Opro, the British brand of mouthguards, has won a second Queen's Award for Enterprise in the category of innovation, this time for its patented Snap-Fit model. The previous award was conferred in 2007. According to Opro, Snap-Fit is the only mouthguard on the market that requires no boiling or molding to achieve a proper fit to the user's mouth. Sales of the product, it says, have doubled over the past two years and now account for a significant share of the company's total revenues. Opro was founded about 20 years ago by a former dentist, Antony Lovat, and is still owned by him. Its laboratory/factory is located in Hemel Hempstead, in the county of Hertfordshire, and can produce up to 3,000 mouthguards per day. The company has partnerships with a number of sports teams, such as England Rugby, New Zealand Rugby, Australia Rugby, Ultimate Fighting Championship (UFC), USA Taekwondo, Great Britain Taekwondo, Wrestling Canada Lutte, Irish Hockey and Great Britain Hockey.
