Abstract

良好な鋳造性を有し, 生体適合性に優れた歯科用チタン合金を開発することを目指した.Tiと同等の生体適合性を持ち, Tiと全率固溶するZr, およびZrに対するα安定化元素としての効果が期待できるSnを構成元素とするTi-Zr-Sn系3元合金を試作した.試作した合金について, 鋳造性の評価, 鋳巣の観察, 引張強さの測定, ならびにX線回折実験を行った.その結果, 歯科鋳造用として期待できる鋳造性と純Tiの2倍以上の引張強さを持つTi-Zr-Sn合金が見出された.

The aim of the present research was to develop a new dental titanium alloy with good castability and biocompatibility. Since Zr is known to have good biocompatibility and form a continuous solid solution with Ti, we selected Zr as an additive element. Also, Sn is expected to have the stabilizing effect of the alpha-phase. Based on this information, we prepared ternary Ti-Zr-Sn alloys with different compositions. Castability, porosity, tensile strength, and crystal structure of the experimental Ti-Zr-Sn alloys were examined. The results showed that the Ti-Zr-Sn alloys possess excellent castability and tensile strength exceeding twice that of pure Ti. This evidence suggests that Ti-Zr-Sn alloys can be used as dental casting alloys.
