Implication

Randomized trial demonstrates dual antibacterial and osteogenic effects in a hydrogel for peri-implantitis, suggesting a minimally invasive treatment option.

Key Points

This study aims to develop a charge-complementary hydrogel to provide simultaneous antibacterial treatment and promote bone regeneration in peri-implantitis.
Hydrogel was synthesized using anionic hyaluronic acid, cationic ε-poly-L-lysine, and BMP-2.
In vitro tests included cytocompatibility with rat bone marrow mesenchymal stem cells and antibacterial activity against Staphylococcus aureus and Escherichia coli.
Physicochemical properties were assessed using FTIR, SEM, rheological tests, and degradation behavior analyses.
BMP-2@HA/ε-PL hydrogel demonstrated favorable cytocompatibility and enhanced osteogenic differentiation of BMSCs.
The hydrogel exhibited robust antibacterial activity against both Staphylococcus aureus and Escherichia coli.
BMP-2 incorporation optimized the properties of the hydrogel with a densely packed network and higher compressive strength.
