patient individually, the so-called personalized or patient-
specific solution. With regard to the bone scaffold creation,
which is an integral part of the bone tissue substituent,
primarily serving to provide mechanical support to the
weakly consolidated granular consistency of the bone graft,
personalization comprehends multilateral adaptation of a
bone scaffold design: its geometry should be shaped in
accordance with the patient anatomy and implantation
conditions whereas mechanical and biochemical features of
the scaffold structure should be harmonized to the corre-
sponding patient’s specifics. Typical cases when the use of
personalized bone scaffold (PBS) is indicated are related to
