OBJECTIVES: The aim of this study was to evaluate the in vitro surface morphology alteration of three different implants undergone to a decontamination technique by using the Erbium – Yag laser. METHODS: The three trial groups were composed of twenty machined implants, twenty sandblasted and etched implants , and twenty TPS implants, sixty in all. Every group was divided in two subgroups composed of ten implants: a sample and a control one. The laser probe used was the FC90DE LIGHT, featuring an 80° bending radius with a twenty microseconds drive rate, and emission pulsated at ten Hz speed and 30 MJ power. The probe worked on implants with a 45° angle of incidence to the axial surfaces of the implant threads, developing apex-crown motions that lasted sixteen seconds. The evaluation of implant surfaces was made using a S.E.M. device , taking three size pictures (1000x, 6000x,11000x) and comparing the sample group with the control one. The data were made statistically significant using the student test (p<0,05). RESULTS: Results showed no surface alterations on the sample group implants . CONCLUSION: These preliminary results may suggest the use of Erbium – Yag laser as one of the standard peri-implant instrumentation to treat the implant surfaces affected by peri-implant diseases.
