Special Issue Information Dear Colleagues, Biocompatible inorganic materials are most often used for the compensation and treatment of bone defects. Such materials are obtained using technologies of ceramics, cements, glasses, and glass–ceramics. Systems of oxides which are inert to the body's environment or oxide systems of metal and elements present in bone tissue are considered for the creation of biocompatible inorganic materials. The phase composition of inorganic materials is a reliable tool for managing the key properties of composites in these systems. Biocompatible, inert, and nonresorbable materials are needed to replace lost bone tissue for a long period of time. Biocompatible biodegradable materials are necessary for the development of modern regenerative methods of treatment involving the promotion of the self-healing of bone tissue. The development of advanced inorganic materials for medical purposes involves research related to the creation of powder precursors for bioceramics, bio-cement stone, and bioactive-glass-based composites. Such a characteristic of inorganic biomaterials as osteoconductivity involves the creation of a material not only of an acceptable chemical and phase composition, but with a given porosity. Methods for creating a porous structure in inorganic materials for bone tissue engineering are in constant development. Evaluation of the applicability of new materials in medicine involves the use of in vitro and in vivo tests. Thus, this Special Issue will be devoted to various aspects of the creation of new materials designed to compensate and treat bone defects, including the synthesis and preparation of powder systems; the creation of dense and porous ceramic, cement, glass, and glass–ceramic materials; as well as the assessment of the biocompatibility and bioactivity of these materials and their ability to support bone regeneration.
