Description
Summary:	Dentures are prosthetic devices built to imitate the function of natural teeth and are commonly produced from materials, such as metal, porcelain, and acrylic resin. Although those made from porcelain have good strength, their manufacture requires high skill and accuracy, which results in high selling price. This has led to the development of inexpensive natural biomaterials, as a suitable replacement in the dentistry field. Therefore, this study aims to explore the use of biocomposite (Bovine Hydroxyapatite (BHA)/Agave Cantula fiber/shellac) as a dental material. The mixture of BHA/Agave Cantula fiber was in various ratios, namely, 100/0, 90/10, 80/20, and 70/30 (%wt), where shellac was used as a binder at a proportion of 10% wt. The specimens were compacted at 20 bar for 10 min, and then sintered at 200°C for 2 h. The results of the FTIR test showed that the functional groups were hydroxyl, carbonate, phosphate, and methylene. Moreover, the results of the Vickers hardness test and density rate were recorded as the highest at the 30:70% variation, at (124.03 HVN) and (1,661 g/cm 3 ), respectively. These results showed that biocomposite has the potential to be used as a dental material after further development.
