Introduction: Dental malocclusion is positioned in the 3rd place of pathology, the severity in the degree of malocclusion determines the need for treatment from convenient to priority. Orthodontic therapy is not subject to age since the treatment of malocclusion is an important factor in the quality of life of the patient. Objective: To define the degree of malocclusion present in a sample of subjects and to determine the prevalence of the need for treatment. Methods: Forty patients aged 18 to 65 years were evaluated based on the dental esthetic index. Results: The analysis of the database shows that the prevalence of the need for orthodontic treatment in some degree of urgency is 67.5%. Of the 100% of the subjects studied, 45% maintained normal occlusion, 32.5% showed a defined malocclusion. Conclusions: More than half of the general population suffers from dental malocclusion in some degree of severity with the invariable need for orthodontic treatment. Dental malocclusions continue to be a public health problem that affects not only dental esthetics with strong psychological repercussions but also the function of the stomatognathic system with depreciation in the quality of life of the patient who suffers from it., Introducción: La maloclusión dental se posiciona en el 3er lugar de la patología, la gravedad en el grado de maloclusión determina la necesidad de tratamiento desde conveniente hasta prioritario.

Objetivo: Definir el grado de maloclusión presente en una muestra de sujetos y determinar la prevalencia en la necesidad de tratamiento. Método: Se evaluaron 40 pacientes de 18 a 65 años, basado en el índice de estética dental. Resultados: Los análisis de la base de datos sustentan que la prevalencia en la necesidad de tratamiento de ortodoncia en algún grado de urgencia es del 67.5%. Del 100% de los sujetos estudiados 45% mantenía una oclusión normal, 32.5% mostraba una maloclusión definida. Conclusiones: Mas de la mitad de la población general padece maloclusión dental en algún grado de severidad con la invariable necesidad de tratamiento de ortodoncia. La maloclusiones dentales siguen siendo un problema de salud pública que afecta no solo la estética dental con firmes repercusiones psicológicas sino también la función del sistema estomatognático con la depreciación en la calidad de vida del paciente que lo padece.

Background: The aim of this study was to establish the condylar position in a group of patients with normal occlusion, compared to Class II Div 1, Class II Div 2 and Class III malocclusions using CBCT imaging. Material and methods: Retrospective case-control study carried out by analyzing CBCT images of 80 patients. The sample was divided into 4 different groups with 20 patients each (40 TMJ). All patients were positioned using the Frankfurt plane, parallel to the floor and in maximum intercuspation. The control group included asymptomatic patients with normal occlusion (Less than 2mm of tooth size-arch length discrepancy, positive or negative, 0-2mm overjet, 2-4mm overbite, less than 15o rotations, without facial asymmetries, no previous orthodontic or occlusal treatment, without muscular or articular signs or symptoms in both TMJs) and the experimental group with (class II/1, II/2 and III) malocclusions. Results: The group with normal occlusion had the condyles centrally positioned within the glenoid fossa. The values obtained in this group were considered as optimal and when compared with the other groups with malocclusions. The results established that the position of the condyle was more posterior in class II/2 and more superior in class III patients than the asymptomatic normal occlusion group. Conclusions: The data obtained in the asymptomatic group with normal occlusion could be used as a reference for future studies. The comparison of these values with those obtained from analyzing the different sagittal malocclusions show significant differences that could be valuable when establishing the diagnosis and the objectives of the treatment plan in orthodontics.

Introduction: Supernumerary teeth are considered a numerical disorder or anomaly. This anomaly can cause impacts, diastema, ectopic rash, cysts, among others.Clinical Case: Female adolescent of 13 years, went to the dental office for lack of the front tooth, examinations were made to verify the agenesis of tooth 21 and a supernumerary element even in the jaw region. The treatment plan that consisted of a surgical approach was indicated.Discussion: Supernumerary teeth occur most frequently in the maxilla. It can prevent the eruption of adjacent permanent or cause ectopic eruption, leading to crossbite in the region and diastema. Although the initial plan was to extract the supernumerary and evaluate its subsequent implantation in the agendasic site, it could not be achieved due to the angulation and presence of incomplete roots. We opted for the complete removal of the supernumerary with indication of orthodontics and prosthetics., Introducción: Los dientes supernumerarios se consideran un trastorno o anomalía numérica. Esta anomalía puede causar impactaciones, diastema, erupción ectópica, quistes, entre otros.Caso Clínico: Adolescente femenina de 13 años, acudió a la consulta odontológica por falta del diente frontal, se hicieron exámenes que constataran la agenesia del diente 21 y un elemento supernumerario incluso en región del maxilar. Se indicó el plan de tratamiento que consistió en un abordaje quirúrgico.Discusión: Los dientes supernumerarios se producen con mayor frecuencia en el maxilar. Puede impedir la erupción de permanentes adyacentes o causar erupción ectópica, conllevando a la mordida cruzada en la región y diastemas. Pese a que el plan inicial fue extraer el supernumerario y evaluar su posterior implantación en el sitio agenésico, no pudo concretarse ello debido a la angulación y presencia de raíces incompletas. Se optó por la remoción completa del supernumerario con indicación de ortodoncia y protésica.
