Paragraph starter
The fabrication of porous hydroxyapatite (HA) for bone grafting applications is highly sensitive to processing parameters. Research by Priwintoko et al. (2023) highlights the critical role of sintering temperature and polyvinyl alcohol (PVA) binder composition in achieving desired porosity and pore interconnectivity via the sponge replication method. Their findings suggest that careful optimization of these factors is essential for producing HA scaffolds that meet international standards like ISO 13379:2015, thereby ensuring efficacy in bone regeneration.
