Biomaterials are artificial or natural materials that replace diseased or damaged bone tissue, recently with increasing interest in interdisciplinary approaches, including e.g. bioengineers. Such materials must be mechanically strong and not cause undesirable reactions. Due to the many factors that need to be considered, choosing the right material becomes a challenge. The relevance of the study lies in the development of a method for choosing a synthetic material based on hydroxyapatite for bone tissue restoration. Hierarchy analysis method was used and a set of five materials and their seven mechanical and biological parameters were analyzed.

Synthetic hydroxyapatite is used in biomedical engineering for its desirable mechanical properties. But not all scaffolds are biocompatible in use. The safety of implants depends on the competence of medical personnel, manufacturing technology, as well as biological, mechanical and other properties. Although there are regulatory standards for the safety of biomaterials, the assessment of their biocompatibility is a difficult task, which is associated with the properties of spacesuits, the duration of contact with tissues. The article proposes a method for assessing the safety of implants depending on various factors that form their biocompatibility.
