Class III malocclusion is highly prevalent among Asian population, especially in the form of a midface deficiency. This case report describes three such cases that have been treated using growth modification and orthodontic decompensation with orthognathic surgery. Case report 1 is of a 12 years old female patient having Angle’s class III malocclusion based on skeletal class III jaw bases with 12 mm of reverse overjet, 0 mm of overbite, proclined maxillary anteriors, retroclined and crowded mandibular anteriors and rotated 13 and 23. Case report 2 describes a 12 years old male patient diagnosed with Angle’s class III malocclusion based on skeletal class III jaw bases with 2 mm of reverse overjet and 5mm of overbite and anterior crossbite i.r.t. 11,12-31, 41. Case report 3 demonstrates a 22 years old male patient with Angle’s class III malocclusion based on skeletal class III jaw bases with 3 mm of reverse overjet and -2
mm of overbite with proclined maxillary anteriors and retroclined mandibular anteriors; spacing in the upper anteriors and crowding in lower anteriors, with anterior crossbite.Treatment in all the cases achieved good functional stability.
