Treatment of class II malocclusion due to maxillary protrusion can be done with bilateral maxillary first premolar extraction followed by en-masse retraction of upper anterior teeth using mini-implants placed at infrazygomatic or interradicular sites.\n\nAims and Objectives: To evaluate the treatment changes achieved in class II division 1 malocclusion during en- masse retraction of upper anterior teeth using mini-implants placed at infrazygomatic crest versus interradicular sites.\n\nTo compare patients' and orthodontist's perceptions of treatment being done in both the groups.\n\nMethod of study: Treatment will be initiated by bilateral maxillary 1st premolar extraction followed by bonding 0.022\" slot MBT preadjusted edgewise appliance. Maxillary arch will be stabilized with the help of 0.019\"×0.025\" stainless steel wire and then randomized allocation of the patients into 2 groups-G1 and G2 will be done. G1 will receive infrazygomatic crest mini-implants bilaterally and G2 will receive bilateral interradicular mini-implants. Hooks will be soldered on archwire used for stabilizing dentition. Ni-Ti closed coil spring will be used to apply force.",[82],"CLASS II DIVISION 1 MALOCCLUSION","2026-02-08",{"date":85,"type":86},"2026-02-12","ACTUAL",{"date":88,"type":86},"2025-10-01",{"date":90,"type":76},"2027-02",{"name":5,"class":6},1]
