Patients with resorbed edentulous upper jaws were arranged into 2 different groups, based on an overall assessment of bone resorption prior to implant surgery. Each group comprised 3.5 patients, all of whom received an overdenture after abutment connection. The patients in the group with the best bone situation were scheduled to receive a fixed prosthesis after 1 year provided that the clinical situation was stable. The overall cumulative implant and prosthesis treatment success rates were 77% and 85%, respectively, for a 3‐year follow‐up period. Nineteen of the patients in the best bone group received a fixed prosthesis after they had used the overdenture for 1 year. These patients exhibited a cumulative implant success rate of 97%. None of the fixed prostheses was lost. Implant failures and other clinical adjustments were frequent for the first year of follow‐up, but the number of problems diminished in the subsequent years.
