A 5.5x4(4) mm cemented abutment is placed for impression. The patient returns with #18 crown dislodgement and #19 crown loosening 11 months post cementation (Fig.5 <: gap between implant and abutment). To reduce the chance of re-fracture of #18 crown, the tooth #15 needs to be distalized orthodontically so that an implant will be placed at #14 (Fig.5).
