Case Type:
Class II Div I - Extraction of upper 1st and lower 2nd premolars

Problem List:
Skeletal hyperdivergency
Upper incisor proclination
Extrusion of upper/lower incisors
End-on Class II buccal occlusion
Severe upper and lower arch length deficiency
Pre-pubescent, with growth remaining

Treatment Plan:
Extraction of upper 1st and lower 2nd premolars
Correction of upper and lower crowding
Reciprocal closure of extraction spaces
Avoid Cl. II elastics due to excessive incisor/gingival display
Forsus Springs™ as needed to augment anchorage
-6˚ torque bracket on 32 for additional labial root torque
CSF on the severely rotated upper incisors (UL2-UR2)
Removable upper and fixed lower retention

Maxillary arch
Extract 14, 24
Alignment with 0.016 Supercable followed by 0.014 Nickel Titanium and then 0.016 Nickel Titanium. Leveling and initiation of torque via 0.018 D Wire, followed by 0.017 x 0.022 SPEED Wire in Nickel Titanium to finalize torque correction and idealize archform. Upper arch space consolidation was accomplished using 0.018 x 0.018 x 0.018 Hills Dual Geometry Wire. The upper arch was finished using 0.017 x 0.022 SPEED Wire in Stainless Steel.

Mandibular arch
Extract 35, 45
Alignment with 0.016 Supercable followed by 0.014 Nickel Titanium and then 0.016 Nickel Titanium. Leveling and initiation of torque via 0.018 x 0.018 Nickel Titanium D Wire, followed by 0.017 x 0.022 SPEED Wire in Nickel Titanium to finalize torque correction and idealize archform. 0.018 x 0.018 Stainless Steel D Wire with reverse curve of Spee was then placed to complete bite opening, followed by 0.017 x 0.022 SPEED Wire in Stainless Steel to finish.
