This study provides crucial age- and gender-specific maxillary skeletal dimensions for Caucasian individuals aged 8-20. These normative data, derived from cone-beam computed tomography (CBCT), aid in personalized treatment planning.
Area of Science:
- Orthodontics
- Craniofacial anatomy
- Radiology
Background:
- Limited data exists on Caucasian skeletal dimensions across various age groups.
- Normative data is essential for accurate diagnosis and treatment planning.
Purpose of the Study:
- To establish age- and gender-specific normative skeletal measurements of the maxillary region.
- Utilize cone-beam computed tomography (CBCT) for precise dimensional analysis.
Main Methods:
- Acquired CBCT images from 529 Caucasian patients (8-20 years).
- Measured seven linear variables: ANS-PNS, CF, PVD, PCEJ, VCEJ, Jug, and AL.
- Analyzed data for age- and gender-related variations.
Main Results:
- Significant dimensional changes observed in ANS-PNS and PVD from 8 to 20 years.
- Arch length (AL) exhibited minimal variability across age groups.
- Males demonstrated larger dimensions and statistically significant changes (p < .001) compared to females.
Conclusions:
- Maxillary linear dimensions show distinct variations with age and gender.
- Normative data provides a valuable reference for tailoring CBCT imaging protocols to individual patients.
