optimill crystalign is intended to be used in the patient's mouth for orthodontic splints. The milling blanks have a very high material homogeneity due to the industrial polymerisation process. The balanced combination of breaking strength and elasticity for clinical use guarantees excellent long-term stability. optimill crystalign has excellent abrasion resistance. The material ensures high process reliability, no mixing errors, no polymerization shrinkage and no unpleasant odor.
