Implant‐prosthetic rehabilitation of the completely edentulous mandible has evolved to a simplified procedure with shorter treatment time and survival rates of 95–100% depending on the implant system used. Purpose: The aim was to evaluate the 3‐year clinical success of Astra Tech TiOblast implants, functionally loaded on the day of surgery with a fixed full‐arch bridge in the mandible. Materials and methods: One hundred and twenty‐five implants of 3.5–4 mm width and 11–17 mm length were installed in 25 edentulous mandibles of 15 female and 10 male patients. Implants were functionally loaded on the day of surgery with a provisional, acrylic, glassfibre reinforced, 10 unit bridge. After 3–4 months, the final 12‐unit bridge was constructed. Radiographical bone loss was measured on peri‐apical radiographs after 3, 12, 24 and 36 months. Results: All implants were functional during the whole study period yielding a survival rate of 100%. None of the fixtures showed pain or mobility after manual torque with 20 N cm at the 3‐month control. Mean radiographical bone loss after 3 months and 1, 2 and 3 years was 0.6 mm (SD 0.7), 0.8 mm (SD 0.8), 1 mm (SD 0.8) and 1.3 (SD 1) respectively, which was statistically significantly increasing up to 1 year. Conclusion: Immediate loading of full‐arch mandibular bridgework on five TiOblast implants offers a long‐lasting clinical result with 100% fixture survival and stable bone‐to‐implant contact up to 3 years.
