Purpose: Osseointegration is the structural and functional connection without fibrous tissue, between the bone and the implant surface under load. Free radicals are among the factors that affect bone healing and osseointegration. Recently, researchers have begun to show interest in the idea that implant-related complications may occur due to free radical-induced tissue damage. Hence use of a material with antioxidant properties may be a useful tool on implantology. This study is planned presuming propolis could have positive effects on osseointegration and implant stability due to its antioxidant nature, its effect accelerating the bone formation, wound healing and increasing the bone density.
Methods: Study consisted of three groups. At all groups, implants were placed on proximal metaphyseal region of the rabbit tibia. Only dental implants were placed on the Control Group. Propolis solution was applied to slots before placing the implants on Local Group and propolis was applied systemically for 28 days after implantation on Systemic Group. Resonance frequency analysis (RFA) was performed on the day implants are placed and both RFA and removal torque test were performed on the 28th day.
Results: The study was composed of 24 rabbits grouped as follows: Control (n = 8), local (n = 8), and systemic (n = 8) for application of propolis. Systemic group showed statistically lower results of RFA at baseline (p<0.05). Propolis application resulted in a significant increase in RFA in each group: local (baseline RFA, 46,8 vs RFA after Propolis 56.0; P< 0.05), systemic (baseline RFA, 44.8 vs RFA after propolis, 58.8, P< 0,05); while the control group showed no significant difference (baseline RFA, 51.5 vs RFA after waiting period, 57.8 P> 0.05). Removal torque test showed statistically significant difference between the groups (systemic group 58,7; local, 49,8 and control, 45,1; P<0.05).
Conclusion: These results suggest that the propolis may have a positive effect on implant stability, especially if administered systemically.
