Area of Science:

  • Dentistry
  • Orthodontics
  • Radiology

Background:

  • Accurate skeletal maturation assessment is crucial for orthodontic treatment planning.
  • Current methods rely on hand-wrist radiographs or established cervical vertebrae classifications.

Purpose of the Study:

  • To validate a novel radiographic method for assessing skeletal maturation using cervical vertebrae.
  • To compare the accuracy of this new method against existing classifications.

Main Methods:

  • Lateral cephalometric radiographs of 958 Spanish children (5-18 years) were analyzed.
  • A new method evaluating cervical vertebral body morphology (concavity, height, shape) was developed.
  • Correlations were calculated between cervical vertebrae maturation and hand-wrist skeletal maturation (Grave and Brown classification).

Main Results:

  • All correlation coefficients between methods were statistically significant (P < 0.001).
  • The new cervical vertebrae maturation method demonstrated high reliability.
  • The novel method showed accuracy comparable to the Hassel and Farman classification and superior to the Lamparski classification.

Conclusions:

  • A simple, reliable method for evaluating skeletal maturation using cervical vertebrae morphology has been developed.
  • The concavity of the lower border of the vertebral body is the most effective parameter for maturation assessment.
  • This method offers a valid alternative for predicting skeletal maturation in clinical practice.
