Summary

: the purpose of this study was to evaluate the dento-skeletal effects of the mini-implant supported Twin Block versus the incisal capped appliance in the treatment of skeletal class II patients with mandibular retrognathism.

Methods: Twenty patients with skeletal class II mandibular retrusion were included in the study. They were recruited with a random and equal allocation into 2 groups. The first group was treated with incisal capped TB without skeletal anchorage. The second group were treated with mini-implant supported TB. The mini-implants were inserted in the inter-radicular region between the mandibular second premolar and first molar. Intra-oral elastics were attached from the mini-implant to the wire hook in the canine region of the lower part of the TB and they were changed every 24 hrs. 100 to 150 gm of force was applied. Cephalometric radiographs were acquired at the beginning (T1) and end of treatment (T2). The paired-samples and independent-samples t-tests were used to evaluate and compare the changes within groups and between groups, respectively.

Conditions

  • Class II Malocclusion

Interventions

DEVICE

skeletal anchored twin block

This appliance was constructed as the modified Twin Block used for the first group in addition to the following modifications: * Addition of mini-implants interdentally between the mandibular second premolar and mandibular first molar. * Wire hooks: wire hook element in the lower part of the appliance was incorporated in the region of incisal capping with free end projecting at the canine region on both sides. * Intra-oral elastics were attached from the mini-implant to the wire hook bilaterally.
