After use of Magic Split and Expanders (until 3.8 mm for 13 mm), try 5 mm dummy implant (Fig.11). If 6 mm one fails to achieve stability substantially, switch to 7 mm Tatum tapered tap provided there is enough mesiodistal space (use 8 mm implant positioner to gauze the space beforehand (preop)). Consider using Vanilla (not Vera) Graft to fill in the gap between implant and osteotomy. When primary stability is obtained, place a nonfunctional provisional to prevent further shifting (Fig.11 white outline). After osteointegration, use the provisional (reline and separator) to distalize the tooth #15.
