The relationship between maxillary midpalatal area thickness with different skeletal patterns, age, and sex in cone-beam computed tomography in referal patients to Tabriz dental faculty in 2021-2022

Abstract

Background: The palatal area is the most favorable area for mini-implant placement. Sufficient amount of bone at the placement site can affect the success or failure of the anchorage device. The purpose of this study was to investigate the relationship between the thickness of the midpalatal region of the maxilla with different skeletal patterns, gender and age in cone beam computed tomography in patients referred to Tabriz Dental Faculty.

Materials and Methods: In this retrospective study, in 159 samples, 20 points in the coronal sections of the midpalatal region of the maxilla were examined in individuals with skeletal class one, class two, and class three, using CBCT software. In order to determine which group (class 1, class 2 or class 3) the patient is in terms of the horizontal skeletal pattern, two types of angular (ANB angle) and linear (wits) evaluation were used. 24SPSS software and ANOVA, Tukey's post hoc test and t-test were used to analyze the data.

Results: The average thickness of the whole bone (at 20 points) in different skeletal patterns has a P value of 0.549. In calculating the total bone thickness (at 20 points), the P value was 0.279 in women and 0.727 in men. In calculating the average thickness of soft tissue (at 20 points) in three skeletal classes, the P value was equal to 0.492. In calculating the thickness of soft tissue in all three types of skeletal classes in comparison with gender, the P value was 0.050. In calculating the thickness of the soft tissue in the comparison of the hips, the value of Pvalue was equal to 0.026 in class one, equal to 0.401 in class two, and >0.001 in class three.

Conclusion: Total bone thickness in skeletal classes 2 and 3 was higher in men than women, but there was no relationship with age. The average thickness of soft tissue had no significant difference in three skeletal classes. In all three types of skeletal classes, the thickness of soft tissue was more in men than in women and had a significant relationship with age. The thickness of the midpalatal region of the maxilla had no significant relationship
