Abstract

Dental implants increase the quality of life for many patients with tooth loss, peek might replace titanium as dental implant, but its surface need to be modified in order to improve and accelerate osseointegration. To evaluate the effect of RF nitrogen plasma treatment of peek implant screws on the strength of implant-bone interface after 2 and 6 weeks after implantation in rabbit tibia bone. 6 Peek’s discs and screws had been prepared to be treated with RF nitrogen plasma. Eighteen male New Zealand rabbits tibias were chosen as implantation sites, fifty four screws were implanted in tibia bone, three screws in each tibia, the rabbits were divided into two groups of two and six weeks according to healing intervals, twenty one screws were tested for torque removal of each group of implants in each periods, and six implants of each group of implants in each periods were used for histological examination and histomorphometric analysis. There was significant increase in mean values of torque removal for the nitrogen plasma treated implants in comparison with untreated peek implant for both periods of two and six weeks. Plasma treatment of peek implant by RF device had remarkable influence in increasing the osseointegration than untreated peek implant.
