Table 1 Shows the significant and not-significant changes (p-value) in the mesial, distal, bucco-lingual, buccal, and oral dimensions of the alveolar ridge (ABC-M, ABC-D, ABC-BL, ABC-B, and ABC-O) in relation to the different time points (T1–T8)

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
