Adams clasp 0.7 mm hard, labial arch 0.7 mm spring hard
Function:
Alignment of the incisors
Description:
The incisors are aligned with a set-up which is transferred with an acrylic covered labial arch
A slight anterior crowding or wrong position of the incisors can be compensated with a set-up from canine to canine. The plaster model has to be duplicated for the making of the appliance.
Adams clasps with soldered tubes are used as retention elements. The distal part of the labial arch, which is covered with acrylic in the anterior region, is inserted into the molar tubes which serve as guide rails.
Both sides of the labial bow have small loops distal of the incisor coverage. From these loops, elastic springs are attached to the distal endings of the labial bow that slide out of the molar tube. This way, a continuous pressure is applied on the incisors which results in their alignment according to the set-up.
