Impact of the first eight months of orthodontic treatment with a fixed appliance on the families of adolescent patients.
va SM Abstract Objective: To evaluate the impact of the first 8 months of orthodontic treatment with a fixed appliance on the families of adolescent patients and to examine the evaluative properties of the Family Impact Scale (FIS). Materials and Methods: The study involved a sample of 94 parents/caregivers of adolescents undergoing orthodontic treatment with a fixed appliance. The participants were asked to answer the Brazilian version of the FIS before treatment (T1) and 8 months after the bonding of the fixed appliance (T2). Statistical analysis was carried out using the Wilcoxon signed rank test and ...

Effects of different types of tooth movement and force magnitudes on the amount of tooth movement and root resorption in rats.
Conclusions: Root resorption in the tipping tooth movement group was more pronounced than that in the bodily tooth movement group. Although the amount of tooth movement decreased when extremely heavy forces were applied, root resorption increased in both the tipping and bodily tooth movement groups in rats.

Treatment of adult Class II division 2 patient with metal hypersensitivity.
Abstract This case report describes the orthodontic treatment of an adult female with an Angle Class II division 2 malocclusion with a severe deep bite and a congenitally missing lower incisor. The use of available orthodontic devices and materials was limited because the patient had metal allergies. Following a careful examination and case analysis, the preadjusted edgewise appliances and the microscrew implants were placed after the upper first premolars were extracted. After active treatment, a good facial profile and occlusion were achieved. These results have been maintained for 2 years following complet...
