a This figure shows changes in the measurements of the distance of alveolar bone crest (ABC) to the cemento-enemal junjction (CEJ) or the restorative margin (RM) for the mesial aspect by evaluation time [T1 (after tooth extraction), T2 (after ARP), T3 (4 months later at implant placement), T4 (4 months later at implant uncovery) and T5 (after implant restoration)] as well as at 1 (T5–T6), 2 (T5–T7), and 3 years (T5–T8) of clinical functioning compared by bone-grafting material. b This figure shows changes in the measurements of the distance of alveolar bone crest (ABC) to the cemento-enemal junjction (CEJ) or the restorative margin (RM) for the distal aspect by evaluation time [T1 (after tooth extraction), T2 (after ARP), T3 (4 months later at implant placement), T4 (4 months later at implant uncovery) and T5 (after implant restoration)] as well as at 1 (T5–T6), 2 (T5–T7), and 3 years (T5–T8) of clinical functioning compared by bone-grafting material. c This figure shows changes in the clinical measurement values for the bucco-lingual bone width (ABC-BL) by evaluation time [(T1 (after tooth extraction), T2 (after ARP), T3 (4 months later at implant placement), T4 (4 months later at implant uncovery)] by bone-grafting material. d This figure shows changes in the clinical measurement values for the buccal bone height (ABC-B) by evaluation time [(T1 (after tooth extraction), T2 (after ARP), T3 (4 months later at implant placement), T4 (4 months later at implant uncovery)] by bone-grafting material. e This figure shows changes in the clinical measurement values for the oral bone height (ABC-O) by evaluation time [(T1 (after tooth extraction), T2 (after ARP), T3 (4 months later at implant placement), T4 (4 months later at implant uncovery)] by bone-grafting material
