This study proposed a surgical technique that solves three-dimensional conditions of extreme bone atrophy. A total of 278 surgeries with transcrestal sinus lift and fresh frozen allogenous bone blocks were performed. A total of 1,024 implants were placed. After 60 months of observation, 969 implants were considered grade I (successful), 24 grade II (satisfactory survival), and 8 grade III (compromised survival). The cumulative success and survival rates, respectively, were 94.6% and 97.7%. This innovative procedure is very effective in selected cases. Fresh-frozen human bone allografts have been shown to be a reliable biomaterial to increase bone volume with simultaneous dental implant placement.
