Background: Recently, the present team reported the 1-year data of a one-stage surgery and mainly early loading with five supporting implants in completely edentulous mandibles, indicating more bone loss at the central implant, placed in the midline of the jaw. Purpose: The aim of the present retrospective investigation was to evaluate the 1-year results of the same treatment technique with four instead of five supporting implants in completely edentulous mandibles. The outcome was compared with that of a former study (control) on five implants per patient during first year of function. Materials and Methods: The present study comprised 75 patients with a total of 300 TiUnite™ implants (Nobel Biocare AB, Göteborg, Sweden) of mainly the Brånemark System ≥ Mark III design. The prosthetic procedure started and was completed on an average of 9.1 days (standard deviation [SD] 4.47) and 33.2 days (SD 16.09) after the surgical intervention, respectively. Intraoral radiographs were obtained at prosthesis insertion and at the 1-year follow-up visit. Failure rates of test and control groups were compared by means of the chi-squared test. Results: All four implants in one patient were found to be mobile at the first annual check-up, resulting in an implant cumulative survival rate (CSR) of 98.5%. The corresponding CSR for the control group was 100% (p > 0.05). The mean marginal bone resorption during the first year of function was 0.3 mm (SD 0.74) as compared with 0.5 (SD 0.56) mm for the control group (p > 0.05). Conclusions: The outcome of 300 TiUnite™ implants placed in 75 patients with edentulous mandibles, of which 268 implants in 67 patients were followed for 1 year, showed an implant CSR of 98.5%. The implant survival was not significantly different from that of the control study result of 100%, in which five instead of four supporting implants were used. The levels of marginal bone were close to identical for the corresponding test and control implants at the 1-year check-up.
