Patented Dual Compression Cage Using hyperflex technology, our patented dual compression cage harnesses the power of the jaw to produce a perfect model of the mouth. This easy, quick to fit process creates a custom dentist level gum shield with unrivalled retention that rests comfortably over teeth delivering the same accuracy as a dental thermoforming machine. Patented Fin Technology Our patented self-impression fin technology is unique to the Instant Custom-Fit mouthguard. Working with the compression cage, the unique design of the hi-flow gel fins securely mould around teeth for a dentist level fit. Dental Grade Protective Shell Our Instant Custom-Fit mouthguard has a dentist level protective shell that offers the highest level of damage defence as worn by professional athletes. The cutting-edge triple layer construction dissipates shock waves from a blow cushioning impact and reducing the chances of a sports-related tooth injury. So, you can feel safer, and play better.
