Abstract Objectives This study aimed to improve the performance and mode of administration a glass-reinforced hydroxyapatite synthetic bone substitute, Bonelike by Biosckin® (BL®), association with dextrin-based hydrogel, DEXGEL, achieve an injectable moldable device named DEXGEL Bone. Methods Twelve participants requiring pre-molar tooth extraction implant placement were enrolled in this study. BL® granules (250–500 µm) administered 6 randomized whereas other received After months, biopsy...

Abstract A local drug delivery system that attempts to find a suitable balance between antimicrobial and regenerative actions was developed for osteomyelitis treatment (OM). This combines the angiogenic immunomodulatory peptide LLKKK18 (LL18) vancomycin hydrochloride (VH), loaded into an injectable oxidized dextrin (ODEX)‐based hydrogel (HG). In vitro cytotoxicity analyzed in MC3T3‐E1 pre‐osteoblasts erythrocytes. The kinetics of LL18 release studied. Antimicrobial activity assessed against...

In this work, an expedite synthesis was developed for a self-assembled micelle carrier the antimicrobial peptide LL18. Covalent one-pot functionalization of dextrin with succinylated vitamin D3 and succinic anhydride produced amphiphilic material that undergoes self-assembly into micelles in aqueous medium. Succinylated dextrin-vitamin were efficiently loaded LL18 by electrostatic hydrophobic interactions. Remarkably, LL18-loaded formulation dramatically improves antibacterial activity free against

Regeneration of severe bone defects remains a challenge. A formulation synthetic glass-reinforced hydroxyapatite substitute, Bonelike® Poro (BL®P), 250 - 500 µm-diameter, with dextrin-based hydrogel (HG), further loaded human dental pulp stem cells (hDPSCs) osteogenic differentiation ability, was tested for the management critical-sized in an ovine model. Morphology, calcium release, and mechanical strength HG + BL®P were analyzed. Then, BL®P, 106 hDPSCs-loaded implanted 14 mm-diameter...
