case_images: Examination of intraoral periapical (IOPA) radiographs in relation to maxillary and mandibular incisors revealed no periapical pathology [Figure 3a and b]. Nolla's stage 6 of teeth development. No clinical significant abnormality was observed [Figure 3c]. SNMP; 38 ), proclined and protruded upper incisors (5 mm and 31 ), and rectroclined lower incisors with normal nasolabial angle. She was in Cervical Vertebrae Maturation Indicator Stage 2 [Figure 3d].

case_images: As this patient reported at an early age with Class III skeletal pattern due to mandibular prognathism, chin cup therapy [Figure 4a] was started at this stage and advised to wear it for approximately 14-16 h/day. After chin cup therapy [Figure 4b] full-arch bonding of the upper and lower arches was done using 018" slot Standard edgewise appliance.
