Abstract
To evaluate the anterior-posterior (A-P)/medial-lateral (M-L) dimension, and morphology of the mandibular condyle in patients aged 18 to 65 years with Class I skeletal pattern on Cone Beam CT scans. Materials and Methods: Seventy one scans were evaluated using RealScan 2.0 software. The dimension was determined by points A (most anterior in the sagittal plane), P (most posterior in the sagittal plane), M (most interior in the coronal plane), L (most exterior in the coronal plane). The morphology of the condyle was evaluated in two coronal and sagittal planes, being classified as: round, flat, convex or mixed. The size of the condyle was analyzed by descriptive statistics and the morphology by frequency distribution. For the bivariate analysis, the Student's t-test was applied. Results: Measurements were obtained for the A-P diameter of the right condyle (RC) (8.72mm ± 1.25mm) and the left condylar (LC) (8.50mm ± 1.50mm), the M-L diameter of the RC (19.24mm ± 2.03mm) and the LC (18.97mm ± 1.87mm). There were significant differences in the male M-L dimension of the LC compared to the female (p=0.002). The most prevalent morphology of RC (35.21) and IQ (23.94) in the coronal plane was round. Conclusion: The A-P dimension of the right and left condyle is similar in both genders; however, there are differences in the M-L dimension of the left male condyle. The most prevalent morphology of the right and left condyle was round in the sagittal plane with the exception of the coronal plane.
Highlights
The occlusion skeletal pattern is the relationship between the maxilla and the mandible in an anteriort] posterior profile.[1]
In the 71 Cone Beam Computed Tomography scans (CBCTs) evaluated, it was found that the A-P diameter of the right condyle had a mean of 8.72mm ± 1.25mm and 8.50mm ± 1.50mm for the left condyle
The M-L diameter of the right condyle had a mean of 19.24mm ± 2.03mm and 18.97mm ± 1.87mm for the left condyle. (Table 1) Regarding the morphology of the mandibular condyle, it was found that in the coronal plane the most frequent morphology for the right condyle was round (35.21%), flat (30.99%), angled (22.54%) and mixed (11.27%); for the left condyle it was: round (23.94%), flat (30.99%), angled
Summary
The occlusion skeletal pattern is the relationship between the maxilla and the mandible in an anteriort] posterior profile.[1]. Dimension and morphology of the mandibular condyle in Class I patients in cone beam computed tomography. 3D images – from Cone Beam Computed Tomography (CBCT) - are an effective complementary method for the study of the mandibular condyle.
