Evaluation of cuspid cortical anchorage with different sagittal patterns using cone-beam computed tomography: a...

Area of Science:

• Orthodontics
• Dental Anatomy
• Radiology

Background:

• Limited research exists on cortical anchorage resistance in cuspids.
• Understanding cuspid anchorage is crucial for orthodontic treatment planning.

Purpose of the Study:

• To characterize cuspid cortical anchorage in relation to sagittal skeletal classes.
• To utilize cone-beam computed tomography (CBCT) for detailed analysis.

Main Methods:

• CBCT scans from 208 individuals (104 men, 104 women) were analyzed.
• Participants were categorized into skeletal class I, II, and III malocclusion groups.
• Statistical analyses included ANOVA and multiple linear regression.

Main Results:

• Cuspids were consistently close to the labial bone cortex across different skeletal patterns.
• Apical root position varied significantly, but middle and cervical root portions showed no significant difference.
• An appropriate root control angle of approximately 6° may prevent root contact with the labial bone cortex.

Conclusions:

• Dental compensation effectively manages cuspid positioning despite sagittal skeletal discrepancies.
• Tailored treatment strategies for cuspids based on skeletal patterns can optimize treatment duration and stability.
• Further research into cuspids' morphology and periodontal status is recommended.
