Brief Summary

Review the sponsor-provided synopsis that highlights what the study is about and why it is being conducted.

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.

Detailed Description

Dive into the extended narrative that explains the scientific background, objectives, and procedures in greater depth.

This study aims to assess the stability of tooth position and occlusal retention during treatment with two types of retainers, Essix type retainer and the retainer plate type Hawley in individuals who have completed their growth ending orthodontic treatment at the Faculty of Dentistry University of Antioquia and CES University Medellín

Study Groups

Review each arm or cohort in the study, along with the interventions and objectives associated with them.

Essix retainer

Group Type EXPERIMENTAL

Essix retainer

Intervention Type DEVICE

The essix retainer is made in a thermoforming copolyester 0.75mm (0.30 ", it processed gives a thickness of 0.015" approximately. Retainer will be used molar to molar. subjects in this arm will have this retainer for 24 hours a day for 6 months, they won´t have this device for food intake.

Hawley retainer

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.

Group Type ACTIVE_COMPARATOR

Hawley retainer

Intervention Type DEVICE

subjects in this arm will have the retainer for 24 hours a day for 6 months. During food intake they won´t have this device.
