The aim of the present investigation was to evaluate the efficacy of an antibacterial coating of implant-abutment prosthetic junctions by real time measurement of Volatile Organic Compounds (VOCs). A total of 20 patients and 40 internal prosthetic junction implants were evaluated in the present investigation: 20 fixtures with antibacterial internal coating (Test) and 20 without treatment (Control). The VOCs measurements were evaluated at the baseline (T0) after the cover unit unscrewing, after 7 days (T1) and at 14 days (T2). No significant difference were detected at T0 (baseline), as Test and Control groups showed a VOCs max peak mean respectively of 2.15 ± 0.71 and 2.21 ± 0.69 (p > 0.05). At T1 and T2 as significant difference between the Test and Control Groups was detected (p < 0.01). At T2 the Test max peak was 2.29 ± 0.73 and the Control was 3.65 ± 0.91 (p < 0.01). The antibacterial internal coating demonstrated the capacity to prevent microbial VOCS activity at the level of the implant internal chamber and could be useful for long-term peri-implant tissue health.
