Abstract:
Implants in the form of polymer scaffolds are commonly used to regenerate bone tissue after traumas or tooth extractions. However, few implant formation methods enable building polymer scaffolds allowing to reconstruct larger bone losses without immune response. Spacious, porous poly-l-lactide implants with considerable volume were obtained using the phase inversion method with the freeze-extraction variant. The calcium phosphate (CaP) coating was deposited on implant surfaces with the biomimetic method to improve the implant's osteoconductivity. The substitues morphology was characterized-porosity, size and shape of pores; mechanical properties, mass absorbability of implants before and after mineralization. The characteristics were provided with scanning electron microscopy (SEM), static compression test and hydrostatic weighing, respectively. The presence of CaPs in the entire volume of the implant was confirmed with SEM and infrared spectroscopy with Fourier transform (FTIR). The biocompatibility of scaffolds was confirmed with in vitro quantitative test and microscopic observations. The obtained results show that the implants can be used in tissue engineering as a vehicle of platelet-rich plasma to regenerate critical spongy bone losses.
