• Biologic width is the mandatory distance to be left between the height of the alveolar bone and the margin of the restoration, and if this distance is violated because the margin is placed too subgingivally, serious repercussions may follow.
• Increased loss of inter-implant bone in the vertical dimension due to this overlap of horizontal components of the adjacent implants'biologic width can have ramifications in the anterior esthetic zone because it decreases bony support for the interproximal papilla between implants.
• Around implants, biologic width formation has classically led to about 1.5-2 mm of bone loss in the vertical dimension at the coronal aspect of the implants because the abutment that attaches to the implant was often removed many times to allow for impression taking, abutment changing and other related clinical functions.
