The Effect of Green Tea Polyphenol (EGCG) on Orthodontic Micro-Implant Stability: An experimental study

Abstract

Background Increasing the orthodontic micro-implant stability and enhancing bone response around it, is a fundamental objective of successful therapy. Materials and Methods Thirty orthodontic micro-implants, 1.3 mm in width and 5 mm in length (Dentos, AbsoAnchor, South Korea), were used with three implants were inserted in the right tibias of ten New Zealand rabbits, the rabbits categories into two groups, fve each. The primary stability was measured once the implant inserted, using Periotest. The experimental group fed (0.5% wt/vol/day) Green Tea, using the loading technique, for four weeks interval. At the end of the experimental period, the rabbits were sacrifced, and the secondary stability measurement was taken. Results Using paired t-test, the results showed a signifcant increase in secondary stability for the experimental group after four weeks experimental period when compared with the primary one. While the control group showed a non-signifcant increase in the secondary stability compared with the primary one. Conclusion This study concluded that the Green Tea could enhance bone response around orthodontic micro-implant within four weeks healing period and consequently increase the stability of orthodontic micro-implant
