Predictability of Simultaneous Implant Placement in the Severely Atrophic Posterior Maxilla: A 9-Year Longitudinal Experience Study of 2,132 Implants Placed into 731 Human Sinus Grafts
Summary:
One-stage implant placement in the grafted maxillary sinus has traditionally been limited to
patients with at least 5 mm of residual bone to ensure complete implant stabilization. The aim of this
prospective study was to determine the long-term survival rates of implants with roughened surfaces
placed immediately into maxillary sinus grafts in patients with 1 to 5 mm of residual bone.
