Effect of Maxillary Third Molar Extraction vs. Non-extraction on Distalization of First Molars in a Group of Adolescent Patients
Class II Malocclusion
About this trial
This is an interventional treatment trial for Class II Malocclusion focused on measuring Infra-zygomatic mini-implant, Distalization, Infra-zygomatic crest, Digital models, molar tipping
Eligibility Criteria
Inclusion Criteria: Adolescent patients aged 16-19 years skeletal Class I bilateral Class II molar relationship. defined by at least an end-to-end molar relationship. normal vertical growth pattern. full permanent dentition with unerupted upper third molars. Exclusion Criteria: skeletal Class II or Class III relationship. past orthodontic treatment. poor oral hygiene. Increased vertical dimension.

Third molar extraction group
Third molar presence 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.
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.
