Astron’s Proprietary CLEARsplint Material

CLEARsplint has been highly regarded and trusted by dentists and labs for more than 20 years. There’s no better material for making nightguards and splints that alleviate pain and prevent destruction of healthy dentition and dental work amon​g bruxing and grinding patients. CLEARsplint nightguards are nearly invisible when worn and self-adjusting for increased patient comfort.

Both varieties are amine and methyl methacrylate-free, so they will never yellow and eliminate MMA allergies.




Self-adjusting, with superb accuracy for the closest fit, which not only makes for greater patient comfort but reduces chair time.

CLEARsplint’s dimensional stability means fewer adjustments, and the mixed formulation can be press-packed or poured. Repairs can be made using a cold cure acrylic or the original material.

Patients love the optical clarity, wearability, and comfort.

Available in flexible or regular and in 3 sizes: 

  • Lab Kit (120g liquid, 160g powder)
  • Economy Kit (240g liquid, 320g powder)
  • Super Economy Kit (720g liquid, 960g powder)
