| Research Abstract |
Cholesterol-bearing pullulan(CHP) nanogel is a synthetic degradable biomaterial for drug delivery with high biocompatibility. The purpose of this study was to evaluate the effects of the CHP nanogel membrane in guided bone regeneration(GBR). As a result of micro-CT analysis, new bone formation in terms of bone volume was higher in the nanogel group than in the control or collagen groups at 2 and 4 weeks. Histologically, new bone formation in CHP nanogel was prominent at 2 and 4 weeks compared with the other two groups. Notably, newly-formed bone in the CHP nanogel group was mature bone. The results of this study suggest that CHP nanogel membrane would be potentially effective as a GBR membrane.
