OPRO is the official supplier of the world's largest combat sports organization, the UFC. 
Here the mouthguard model “Silver”:The two-layer mouthguard from Opro, with a durable outer layer for more impact protection (compared to the bronze level)
What's new in 2022: The cage for perfect adjustment, which was previously only included with the PowerFit, is now also included with the Silver level.
With this tool, which is unique on the market, you can customize your OPRO mouthguard even better!
The patented, unique lamella technology from Opro is used here.
With Opro, there is no gel inside the mouthguard shell, but upright lamellae (fins).
These fins are then distributed by the teeth during fitting in hot water and wrap around the teeth to ensure maximum protection.
This prevents excess gel, which usually escapes to the side with standard mouthguards, from interfering with the fit and comfort.
The innovative stretch zones (three small indentations distributed over the edge of the mouthguard) also ensure that the shell can expand with a wide set of teeth and contract with a narrow set of teeth. 
The result is the perfect mouthguard for everyone.
The Opro-Silver mouthguard also comes with a handle, making it very easy to remove the mouthguard from the hot water using the handle.
The prongs of the handle also ensure that you cannot bite through the mouthguard when adjusting it, so you can adjust the Opro-Silver perfectly to your teeth with maximum pressure and maximum biting.
In addition to protecting your teeth, the Opro mouthguard also offers ideal protection against jaw and facial injuries and concussions.
