The benefits of TiN and DLC biofunctional dental implant coatings

Increase Dental Implant Longevity with Bio-functional TiN & DLC Coatings” is an expert article featured in the latest issue of Medical Device Briefs. Written by VaporTech® R&D scientist Ganesh Kamath, Ph.D., this informative piece about bio-functional dental implant coatings delves deep into research showing how titanium nitride (TiN) and diamond-like carbon (DLC) coatings can increase the life of dental implants. Although artificial dental implants are the most trusted solution for mature tooth loss, they can and sometimes do fail. Kamath found that TiN and DLC coatings, applied correctly, can increase dental implants’ longevity and value. These coatings protect the abutment-implant interface from higher friction sources, abrasive wear, and fatigue fractures.

This figure shows the implant-abutment and screw interface requirements for longevity. This includes smooth surfaces, wear resistance, load-bearing ability, biocorrosion resistance, biocompatibility, and antimicrobial properties:

Research & results

The article details the research and results that show that with this decade’s advances in PVD and CVD finishes, these coatings are now capable of providing excellent results in biomedical applications. The VaporTech Cadence™ System was used to conduct the research. The system is designed for a range of nanostructured coatings using the patented VaporTech Remote Anode Assisted Magnetron Sputtering (RAAMS®) technology, as seen in this figure.
