Cases of mandibular first molar loss are common and their treatment often requires space gain for implant placement. In order to prevent the side effect of second premolar mesial rotation, we make a loop with an elastomeric chain in the archwire on the mesial surface of the canine. We then make the elastomeric chain go under the contact and place lingual pads on the lingual surface of the canine, first premolar and second premolar (whenever present), with the aid of a needle holder (Figs 1A to 1I). The advantage of this mechanics is that elastomeric chain forces are neutralized on the arch without side effects. The example reported herein shows a case of space gain for a mandibular left second premolar.
