The present invention relates to a dental cement composition including a tricalcium silicate powder and a dicalcium silicate powder, a method for preparation of an implant for regenerating a tissue including a tricalcium silicate powder and a dicalcium silicate powder, and a kit for preparing a dental cement including a tricalcium silicate powder and a dicalcium silicate powder.

Macroporous cement compositions, methods of making the same, and methods of using the same, are described.

The present invention relates to a dental composition including cement and a non-aqueous liquid, wherein the cement includes a first domain including alite, a second domain including belite, and a matrix located between one or more selected from the group consisting of the first domain and the second domain and configured to include silicon (Si)-atom-doped tricalcium aluminate (3CaO.Al.sub.2O.sub.3). A dental hydraulic composition according to the present invention is a single ointment-type composition, and is thus easy to use and exhibits a good aesthetic appearance, high curability and high biocompatibility.

The present disclosure provides a root-canal sealer composition including cement and a hygroscopic liquid, in which the cement includes tricalcium silicate (3CaO.Math.SiO.sub.2) in which an aluminum atom (Al) is solid-soluted (Al solid-soluted C3S), dicalcium silicate (2CaO.Math.SiO.sub.2) in which an aluminum atom (Al) is solid-soluted (Al solid-soluted C2S), and tricalcium aluminate (3CaO.Math.Al.sub.2O.sub.3) in which a silicon atom (Si) is solid-soluted (Si solid-soluted C3A), the tricalcium aluminate being disposed between at least one selected from the group consisting of the Al solid-soluted C3S and the Al solid-soluted C2S. When the cement including aluminum solid-soluted tricalcium silicate, aluminum solid-soluted dicalcium silicate, and silicon solid-soluted tricalcium aluminate is prepared and used for a root-canal sealer composition, a curing time is reduced and compressive strength is increased. Also, the root-canal sealer composition is effective at ensuring a sufficient working time, thereby improving workability and storage stability.

The present invention relates to a rapid-setting hydraulic binder composition and, more specifically, to a hydraulic binder composition, which contains tricalcium aluminate (C3A) and dodecacalcium heptaaluminate (C12A7), and thus is rapidly set, has an easily adjustable setting time, and is bio-friendly.

A biocompatible composite material for controlled release is disclosed, comprising a biocompatible metal oxide structure with a loaded network of pores. The pore network of the biocompatible composite material is filled with a uniformly distributed biologically active micellizing amphiphilic molecule, the size of these pores ranging from about 0.5 to about 100 nanometers. The material is characterized in that when exposed to phosphate-buffered saline (PBS), the controlled release of the active amphiphilic molecule is predominantly diffusion-driven over time.
