SDI Limited announced regulatory approval has been received from US Food and Drug Administration (FDA) for SDI's amalgam replacement product `Stela'. Stela is a newly developed and innovative product that meets market demand for a highly durable tooth coloured amalgam alternative. For decades, dentists have used amalgam, silver in colour, for fillings due to its unmatched durability, low cost, and ease to place.

Changing consumer preference for tooth-coloured fillings presented the industry with the challenge and opportunity to develop a product that has the matched durability of amalgam, but tooth coloured. Stela meets this demand. Stela technology is the result of a strong partnership between SDI's scientists, with 50 years of experience developing dental materials, and aeronautical engineers from the University of New South Wales (UNSW), University of Wollongong and University of Sydney, world leading Australian universities.

Stela was developed over a 5-year time frame via a rigorous and scientifically proven process and supported by government via grants.
