Summary
Midpalatal bone density (BD) is higher in females and increases with age. Class II skeletal patterns show lower BD than Class III, impacting treatment planning.
Area of Science:
- Orthodontics
- Dental Imaging
- Anthropology
Background:
- Midpalatal suture bone density (BD) is crucial for orthodontic treatment success, particularly for procedures like rapid maxillary expansion.
- Understanding factors influencing midpalatal BD can optimize treatment outcomes and predictability.
Purpose of the Study:
- To evaluate midpalatal bone density (BD) using cone-beam computed tomography (CBCT).
- To analyze BD variations based on gender, age, and skeletal patterns (vertical and horizontal).
Main Methods:
- CBCT images of 126 subjects (64 females, 62 males) were analyzed for midpalatal suture BD.
- Subjects were classified into four age groups and three vertical and horizontal skeletal pattern categories.
Main Results:
- Females exhibited significantly higher midpalatal BD than males (p < 0.001).
- Midpalatal BD significantly increased with age (p < 0.001).
- Class II subjects had significantly lower BD than Class III subjects (p < 0.05), with no significant differences across vertical skeletal patterns.
Conclusions:
- Gender and age are significant factors influencing midpalatal bone density.
- Skeletal Class II may present unique challenges for midpalatal expansion due to lower bone density.
- These findings aid clinicians in anticipating patient anatomy and potential treatment complexities.
