简要总结

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.

详细描述

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

结局指标

主要结局

Dental stability

时间窗: Up to 6 months

Dental stability will be assessed like this, models: rotation of central and lateral incisor, canine, first and second premolar, first molar on each side and each arch; and cephalometric analysis: SN-upper central incisive, FK-upper central incisive, palate plane-upper central incisive, interincisal angle, mandibular plane-lower central incisive; vertical distances: palate plane-upper central incisive, palate plane-first upper molar, mandibular plane-lower central incisive, mandibular plane-first lower molar; horizontal distances: A-Pogonion upper and lower central incisive.

次要结局

  • Occlusal stability(Up to 6 months)
