Background:

For mandibular advancement containment, it is necessary to use an appliance that holds the jaw in the achieved position by active appliances and that its design does not provoke undesired dental movements.

Objective:

To describe the clinical and cephalometric changes of the Orthodontic Appliances after the Waveney treatment as an alternative in the mandibular advancement containment.

Methodology:

A descriptive observational cross-sectional research was conducted at the Dr. Justo Ortelio Pestana Lorenzo Provincial Teaching Stomatology Clinic orthodontic service in Sancti Spíritus province, from September 2019 to February 2022. 20 patients who started their containment stage in this period and fulfilled the inclusion criteria were selected. Empirical and statistical methods were used. The following variables were analyzed: age, sex, clinical morphological and cephalometric variables, as well as the containment result.

Results:

An average age of 15.6 was found; 65% of the schoolchildren were female. One year after the containment was started, the incisive overpass was maintained at 2.95 mm, the neutroclusion molar rate at 65%, SNB angle at 79°, the ANB angle at 2.80°, the upper incisor position 2.45 mm, the lower incisor position by 1.90 mm and the esthetic profile by 0.55 mm. There was only an average increase in the incisor protrusion value from 2.70 mm to 2.75 mm.

Conclusions:

One year after containment with the Waveney post-treatment Orthodontic Appliances was initiated no changes were observed in the studied variables, except for incisor protrusion with an increase in its average value.
