
