Case studies Case 1 Fig. 5 Fig. 7 Fig. 6 This 34-year-old aligner patient had a deep bite (Fig. 5), and several attempts to level her curve of Spee with Invisalign and Invisalign G5 innovations had failed. The decision was made to incorporate MOPs and HFV (Fig. 6). Seventeen more aligners with HFV for five minutes each evening finally solved a most tenacious deep bite (Fig. 7). Case 2 Fig. 8 Fig. 10 Fig. 9 This 25-year-old patient had a deep bite and wear on her lower anterior teeth, and several rounds of aligners with all of the recommended innovations had not solved the deep bite (Fig. 8). At nine months into treatment, with aligners losing tracking again (Fig. 9), the decision was made to incorporate MOPs and HFV. Three months later, the aligners were seating (Fig. 10), and the deep-bite correction was finally mobilized. orthotown.com \\ DECEMBER 2019 39http://www.orthotown.com
