Long-term follow-up of implant-stabilised overdentures.
The aim of this retrospective study was to assess the long-term outcome of patients provided with implant-stabilised overdentures. Patients who had been entered into a previous trial were identified; the records were available for nineteen patients restored with conventional complete upper dentures and implant-stabilised lower overdentures. The mean follow-up period was 11.5 years (range 5.25-13.5 years). One implant was lost and all patients have successfully worn their prostheses, although most have experienced problems: loosening, loss and fracture of retaining clips, soft tissue complications and fractured bars. Nine patients subsequently had bars replaced with ball attachments. This conversion significantly reduced requirements for maintenance and professional care. Implant-stabilised lower overdentures supported on two implants provide a simple, predictable solution for patients with otherwise poorly retained and unstable lower dentures.
