Fig. 46 Fig. 49 Fig. 50 Fig. 47 Fig. 48 Fig. 51 Clinically I have found that in cases where there is one half of a molar Class II discrepancy or less and the second molar has not yet erupted, Class II to Class I correction can be achieved by using tip-back mechanics. If the Class II discrepancy is greater than one half of a molar or if the second molar is erupted, I choose to employ other distaliza-tion mechanics (Fig. 31). When utilizing tip-back bend molar distalization mechanics it is necessary to extend the archwire 6-8 mm beyond the distal edge of the molar bracket so that the molar can distalize along the archwire.
