Se describe la aparatología usada, el protocolo de tratamiento y los resultados obtenidos al final de tratamiento; como parte de los requisitos para optar el título profesional de Especialista en Ortodoncia y Ortopedia Maxilar.

This case report presents a 13 year old patient who underwent a class II division 2 type C malocclusion treatment with an extraoral headgear, regarding patient’s age and skeletal maduration stage at that moment. Th is article presents the use of extraoral forces and the skeletal, facial and dental changes that were finally achieved.

Objective: There are risks associated to the eruption of canines, by what is makes necessary a monitoring clinical early and a correct diagnosis. Cone-Beam computed tomography, in recent years has proven to be a reliable and accurate method to assess this type of complications. He objective of this study was determine the location and position of the canine impacted and its proximity to teeth adjacent through the use of the tomography CT cone-beam. Materials and methods: We evaluated72 CT scans Cone Beam patients with clinical diagnosis: maxillary canine impaction. The evaluation is carried out through the use of the system point 3D combi 500 S with the software Real Scan. Is made cuts sagittal, frontal and axial for the evaluation of it location (vestibular, Center alveolar or Palatine), position (third apical, half or cervical) and its proximity with the incisive side (≤ 1,5 mm = nex...

Objective: the proposal of this study was to examine the degree of root resorption in parts adjacent to impacted maxillary canines, bymeans of a cone-beam computerized tomographic evaluation, which has proven to be a reliable and accurate method to assess thistype of complications. Materials and methods: this study was an evaluation of 1265 ct, which obtained a sample of 72 ct with caninesimpacted maxillary, 36 men and 36 women, ranging from 13 to 43 years old. The variable studied was reabsorption of the adjacent part:the classification of levander and malmgren was used to assess the degree of root resorption. Results: it was observed that 49% hadgrade 0 reabsorption, followed by 19% grade 3 reabsorption. No statistically significant difference was found according to sex p = 0.47.This study found a greater number of patients younger than 18 years presenting root resorption of incisor si...
