Abstract

Oral health problems, particularly tooth defects, can significantly affect people's quality of life and overall well-being. The development of titanium (Ti) dental implants has largely replaced natural tooth roots to prevent periodontal and gastrointestinal diseases. However, challenges such as postoperative bacterial infections and poor osseointegration continue to hinder progress in dental implant technology. To tackle these issues, we used hydroxypropyl trimethylammonium chloride chitosan (HACC) and gallic acid-modified gelatin (GAG) to create extracellular matrix (ECM) coatings on titanium using layer-by-layer self-assembly. GAG showed better water solubility at room temperature, being over 99.0 times more soluble than regular gelatin. In vivo and in vitro analyses of the ECM coatings revealed their antibacterial properties and their ability to promote osteogenic differentiation, resulting in over 31.5 times more calcareous deposits than Ti. This strategy shows potential for improving oral health and reducing the complications associated with dental implants in clinical settings.
