Introduction. Orthodontic treatment of Class II Division 1 (II/1)
malocclusions in adults can be challenging since skeletal effects are
limited. Possible treatment options are orthodontic camouflage or
orthognatic surgery, in severe cases. The aim of this paper was to present a
successful management of Class II malocclusion in an adult patient using
temporary anchorage devices (TADs). Case report. After detailed clinical
examination, study models and cephalometric analysis, a 26 years old patient
was diagnosed with Class II malocclusion, an overjet of 12 mm, congenitally
missing tooth 41 and midline shifted to the right in upper dental arch. In
prior orthodontic treatment, patient had upper premolars extracted.
Posterior teeth in upper left quadrant were shifted mesially. The camouflage
treatment was considered, using temporary anchorage devices (TADs) to
distalize posterior teeth on the left side, and gain space for incisor
retraction and midline correction in upper dental arch. Results. Using TADs
as additional anchorage in anterior region and coil spring for molar
distalization, the space was made for tooth 23, midline correction and
incisor retraction. After 40 months, a satisfactory result was achieved,
overjet and midline correction, class I canines occlusion and class II molar
occlusion. Conclusion. Class II/1 malocclusion in adults can be successfully
treated using TADs. The success depends on the severity of malocclusion and
patient cooperation.
