摘要：
A glass material of the invention contains SiO.sub.2, MgO, Al.sub.2 O.sub.3, and TiO.sub.2 as main components in amounts of 40-65% by weight of SiO.sub.2, 9-30% by weight of MgO, 8-31% by weight of Al.sub.2 O.sub.3, and 6-15% by weight of TiO.sub.2, and satisfies expression I: {100-(A+S+T)}/S.gtoreq.0.340 wherein A, S and T are contents in % by weight of Al.sub.2 O.sub.3, SiO.sub.2, and TiO.sub.2, respectively, and Expression II: (S+M)/4>100-(S+M+A+T) wherein M is a content in % by weight of MgO, and is substantially free of fluorine. It is used in the preparation of a living tissue replacement or orthodontic part. A living tissue replacement and orthodontic part which experience a minimal loss of material properties in a deleterious environment as in the oral cavity and should have a complex shape as in the case of a dental crown repair, high strength and aesthetic appearance can be briefly prepared in a safe manner without using a special manufacturing apparatus.
