Purpose:
According to the functional matrix theory, the development of maxillomandibular complex may be affected by the surrounding tissues. The aim of this study was to evaluate the length and angulation of the styloid process in different types of malocclusions using cone-beam computed tomography (CBCT).
Methods:
Angulations and length of the styloid process were evaluated in CBCT images of 97 individuals retrospectively. The patients were classified as class I, II, and III groups according to sagittal skeletal classes. The mean length, anterior angulation, and medial angulation of the styloid process were analyzed. Statistical significance was evaluated at p < 0.05.
Results:
The mean styloid process length in group class III was found to be significantly longer than class I (p: 0.035). Anterior angle was significantly higher in class III group than in other groups (p < 0.05). No statistically significant difference was found in medial angle between the groups (p: 0.506).
Conclusion:
According to present findings, class III malocclusion is associated with the stylohyoid complex morphology due to longer styloid process lengths and higher anterior angle values.
