KeyGuide

KeyGuide

KeyGuide is ideal for fabricating transparent and stable surgical guides, which enable the placement of implants at a precise angle and depth.

Features

  • Strong
  • Biocompatible
  • Easy to polish
  • Autoclavable and colour stable

Flexural Modulus


Higher flexural modulus prevents the model from distorting, which can impact accuracy.

Flexural Strength


Higher flexural strength ensures that the model doesn’t break during normal use.
