Abstract
Bioactive glasses (BGs) have been successfully used for several years as bone graft substitutes to fill defects and augment bone structures in orthopedic and dental procedures. Despite recent advances in the fabrication of reliable 3D scaffolds based on BG, the reproducibility of fabrication has only been marginally addressed and remains a challenge for their application. Recent studies have shown that BGs can react with moisture and atmospheric CO2 to form carbonates, affecting the properties and structure of the final product. In this study, factors that can affect the sintering behavior of BG powders were identified and investigated. A statistical analysis was then performed to optimize the BG sintering process, which revealed the possibility of obtaining BG scaffolds with reproducible density by acting on controllable factors such as aging and drying. In practice, this can be achieved by controlling the atmosphere during processing, handling, and storage of the material.
