Objective: The functional, esthetic, and psychological problems of 3–6 months of edentulousness and also discomfort of two‐stage surgery might cause many patients to avoid implant‐supported restorations. Therefore, the immediate non‐functional loading protocol might be of value. Methods: Twenty Astra Tech implants, 11–13 mm in length and 3.5–4 mm in diameter, were placed in maxillary and mandibular posterior sites of 10 healthy patients (two for each) with adequate alveolar bone. Temporary prostheses were relieved of all centric and eccentric contacts. Functional permanent prostheses were fabricated 13 weeks postoperatively. Clinical and radiographic examinations (including the implant stability quotient [ISQ]) were carried out immediately after implantation and 3, 6, and 12 months postoperatively. Results: A 100% success rate was observed within 1 year. The plaque and bleeding indices, and pocket‐probing depths did not show a significant change throughout the study. The ISQ values after implant insertion, and 3, 6, and 12 months later were respectively 76.6 ± 6.57, 77.6 ± 10.54, 81.8 ± 6.8, and 82.43 ± 3.7. The increase was statistically significant ( P =0.004) according to the Freidman test. The ISQ values measured after the implant insertion were significantly different from those measured in the sixth and 12th postoperative months ( P <0.008) according to the Wilcoxon signed‐ranks test. The mean crestal alveolar bone resorption values in the third, sixth, and 12th postoperative months were 0.4 ± 0.55, 0.48 ± 0.37, and 0.48 ± 0.21 mm, respectively; and the change in marginal alveolar bone loss was not significant according to the Freidman test. Conclusion: Within the limitations of this pilot study, non‐functional immediate loading might meet the expectations of both the patients and clinicians. To cite this article:
