a comprehensive review of gelma-nha 3d printing bone scaffolds

Tissue engineering scaffolds are an effective method for treating bone defects, and their structure and function are essential for bone regeneration. gelatin methacrylate (gelma) and nano hydroxyapatite (nha) are two materials that have shown great promise in creating 3d printed scaffolds for bone tissue engineering. the integration of these two materials has the potential to revolutionize the field of bone tissue engineering, as it allows the creation of scaffolds that mimic the structure and composition of natural bone. in this article, we will examine the effect of gelma-nha 3d printing scaffold in bone tissue engineering.
