Abstract
Rapid bone regeneration is crucial for restoring alveolar bone and oral functions following periodontal diseases. However, the development of effective biomedical materials for this purpose remains insufficient. While bone autografts can enhance bone regeneration, they are invasive to healthy areas. Specifically, for alveolar bone regeneration, the implanted material must possess adequate mechanical strength. Moreover, local administration is preferred for older adults, who are a primary target population, to maintain their quality of life. We developed a silica-substituted carbonate apatite (CO3Ap-silica) block as newly bone substitute with a bone growth factor, featuring the major inorganic component of mature bone to enhance bone regeneration. CO3Ap-silica block stimulated the bone remodeling process at the implantation site and demonstrated significantly better bone regeneration compared to currently used carbonate apatite substitutes. Therefore, this new material is expected to advance technologies for restoring occlusal function after periodontal disease.

Abstract
Silica is not only a biocompatible trace element but also an essential element for bone formation and metabolism. Therefore, it is often doped into bioceramics such as calcium phosphate and calcium carbonate for enhancing biomaterial ability. Heretofore, organic silica materials are employed as silica sources, but the residual organic matter is a significant drawback in biomaterial applications. Therefore, in this study, we introduce a one-pot inorganic synthesis method for the formation of silica-doped octacalcium phosphate (OCP) using Na2SiO3 as the silica source. Silica was intercalated into the OCP unit lattice, replacing its hydrous layer structure, and then a layer-by-layer structure of apatite and silica was formed. Furthermore, by immersing the fabricated silica-doped OCP into suitable solutions, both silica-doped hydroxyapatite and carbonate apatite were fabricated through a one-step inorganic processes. We introduced a one-pot synthesis method for silica doping of calcium phosphate. Silica easily incorporated into OCP interlayer optimizing Na2SiO3 concentrations.![]()
