| Outline of Final Research Achievements |
There has been a great deal of recent public interest in allergic reactions to the metals used for dental applications, and there is concern about biomedical use of metallic materials. Pure titanium has excellent biocompatibility, and shows reduced possibility of metal allergy. Due to the low thermal conductivity and high chemical reactivity, the machining of pure titanium is very difficult. Therefore, pure titanium is not widely used in dental materials. In this study, a polyurea resin-bonded mounted wheel was developed for polishing of pure titanium. Using this mounted wheel, polishing of pure titanium was achieved over a short time compared with four commercially mounted wheels designed for use by dentists and dental technicians.
