Background: The immediate loading of implants with a porous anodized surface is a well‐described technique. Few data are however available on the long‐term outcomes. Purpose: The aim of this prospective study was to assess the 10‐year performance of TiUnite implants supporting fixed prostheses placed with an immediate loading approach in both postextractive and healed sites. Materials and Methods: All patients received a fixed provisional restoration supported by immediately loaded parallel design, self‐tapping implants with a porous anodized TiUnite surface, and an external‐hexagonal connection. Both healed and postextractive cases were included. Success and survival rate for restorations and implants, changes in marginal peri‐implant bone level, probing depth measurements, biological or technical complications, and any other adverse event were recorded at yearly follow‐up up to 10 years after surgery. Results: A total of 210 implants fulfilled the inclusion criteria and were consecutively placed in 59 patients. Forty‐seven (22.38%) implants were lost because of the recalled patient refused to attend the planned 10‐year follow‐up. Five over 210 (2.38%) implants were lost. At the final follow‐up, the accumulated mean marginal bone loss and probing depth were, respectively, 1.93 mm (SD 0.40) and 2.54 mm (SD 0.44) for the implants placed in healed sites ( n = 84); 1.98 mm (SD 0.37) and 2.63 mm (SD 0.39) for the implants placed in postextractive sites ( n = 74). The restorations examined achieved a cumulative 65.26% success rate and 97.96% survival rate. The implants placed in healed and postextractive sites, respectively, achieved a 98.05% and a 96.52% cumulative survival rate. Conclusions: Positive results in terms of bone maintenance in the long‐term perspective are to be expected using immediately loaded implants with a TiUnite porous anodized surface in both postextractive and healed sites when adequate levels of oral hygiene are kept.
