Fig. 2 Fig. 3 bite turbos on the U4s, I also gave them a Class II ramp shape (the ramps sloped down and back) so that they contacted the distal of the L4s but did not touch the L5s (Fig. 5). For those interested, check out my December 2022 column on Class II ramps. In this manner, occlusal forces on the U4s and L4s could be partially redirected in an AP direction (slight distal force U4s and slight mesial force L4s). A side effect of the reliance on Class Fig. 4 II mechanics to fit the occlusion to the new vertical facial height was that it was very challenging to give proper torque to the upper incisors (which were already a bit deficient in positive labiolingual inclination pretreatment). In the end, the incisors finished still a bit under-torqued. Had I forced more positive torque into those teeth in finishing, however, this would have necessitated that the lower incisors be even further proclined to couple with the uppers. The lower incisors were already proclined because of the Class II elastics, so this further compromise was not deemed appropriate, given the thin lower anterior gingival phenotype. Additional notes There were other interesting findings during the 20 months of treatment. I initially chose a mild version of SAP bracket positioning in Lea's case. Her pre-treatment smile arc and vertical incisor display were reasonably acceptable since her maxillary incisors were in a slightly over-erupted position relative to the occlusal plane DECEMBER 2024 | 28 | ORTHOTOWN.COMhttp://www.ORTHOTOWN.COM
