NuMat Medtech

NuMat Medtech has focused on 2 bioactive coatings, based on small molecules of natural origin, with potential applications in dental and orthopedic markets. The coatings developed by NuMat are trying to solve the main problems with current commercial osteoimplants, including poor osteointegration and high risk of infection.



Bioactive surface modified with flavonoids with osteogenic, osteoinductive, anti-inflammatory, anti-fibrotic properties and significant reduction of bacteria colonization

NM_973 is a coating based on flavonoids, small polyphenolic molecules derived from plants with antioxidant, anti-inflammatory and antibacterial properties. They are present in the daily human diet and their intake has been related to the prevention of cancer, cardiovascular and neurological diseases.

Metal surfaces coated with the flavonoid can promote both soft and hard tissue integration, which is of high interest in order to avoid peri-implantitis occurrence in dental implants, thus decreasing implant loss risks.
