*3.4.3 Chitosan-HAP composite*

Another group of researchers synthesized a composite containing chitosan, HAP, and bioglass. Chitosan-HAP composite was prepared using calcium nitrate and orthophosphoric acid in SBF. The novel prepared composite bioactive glass was added to this preparation. *In vitro* bioactivity was determined for the composite and the study found that the addition of bioactive glass improved the compression strength of the material [43]. A prepared HAP-bioglass composite was developed to improve the compression strength of the composite compared to pure HAP. In this study, HAP was synthesized and combined with a varying percentage of bioglass and was pelletized. The biocomposite dental implanting material was characterized using various techniques and the study found that HAP with 10% bioglass was having increased bioactivity and compression strength (**Figure 2**) [44].
