In more than 90% of cases the implant osseointegration in the alveolar bone is reported to be successful, but implant placement may also be accompanied by some complications that can occur during the procedure of dental implant placement as well as in the postoperative period. The article presents the results of the study of bio-film-forming properties of clinical strains of gram-positive microorganisms, pathogens of infectious-inflammatory complications of odontoplasty. Biofilm-forming properties were investigated on 145 clinical strains of conditionally pathogenic microorganisms (Staphylococcus aureus, Staphylococcus epidermidis, Staphylococcus warneri, Streptococcus sunguinis та Kocuria kristinae), isolated from patients with infectious odonto-implant related complications, using the spectrophotometric method (MtP-test «microtiter plate test», by G.D. Christensen). Clinical strains of S. aureus, S. epidermidis and S. sanguinis have been established to have high biofilm-forming properties, and K. kristinae – obtained medium ones. S. warneri had the lowest biofilm formation.
