Introduction:
The purpose of this study was to compare the bone thickness of the palatal areas in different palatal index (PI) groups.
Materials And Methods:
Cone-beam computed tomography scans of 10 subjects were selected with ameanage group of 18 years. The measurements of palatal bone thickness were made at 36 sites using CareStream 3D Imaging software. The PIwas measured using Korkhaus ratio (palatal height/palatal width). One-way analysis of variance was used to analyze intergroup differences, as well as the PI difference.
Results:
Bone thickness was higher in the anterior region than in the middle and posterior regions P <0.001. Furthermore, significant differences were found among the midline, medial, and lateralareas of the palate.
Conclusions:
These findings might be helpful for clinicians to enhance the successful useof temporary anchorage devices in the palate.
