Implant-Assisted Ortho
Five months post implant placement, a provisional is fabricated at LR4 as an anchorage to mesialize LR5, which also rotates (Fig.4 *). A space (Fig.1 *) is reserved for LR3 distalization (arrow) and anterior de-crowding (Fig.2,5).
Another absolute anchorage is at LL5 (Fig.5) for distalization of the anterior teeth so that there is no need for an implant at LL4.
When the tooth #29 is uprighted in 2 months, it develops severe pain in spite of occlusal reduction. It is finally extracted with immediate implant.
