Objective. To determine if there is a difference between the transverse sizes of the maxillary lateral incisors in the different Angle malocclusions and to determine the prevalence of maxillary lateral incisors with microdontia in the different Angle classes. Methods. The research is descriptive, transversal and observational. The study universe was 780 orthodontic pre-treatment study models. The sample was 190 study models. Binder and Cohen's method was used to determine the presence of microdontia. Results. In Class I malocclusion a frequency of microdontia of 32% was found, in Class II malocclusion it was 35% and in Class III malocclusion it was 26%. The upper lateral incisors with microdontia and without microdontia have a statistically different mean between them at a confidence level greater than 95%, this difference is observed homogeneously in each of the malocclusions. Conclusio...

Objectives: To assess the cortical bone thickness of incisors when proclined and normo-positioned according to skeletal Class I and Class II malocclusions. Material and Methods: This study was descriptive, cross-sectional and observational. The study population consisted of 1220 pre-orthodontic treatment CBCT (Cone Beam Computed Tomography) scans from the archive of the Autonomous University of Nayarit between 2015–2023. The final sample included 76 scans. Inclusion criteria were as follows: diagnostic records containing CBCT scans of patients aged 12–40 years with no prior orthodontic treatment or anterior dental crowding. Incisor positioning was standardized for CBCT measurements. Data recording and descriptive statistics were performed using Microsoft Excel. Student’s t-tests were conducted using StatCalc software. Results: In the maxilla, both in Class I and II, when the inciso...

Objective: To determine if the fa cial biotype and the pattern of facial growth agree in women and men. The study universe was 673 lateral radiographs of skull pretreatment of orthodontics. The sample was 100 radiographs of which 50 were of each sex. The average age in women was 13.7 years and in men 17.08 years. Ricketts VERT and Jarabak's facial height ratio were performed. The data was captured on the electronic record sheet and descriptive statistics were performed in the Microsoft Excel program. The Kappa test was performed in the calculator in Excel for the Kappa-Fisterra Index and the Student t tests were performed in the SPSS 19 program. Results: the mesofacial facial biotype was found in women 48% and in men with 44% the dolichofacial biotype. The average of VERT was -0.356 in women and in men of -0.31. The growth pattern 65.28% in men and women of 62.25%. The result of the Kapp...

Objetivo: determinar si existe diferencia entre el cálculo de la discrepancia oseodentaria de forma ma-nual y utilizando la aplicación iModelanalisys2. Materiales y método: Se conformó una muestra por conveniencia de 120 modelos de estudio pretratamiento de ortodoncia. Se procedió a realizar la me-dición de todos los órganos dentarios tanto de la arcada superior como inferior, así como la longitud total de ambos arcos con un calibrador digital y calculadora. Posteriormente se realizó el calculo de la discrepancia oseodental introduciendo los datos obtenidos en la aplicación iModelAnalysis2, en un Smartphone. Resultados: El promedio de edad de la muestra fue de 17 años. En el maxilar la media de la discrepancia ósea dentaria al calcularlo de forma manual fue de -3.7mm y al calcularla con el progra-ma iModelAnalysis2 el promedio de la discrepancia óseo dentaria fue de -3.22mm....

Objective: Determine whether there is a difference between the calculation of the discrepancy osseoden-tal manually and using the iModelanalisys2 application. Materials and method: A convenience sample of 120 models pretreatment orthodontic study was formed. We proceeded to perform the measurement of all dental organs of the upper and lower arch, and the total length of both arches with a digital caliper and calculator. Subsequently, the calculation discrepancy oseodental entering the data obtained in the iModelAnalysis2 application in a smartphone. Results: The average age of the sample was 17 years. In the maxillary average dental bone discrepancy to manually calculate it was -3.7mm and calculate the average program iModelAnalysis2 dental bone discrepancy was -3.22mm. In the mandible, the diffe-rence between using the application and do it manually discrepancy of 0.5mm. When comparing ...
