About

There are several factors involved in the decision and the retention plan, such as occlusion, patient age, etiology of malocclusion, the speed of the correction, the length of the cusps and health of the tissues involved, relationships inclined planes, size of the arches, harmony of the arches, muscle pressure, interdental proximal contact, cell metabolism and atmospheric pressure. Given these concepts, we need to find grounds to enable decision making with respect to the retainer that offers the best features of containment and stability.

Device: Essix retainer

Hawley retainer

Active Comparator group

Description:

Hawley retainer is a device composed of an acrylic base with built-in hooks and a labial arch wire 0.022 "x0.036" and attached to the teeth. Its metal component consists of two adams hooks positioned from the first permanent molar right to left, a labial bow that progresses from lingual superface to distal of canine to integrate with the acrylic base.
