The Opro Shield line of mouthguards were designed by Dr. Anthony Lovat BDS, the founder of OPRO which is the largest supplier of custom mouthguards in the world.
The Opro Shield Line introduces the patented OproFin retention system which gives the OproShield line of mouth guards the best retention (fit) performance of any self-fit mouthguard in the world. The highly technological cross-sectional profile means maximum protection against front and concussive blows while keeping the palate clear for improved breathing and speech. The OproShield is the worlds most advanced self fit mouthguard.
The OproShield Ortho Bronze is the basic model in the line, but the Ortho is designed to work with Orthodontics. There are no fins, and the channel is wider to accommodate appliances in the mouth. Unlike the silver, and gold models, the inside and the outside of the bronze are the same material. However, the Ortho is only available in the bronze line.
