Table 2 Shows the radiographically detectable mean changes (mm) from the mesial (ABC-M) and distal (ABC-D) alveolar bone crest to the cemento-enamel junction (CEJ) or restorative margin (RM) between the different time points at T1–T2, T2–T3, T3–T4, T5–T6, at 1 (T5–T6), 2 (T5–T7), and 3 years (T5–T8) of clinical functioning as well as the clinically detectable mean changes of alveolar crest width (ABC-BL) and for alveolar bone crest height (ABC-B and ABC-O) for T1–T4 compared by bone-grafting material

From: 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 materials
