M a t e r i a l s a n d m e t h o d s Sixrabbitsreceived24cylindricaldentalimplantsandwereplacedintwo groups (n = 3 per group): control group, with smooth surfaces; and test group, with the SLA surface treated with TiO2 microparticles. All of the animals were sacrificed after four weeks. Half of the implants (one per animalfrom each group)were usedtotest removaltorquevalues and half of them were used for the histological analysis.

C o n c l u s i o n Results indicate that blasting implant surfaces with TiO2 particles is an appropriate treatment option, with minimal risk of contamination by residual debris from the procedure.
