Objectives: The aim of this prospective comparative study was to evaluate the survival rate, condition of peri‐implant tissues, patient satisfaction and surgical and prosthetic aftercare of the IMZ‐implant system (two‐stage cylinder type), the Brånemark‐implant system (two‐stage screw type) and the ITI‐implant system (one‐stage screw type) supporting a mandibular overdenture during a 10‐year follow‐up period. Materials and Methods: Three groups of 30 edentulous patients were treated with two endosseous implants in the interforaminal region of the mandible. Clinical and radiographic parameters were evaluated immediately after completion of the prosthetic treatment and after 1, 5 and 10 years of functional loading. Prosthetic and surgical aftercare was scored during the evaluation period, as well as patient satisfaction. Results: The 10‐year survival rate was 93% for the IMZ group, 98% for the Brånemark group and 100% for the ITI group (IMZ
