Provided are a hard tissue regeneration material and a hard tissue regeneration method that are excellent in hard tissue regeneration ability, extremely effectively promote remineralization of tooth enamel, and are excellent in protection and aesthetics. The hard tissue regeneration material of the present invention is obtained by, for example, immersing a base material on which a biocompatible ceramic film is formed in a solvent that does not dissolve the biocompatible ceramics but dissolves at least a part of the base material. It is a biocompatible ceramic film obtained by dissolving or separating a substrate, and has flexibility and flexibility. Further, the hard tissue regeneration method of the present invention is a method of sticking or winding the hard tissue regeneration material of the present invention around a hard tissue defect site.硬組織再生能に優れ、歯牙エナメル質の再石灰化を極めて効果的に促進し、しかも保護性・審美性にも優れる硬組織再生材料及び硬組織再生方法を提供する。この発明の硬組織再生材料は、例えば、生体親和性セラミックス膜が成膜された基材を、前記生体親和性セラミックスを溶解せず、前記基材の少なくとも一部を溶解する溶媒に浸漬して基材を溶解又は分離して得られる生体親和性セラミックス膜であり、可撓性及び柔軟性を備えている。また、この発明の硬組織再生方法は、この発明の硬組織再生材料を硬組織欠損部位に貼付け又は巻きつける方法である。
