Fabrication of 3D Printed Modified Activator for Correction of Skeletal Class II Malocclusion: An Innovative Modification

Activator is a commonly used appliance that Andresen and Haupl created to correct retrognathic mandible in 1908. The appliance opens the bite, and the mandible is advanced for class II correction. However, it has disadvantages like strenuous laboratory work (back office work) and any error leading to ill-fitting. Whereas the advantages of a 3D printed activator over a conventional one can be less chair-side time, high-quality finish, relatively fast, good accuracy, etc. Thus, we introduce 3D printed activator a novel modification in the present fabrication method to make it more precise and ease the back office work.
