Topographic and chemical surface modifications to metal brackets after a period in the mouth.

Introduction: In the current state of our knowledge, the effects of corrosion on the performance of orthodontic appliances and on patient health are far from clear. Awareness of these problems has led to a growing demand for nickel-free products. Titanium brackets were recently launched on the market as an alternative to stainless-steel brackets.

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 correction of a Brodie syndrome case related to oral habits].

Unilateral Brodie bite, called also Scissor bite, is a form of transversal malocclusion that often leads to minor facial asymmetry. The prevalence of this form of malocclusion is rare, especially met in mixed denture. We report a case of 11-year-old girl who presents unilateral scissor bite related to oral habits, with a skeletal class II.
