Changes in BH in 30 implants. The mean BH immediately after surgery was 3.16 ± 0.97 (1.2–5.5) mm, while the mean BH at follow-up was 0.25 ± 1.19 (− 2.58–3.00) mm; a mean decrease of 3.42 ± 1.43 (0.50–6.80) mm. After surgery, the maxillary sinus floor was below the implant apex (BH < 0) in 13 of 30 implants. BH, augmented bone above apex of the implant
