Sumario:The objective of this study was to determine the relationship between the presence of bone defects (fenestrations and dehiscence) observed from lateral slices taken from a computerized axial tomography (CAT) seen from the ImplantViewer software and the presence of maxillo-mandibular transverse discrepancies present in these CT scans analyzed from a posteroanterior view (PA) of the skull studied in the Dolphin Imaging software. The sample consisted of 160 computerized axial tomographies (TAG) of orthodontic pretreatment patient files between 9 and 25 years of age that attended a Radiological Center in Guadalajara Jalisco from 2009 to 2012. The sample was divided into 8 age groups (Group 1 - 9 years, Group 2 - 10 years, Group 3 - 11 years, Group 4 - 12 years, Group 5 - 13 years, Group 6 - 14 years, Group 7- 15 years and Group 8 - 16 years and up). The presence of bone defects (fenestrations and dehiscence) was observed in maxillary parts (first premolars, second premolars and maxillary first molars). We proceeded to measure the maxillary width (Mx-Mx) and mandibular width (Ag-Ag) to later calculate the maxillo-mandibular discrepancy ([Ag-Ag) - [Mx- Mx)). Once the data were obtained, t and Chi square tests were carried out to correlate the variables. The first correlation analysis was determined between the age of the group and the average maxillo-mandibular discrepancy of the same, finding statistically significant differences between each of them. On the other hand, once the association between maxillo-mandibular discrepancy and bone defects was analyzed, no statistically significant differences were found.
