    Evaluación de los cambios dentarios y su influencia en los tejidos blandos de pacientes tratados con sistema Damon Q y MBT
    (2016) Arévalo Remache, Jessica Patricia; Bravo Calderón, Manuel Estuardo
    This research was mainly aimed at establishing the dental changes and evaluate the influence thereof in the soft tissues of the lower third of the face by comparing patients treated with Damon Q (N = 23) and MBT (N = 16) system. The study sample consisted of 39 individuals, being 28 women and 11 men aged between 11 y and 26 years old. Digital cephalometric radiographs were recorded, those were taken before and after completing the treatment. The inclination of the upper and lower incisors and facial profile changes were measured by cephalometric analysis software named Nemotec Dental Studio. To determine changes in hard and soft tissues the T-Student test was applied verifying statistically significant differences (p <0.05) for the two systems in the variables maxillary and mandibular incisor angle, lower lip position as the Ricketts aesthetic plane and the plane of Burstone. The relationship between changes in the inclination of the incisors and lip position was assessed by correlation coefficient of Pearson finding for the Damon System a statistically significant correlation between the position of the upper incisor and the upper and lower lip, lower incisor position has a moderate correlation with the lower lip. Using the technical MBT a moderate relationship between the position of the upper incisor and lower lip was found. Concluding that there posttreatment changes in the position of the upper and lower incisors and lower lip protrusion finding relationship between vestibular inclination of the incisors and lip movements in both techniques
