Table 1: The CVMS method for the assessment of skeletal maturity (Baccetti et al., 2002).

CVMS I	The lower borders of the vertebrae are flat, with the possible exception of a concavity at the lower border of C2. Occurs at least 1 year before the pubertal growth spurt.
CVMS II	Concavities of both C2 and C3 are present. The peak in mandibular growth will occur during the year after this stage. Marks the ascending portion of the pubertal growth spurt.
CVMS III	The bodies of both C3 and C4 are rectangular horizontal. The peak in mandibular growth has occurred within 1 or 2 years before this stage. Marks the descending portion of the pubertal growth spurt.
CVMS IV	At least one of the bodies of C3 or C4 is square. The peak in mandibular growth has ended at least 1 year before this stage. Marks the end of the pubertal growth spurt period.
CVMS V	At least one of the bodies of C3 or C4 is rectangular vertical. If not rectangular vertical, the body of the other cervical vertebra is squared. The peak in mandibular growth has ended at least 2 year before this stage.
