Cone-beam computed tomography study of condyle position in high-angle adult female patients with different sagittal skeletal malocclusion

To measure and compare condyle-related indexes(volume, surface area, anterior space, upper space and posterior space) in adult female patients with different sagittal malocclusions with the aim of providing a reference for clinical treatment.

The CBCT database of Qingdao Stomatology Hospital was searched to identify patients with high-angle adult skeletal malformations with the following classifications: class Ⅰ(n＝30), class Ⅱ(n＝30), and class Ⅲ(n＝30). The CBCT images associated with the sample population were stored according to DICOM3.0 medical digital image communication standards. Mimics10.01 software was used to read and prepare three-dimensional reconstructions of the condylar, and the above-listed indicators were measured and statistically analyzed.

There were no significant differences between the right and left sides among the three groups (P > 0.05). For parameters including condylar anterior joint space and post-joint space, the differences among the three groups were significant (P < 0.05). There was no significant difference in parameters related to condylar articular space between class Ⅰ and class Ⅱ(P > 0.05). The differences between skeletal classes Ⅰ and Ⅲ and between skeletal Classes Ⅱ, and Ⅲ were statistically significant (P < 0.05).

Condylar position varies among high-angle adult woman with skeletal malocclusions with different sagittal skeletal patterns.
