Fig. 2From: Evaluation of dimensional behavior of peri-implant tissues in implants immediately exposed or submerged in fresh extraction and healed sites: a histological study in dogsParameters measured in each group. Crestal bone loss is the distance between the implant collar (A) and the first bone contact of the crestal bone (B) = A-B bone height; and, the tissue thickness that is the distance from the implant collar (C) to the more external portion of the tissues (D) = C-D tissue thickness.
