Bone window dimensions and bone height of five aspects of implants. a Bone window dimensions. b–f Bone height and analysis at T0, T1 and T2. *** P < 0.01, ** P < 0.05. T0, immediately after bone grafting; T1, before second-stage surgery; T2, last follow-up visit. BH, distance between implant platform and uppermost level of bone graft within sinus cavity. BH was measured at five aspects of each implant: central (BHC), mesial (BHM), and distal (BHD), buccal (BHB), and palatal (BHP) aspects
