Immediate Function of Anodically Oxidized Surface Implants (TiUnite™) for Fixed Prosthetic Rehabilitation: Retrospective Study with 10 Years of Follow-Up

Purpose. To report the long-term outcome at 10 years of fixed prosthetic rehabilitation supported by dental implants with anodically oxidized surfaces in immediate function. Materials and Methods. This retrospective cohort study included 75 consecutive patients (44 females and 31 males; 14 bruxers; 21 smokers; 14 systemic compromised), with average age of 60 years, rehabilitated with 264 implants. Outcome measures were implant cumulative survival rates (calculated through life tables) and marginal bone level at 10 years. Results. Twenty-one patients with 66 implants (25%) were lost to follow-up. Six patients lost 12 implants (MkIII implants: n = 9; MkIV implants: n = 3). The overall implant cumulative survival rate at 10 years was 95.2% (maxilla: 95.6%; mandible: 94.7%). The average (standard deviation) marginal bone level at 10 years was 1.96 mm (1.50 mm), with 1.92 mm (1.31 mm) for the maxilla and 2.00 mm (1.71 mm) for the mandible, with a significant difference between nonsmokers (average = 1.60 mm) and smokers (average = 2.95 mm). Conclusions. Within the limitations of this study, it can be concluded that fixed prosthetic rehabilitation supported by implants with anodically oxidized surface in immediate function is a viable and safe treatment option for both jaws.
