Material Properties

KeyGuard. The better choice than traditional mouthguards

  • Protection: The effectiveness of protecting against dental injuries during sports activities is enhanced by the impact strength and resistance properties of KeyGuard, thus reducing the likelihood of tooth fractures and oral trauma.
  • Comfort: The combination of KeyPrint 3D printing technology, which allows for precise customization, along with the ideal balance of hardness and flexibility in KeyGuard, ensures a comfortable fit that athletes can wear comfortably for extended durations without hindering breathing or speech.
  • Durability: KeyGuard’s superior tear strength and water absorption capabilities enable it to endure the demands of athletic activities, minimizing the necessity for frequent replacements.
  • Performance: KeyGuard utilizes material characteristics such as tensile cyclic hysteresis and tensile elongation at break to absorb and disperse energy during repetitive stresses.
