Biofilm formation around SRV-CHX-coated abutments. (a) Biofilm formation after 12 days of abutment passages. SRV-placebo and SRV-CHX-coated abutments 1, 2, and 3; (b) quantitative analysis of biofilm formation around SRV-CHX-coated abutments. The data are presented as a percentage and compared to the SRV-placebo (100%). āˆ—Significantly lower than the value for SRV-placebo ().
