Difference in Incisal sum analysis in STL models and DICOM files of University of Cuenca students

Abstract

A cross-sectional study was carried out among the students of the 7th cycle of the State University of Cuenca where the incisal sum of each student was analyzed by using STL models with the Nemocast program and by using tomographies with the Sidexis 4 program. It was possible to use a wide universe previously obtained from a database of 40 students, provided by the University of Cuenca, of which 19 were randomly chosen to be able to analyze the data without the aim of distorting and manipulating the data released. Through a meticulous evaluation of the analyzed data of the incisal sum of the 19 people, we proceeded to order the values ​​and standardize them, however, for a greater impact and veracity in the study, we proceeded to analyze the data and propose an alternative hypothesis: which would be corroborated through the "T Student" method. Finally, it was possible to find the values ​​of the mean and variance of each data grouping (format and incisal sum). Theoretical framework: To carry out this study, it is important to know that different orthodontic measurement parameters and different software used were used. These elements will be disclosed below. Mayoral analysis: This method can be used in permanent occlusion and allows estimation of the relative distances between the grooves that separate the buccal cusps from the lingual cusps of maxillary first and second premolars, and between the midline grooves where the mandibular cusps meet, the first molars of the maxilla. converge and normal patients should have dimensions of 35, 41, and 47 mm, respectively. When the value obtained is lower than the norm, a diagnosis of transverse micrognathism is obtained, and when a higher value is obtained, a diagnosis of transverse micrognathism is. [1] The disadvantage of this method is that the cross-sectional assessment is only performed in the maxilla and not in the mandible. [1] Nemoceph: NemoCast is an orthodontic software that allows you to perform digital cast analysis, digital diagnosis and planning, and export and print products.
