Differences in maxillary height in patients with maloclussion versus patients without maloclussion

Resumen

Maxillary height is an understudied etiological factor of malocclusions since most of the research on the maxilla has been carried out in the sagittal plane. The objective of this research was to assess if there are differences in maxillary height between patients without malocclusion and with malocclusion in a population from Nayarit. Material and methods: The size of the sample was 180 lateral X-rays; 45 were of patients without malocclusion so 45 X-rays of each Angle malocclusion were chosen randomly. Descriptive statistics and the ANOVA test were performed in the program SPSS version 18. Results: Patients without malocclusion had a difference of 0.5o with respect to the standard of Ricketts, class II malocclusion was the most altered value of maxillary height and Angle class III malocclusion was the one that was closest to the Ricketts standard. Conclusion: There are statistical signifi cant differences in maxillary height between malocclusions.
