[The craniofacial architecture of class III malocclusion using the Coben analysis].
In this study, longitudinal tracings of dental and skeletal Class III malocclusion group are compared to tracings of COBEN analysis standard values. Cephalometric measurements and surimpositions illustrate the dynamic variations of Class III cranio-facial architecture for two age ranges: 8 years +/- 1 year and 16 years +/- 1 year. The Class III pathology for children 8 years +/- 1 year aged is characterized by alterations of tracings sizes and position with excessive cranio-facial components length and rotation of cranial base into a more vertical position. A growth rate deficiency in length with a variable individual adaptation is showed for cranial structures except the mandibule after growth at the age of 16 years +/- 1 year.
