LM Activator


LM-Activator is an activator and aligner for orthodontic treatment. With LM-Activator, alignment, leveling and anteroposterior correction can be done at the same time without separate phases. A large assortment of models makes it possible to select the appropriate LM-Activator for the patient without need for individual modifications. Treatment complexity for both the clinician and the patient can be reduced.

LM-Activator 2 is the next generation of LM-Activator with improved features and functionality in materials and design:

  • Narrow and Wide models supporting different arch widths
  • reinforced incisal area for improved rigidity and wear resistance
  • improved manufacturing technologies and highest surface quality

LM-Activator 2 is made of clear medical grade silicone, which is biocompatible and additive free. No phthalates or other softeners, PVC, coloring agents, fragrance agents, latex or bisphenols.

LM-Activator 2 Models
LM-Activator 2 is available in the following versions (same as for LM-Activator):

  • Low Short
  • Low Long
  • High Short
  • High Long

A new version supporting a wider dental arch width is introduced and it is now possible to choose between Narrow and Wide versions of LM-Activator 2, depending on the arch widths of the patient.

In addition, all above mentioned versions are available with or without incisal reinforcement. The Reinforced alternative has a rigid reinforcement of harder material in the incisal area and is designed especially for skeletal deep bite cases. It is also suitable for other patients who benefit from a firm surface and improved durability.

LM-Activator 2 models & Usage Recommendations

  • Short: Shorter molar section, applicable when second molars have not yet erupted
  • Long: Longer molar section, applicable when second molars have erupted or will erupt soon
  • Low: Applicable for treating many different cases, except open bite
  • High: For skeletal and dentoalveolar open bite cases, thicker in the region of second premolars and molars
  • Narrow: Narrow or regular dental arch width (same as in current LM-Activator)
  • Wide: Wide dental arch width
  • Reinforced: Reinforced in incisal area for improved durability, e.g. for deep bite cases
  • Without reinforcement: For patients not requiring additional durability in incisal area
