Residual craniofacial growth: A cephalometric study of 50 cases.

Although orthodontists focus intensively on the diagnosis and treatment of their patients, they pay less attention to post-treatment development and the risk of relapse often caused by the late growth of the arches and bony base. The aim of this study, therefore, was to determine the growth changes, which can affect craniofacial dimensions in subjects aged between 13 and 17 years. A retrospective longitudinal study including 50 patients (31 girls and 19 boys) whose end of orthodontic treatment coincided with the end of the post-pubertal period (13-14 years) involved a comparison of the cephalometric analyses for each patient between T1 (end of orthodontic treatment) and T2 (end of retention).

[Orthodontic approach to asymmetry].

From an orthodontic point of view, asymmetries can be gathered in three great clinical entities: mandibular lateral deviations, dental asymmetries without skeletal involvement, skeletal asymmetries. Once the therapeutic aims and the principles of the orthodontic approach of these dysmorphoses have been recalled, the authors present the various orthodontic means implemented in this type of treatment. Four cases treated illustrate those types of treatment.

[Etiopathogenic and clinical aspects of asymmetry].

Complex dysmorphies, asymmetries can affect the various elements of the stomatognathic system: cranial base, maxilla, mandible, musculature and dental arches, in the three dimensions of space. Their etiopathogenesis, as well as their clinical forms, vary considerably. Dysembryopathies, growth disorders, TMJ damages, postural or functional disorders and dental anomalies can create, according to their severity and their moment of appearance, severe or minor facial asymmetries, or asymmetries of the arches.
