Osseointegration used in relation to titanium metallic implants, the idea now applies to all biomaterials that can osseointegrate in facial bone, such as ceramics which used as bone substitutes. Objective: to compare the decontamination of dental implants using chlorhexidin and ozonated water contact time (1 & 3 min.) each prior to implantation in rabbits' tibial bone. Patients and methods: Twenty eight healthy New Zealand white rabbits weighing 2.5-3 kg were used for this study and divided equally into two groups, then each group subdivided into two subgroup each of seven. Dental implants decontaminated by chlorhexidine 2% and ozonated water. All animals have been sacrificed 8 weeks post implantation. The operated tibia have been harvested and preserved in formalin 10%.  New bone and the osteoid matrix content around the dental implants have been evaluated histologically. Results: All animals of the experiment stayed a life till the end of the experiment with no complications what so ever except some members in groups A1, B1 and B2 shows sinus tracts oozing pus at the surgical site. The acute abcess (A.A) in rabbit tibial bone showed a significant decrease in groups A2, B1 and B2 in comparison with group A1. The lowest decrease was observed in groups A2 and B1.The subacute abcess (SA.A) showed a significant increase in rabbit bone of group B1 when compared with group A1. The non-abcess (N.A) revealed a significant increase in rabbit bones of groups A2 and B2 comparatively with those of group A1, however N.O.M in rabbit bone of  group B1 showed insignificant statistical change when matched with group A1. Conclusion: Decontamination of already contaminated dental implant with human saliva prior to implantation using chlorohxidine 2% for three minutes give decent and proper result on the surrounding bony tissues than using ozonated water from ozone generator device (output 400 mg/hour ) when used for the same exact  time.
