The action of two elastic activators (Bimler and Klammt) is studied in twenty Class II/1 malocclusions, with a mean age of 10.2 years and a treatment time of 2.7 years. Intercanine and intermolar widths, and "anterior arch height" (Korkhaus) were measured on models at the beginning and at the end of treatment. On lateral X-Ray films following parameters (Ricketts) were measured: facial axis, facial depth, convexity, lower facial height, and corpus axis. Conclusions are: both appliances have a good transverse response, Bimler's Gebissformer increase vertical growth, and Klammt's elastic activator decrease convexity by a more anterior mandibular positioning.
