Essix Retainer vs Hawley Retainer

PHASE 3 STUDY OF THE EFFECTIVITY OF TWO RETAINERS IN THE DENTAL AND OCCLUSAL STABILITY

• Status: Unknown
• Phase: Phase 3
• Study type: Interventional
• Enrollment: 46 (estimated)
• Sponsor: CES University · Academic / Other
• Sex: All
• Age: 16 Years – 40 Years
• Healthy volunteers: Not accepted

Summary

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

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

Conditions

• Dental and Occlusal Stability

Interventions

Type	Name	Description
DEVICE	Essix retainer	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.
DEVICE	Hawley retainer	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.
