Abstract

To date, the need for patients in orthopedic dental treatment of congenital and acquired defects and deformities of the maxillofacial region is still high. Today, digital technologies are widely used to create facial epithets, including additive 3D printing technologies with new construction materials. However, until recently, the range of prosthetic care products was limited only to traditional dental prostheses for the oral cavity, which prompted the development of special hygiene products. Aim: to determine the adhesion of the pathogenic microflora of the oral cavity to the structural material used in the production technology of facial prostheses by volumetric printing, after treatment with hygienic means for their care.
Materials and methods.
the evaluation of the microbiological effectiveness of the proposed compositions of hygiene products was carried out in an experiment. The adhesion of strains of microorganisms Escherichia coli, Staphylococcus aureus, Candida albicans, Streptococcus mutans to structural material samples made on a 3D printer by volumetric printing without treatment with cleansing foam and spray and after treatment for two minutes was evaluated.
Results.
The results of the study showed that all the studied conditionally pathogenic microorganisms have low adhesive activity in relation to the structural material for facial epitheses made by 3D volumetric printing, and after processing the samples with hygienic foam, a zero adhesion index was noted (p<0.05). When treating the surface of the samples with an indelible hygienic spray for 2 minutes, the adhesion of S. mutans to the material decreased by 25%, S. aureus — by 8.91%, C. albicans — by 100%, and the adhesion of E. coli increased by 26.6% compared to samples without additional treatment.
Conclusions.
The studied hygiene products in the form of foam and spray for the care of facial epitheses made by 3D volumetric printing are effective against opportunistic microorganisms Escherichia coli, Staphylococcus aureus, Candida albicans and Streptococcus mutans significantly reduce their adhesion index to the surface of the material.
