Er:YAG laser biofilm removal from zero-gap periodontal/peri-implant model system mimicking clinical attachment loss.

ABSTRACT:

Significance

Here, we present a photoacoustic method to remove biofilms from periodontal and peri-implant-constrained geometries.

Aim

We aim to remove biofilms from narrow periodontal and peri-implant model systems with the application of Er:YAG ultrashort laser pulses.

Approach

Construction of zero-gap model system from PDMS and titanium, growth of biofilms on titanium surfaces, and removal of biofilms with Er:YAG USP, 20 mJ, 15 Hz, and 10 s were performed.

Results

The results suggest that geometry, the vertical position of the laser fiber tip, and the evolution of the primary cavitation bubble significantly affect cleaning effectiveness. Cleaning was higher in the wedge part of the model system. In the zero-gap part of the model system, biofilm cleaning effec
