Further, due to the long-term edentulism and supraeruption of 16, the region was found to have compromised interocclusal space for prosthetic restoration [Figure 1].

The orthopantomograph suggests the area of edentulism with root stumps #46 with availability of sufficient bone height for implant placement in relation to 46 [Figure 2].

A Ni-Ti coil spring was passed through the occlusal surface of the maxillary first molar and both free ends of the coil spring were anchored to the mini-implant on the either side, thereby delivering a mild, continuous intrusive force of about 50 g to 70 g till the supraeruption was corrected, up to a period of 6 months [Figure 3].

An implant sized 4.5 mm x 13 mm (Myriad Plus implant system, Equinox Medical Technologies, Netherlands) was placed after the atraumatic extraction of root stump in relation to 46 [Figure 4].

The interocclusal space was reevaluated and found to be ~5 mm, which was adequate for the prosthetic rehabilitation of the dental implant #46 [Figure 5].
