Objectives: To evaluate the survival rate of non‐submerged solid‐screw ITI dental implants with a rough (titanium plasma sprayed, TPS) surface in the edentulous maxilla after 1 and 2 years of loading. Material and method: Twenty‐five patients (mean age 64 years) with edentulous upper jaws received five–seven implants and, after a mean healing time of 6.9 months, screw‐retained implant‐supported fixed prostheses. A total of 146 ITI solid screw TPS implants were inserted . The diameter of 56% of the implants was smaller (3.3 mm) than the standard (4.1 mm) and the diameter of the rest (44%) was standard. The bone quantity of the majority of the patients was low and the bone quality poor. Clinical parameters were registered at baseline and at two annual follow‐ups. Radiological examinations and assessments were also made at these times. Results: Mean marginal bone level at baseline was measured at a point 4.52 mm (range 1.45–7.70, SD 1.2) apical of the reference point. Mean bone loss from baseline to 1 year of loading was 0.24 mm (SD 0.9, P =0.002) and from 1 year to 2 years of loading 0.15 mm (SD 0.4, P <0.001). Five implants failed, four of which were early failures prior to loading. One implant failed shortly after bridge installation. The cumulative survival rate was 96.6% after 1 and 2 years. Conclusion: ITI TPS solid‐screw implants in combination with fixed prostheses had successful survival rates and were found to be a viable treatment alternative in the edentulous maxilla.
