Antibacterial Properties
Joanna Kolmas et al.[/center]
Reconstructive surgery is presently struggling with the problem
of infections located within implantation biomaterials. Of
course, the best antibacterial protection is antibiotic
therapy.However, oral antibiotic therapy is sometimes
ineffective, while administering
an antibiotic at the location of infection is often associated
with an unfavourable ratio of dosage efficiency and toxic
effect.Thus, the present study aims to find a new factor which
may improve antibacterial activity while also presenting low
toxicity to the human
cells. Such factors are usually implemented along with the
implant itself and may be an integral part of it.Many recent
studies have focused on inorganic factors, such as metal
nanoparticles, salts, and metal oxides. The advantages of
inorganic factors include the
ease with which they can be combined with ceramic and polymeric
biomaterials. The following review focuses on hydroxyapatites
substituted with ions with antibacterial properties. It
considers materials that have already been applied in
regenerative medicine (e.g., hydroxyapatites with silver ions)
and those that are only at the preliminary stage of research and
which could potentially be used in implantology or dentistry.We
present methods for the synthesis of modified apatites and the
antibacterial mechanisms of various ions as well as their
antibacterial efficiency.
