Treatment of adult Class II division 2 patient with metal hypersensitivity

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 completion of the active treatment.
