Study Groups
Review each arm or cohort in the study, along with the interventions and objectives associated with them.
Third molar extraction group
After surgical extraction of unerupted upper third molars, the maxillary first molars were distalized using the infra-zygomatic gear distalizer, which is anchored to infra-zygomatic mini-implants inserted in the infra-zygomatic crest.
Distalization combined with upper third molars extraction
After surgical extraction of unerupted upper third molars, the maxillary first molars were distalized using a labial bow with two soldered crimpable hooks distal to the upper lateral incisors. The labial bow fitted in the flying tube of the upper first molar bands. It was anchored bilaterally to the infra-zygomatic mini-implant by closed coil spring that applied a force of 300gm on each side
Third molar presence group
Without extraction of unerupted upper third molars, the maxillary first molars were distalized using the infra-zygomatic gear distalizer, which is anchored to infra-zygomatic mini-implants inserted in the infra-zygomatic crest.
Distalization without upper third molars extraction
The maxillary first molars were distalized , without extracting upper third molars, using a labial bow with two soldered crimpable hooks distal to the upper lateral incisors. The labial bow fitted in the flying tube of the upper first molar bands. It was anchored bilaterally to the infra-zygomatic mini-implant by closed coil spring that applied a force of 300gm on each side
