title: [Cervical vertebrae: Mandibular growth dynamism indicators?].
abstract: A study of mandibular growth maturation was performed on a population of 103 patients           during orthodontic treatment (69 girls and 34 boys) from 11 to 16 years, having initially           a Class II skeletal discrepancy. The relationship between wrist maturation indices and the           cervical vertebrae maturation was studied by Lamparski classification. Significant           correlations were found between Björk stages, MP3=, MP3 cap and MP3 U and respectively           Lamparski stages as CVS 2, CVS 3-4 and CVS 5-6. This retrospective longitudinal study           identified three mandibular variables at three different maturation stages according to           Björk classification and to the six stages of Lamparski classification. The relationships           between these different maturation stages and a quantitative mandibular response permit to           estimate optimal time for our orthodontic therapy. The results indicate a significant           increase in mandibular length between CVS 4 and CVS 5, suggesting the persistence of a           condylar response to a stimulation therapy after CVS3 or CVS 4 stages (MP3 cap).           Mandibular growth seems to continue after MP3 U stage or CVS 5 stage.
