Fig. 2From: A 3-year prospective randomized clinical trial of alveolar bone crest response and clinical parameters through 1, 2, and 3 years of clinical function of implants placed 4 months after alveolar ridge preservation using two different allogeneic bone-grafting materialsa–h This figure demonstrates the measurement technique at the mesial (ABC-M) and the distal (ABC-D) aspects of the alveolar crest throughout the observational period between T1 (a following tooth extraction)–T8 (h 3 years following restoration) for a bone-level implantBack to article page
