Objectives: The aim of this study was to evaluate the performance of a 10 wt% platelet-rich plasma (PRP) additive composite with calcium phosphate cement (CPC) in vitro and in vivo.
Methods: The in vitro testing of modulus, the apatite conversion rate, morphology, cell and alkaline phosphatase (ALP) activities, and in vivo testing of histological examinations between two groups of 10 wt% PRP/CPC and CPC were characterised and compared.
Results: Although the crystallite morphologies showed a retarded effect in the PRP/CPC group in vitro, the modulus results showed that the 10 wt% PRP/CPC group had a significant reduction in strength but had no significant changes in the relative conversion ratio of the apatite phase with CPC only. The osteogenic evaluation of ALP expression was significantly increased by the PRP additives group with stem cells (D1) cultured for different periods (2-32 days). Our histological examinations showed that greater remodelling and the phenomenon of isolated/detached CPC particles were significantly observed at 9 weeks after implantation when the 10 wt% PRP/CPC composite was used.
Conclusion: The results demonstrate that CPC may be a potential candidate as a carrier with PRP additives for bone regeneration.

This study aims to evaluate further the performance of a platelet-rich plasma (PRP) additive incorporated with calcium phosphate bone cement (CPC) in vitro to prove its efficiency as bone graft substitutes and its compatibility to be incorporated into the CPC with other techniques in clinical restoration in vivo. The growth factor release ability and the osteogenic evaluation of PRP, CPC, and PRP/CPC testing groups with 5, 10, and 15 wt.% PRP were compared in vitro.
