Abstract

Titanium dental implants are often modified for enhanced osseointegration and antibacterial activity using techniques like sandblasting, acid etching, anodization or antibacterial coatings. However, these modified surfaces are highly reactive and hence prone to contamination during storage which may decrease their bioactivity. Therefore, evaluating the long-term shelf-life stability of modified implants is a critical step before clinical translation. In the present study we report the shelf-life assessment of titanium implants modified with nano coatings of Silver (Ag) and Cobalt (Co) using DC Sputtering. The coated discs were stored in oxygen and nitrogen-purged sealed bottles for 33 days at 60℃, simulating one year of storage at 25℃ (ASTM F1980-16 method). Following storage, biocompatibility was evaluated using MG-63 osteoblast cells while antibacterial activity was assessed against Streptococcus sanguinis and Aggregatibacter actinomycetemcomitans using a modified JIS Z 2801 method. Both surfaces after accelerated aging retained 100% of their antibacterial activity along with cell viability and attachment. Among the two, Ti-Co displayed maximum cell spreading as compared to Ti-Ag surfaces. This is one of the first studies to demonstrate long-term shelf-life stability of Ag and Co modified titanium implants, addressing an often-overlooked aspect viz., performance after storage. Further studies on in vivo compatibility are warranted to further validate their long-term biocompatibility and clinical translation.
