Evaluation of Bone Regeneration Efficacy in a Rabbit Model of Femoral Condyles Defect by Polyphenols-Containing Bone Filler

Abstract

[EN] The purpose of this study was to evaluate the local biological effects and bone regeneration efficacy of a polyphenols-enriched ceramic bone filler. To this end, a test article (NBR_Purple) a biphasic phosphate ceramic plus polyphenols from grape pomace and the same material without polypohenols (NBR_White), were implanted in the medial condyle of the femur bone of rabbits for 56 days. A control article of clinical use (Ostim ®), was implanted as the first control condition. There was a second control by performing the same defect at the same location but without any implanted material (void condition). Histological examination at the end of the test period shows statistically significant improvement of bone regeneration by the polyphenolenriched material over the same material without polyphenols, supporting literature data on the involvement of polyphenol molecules in bone regeneration pathways.
