Implant-retained overdentures represent a treatment option for many patients unable to tolerate conventional dentures. They may be specifically indicated in patients with altered anatomy, neuromuscular disorders, a pronounced gag reflex or severe residual ridge resorption. This article discusses the different ways in which implant overdentures can be retained, outlines some of the clinical stages involved in planning and providing these prostheses, and highlights long-term maintenance requirements associated with implant-retained overdentures.
Clinical Relevance: Patients with implant-retained overdentures are likely to present in general dental practice. Practitioners should be aware of issues associated with the design, treatment planning and maintenance of these prostheses.
Article
An implant-retained overdenture is a removable dental prosthesis supported by the residual oral tissues and retained by dental implants. This concept has been successfully used for over 30 years.1 Implant-retained overdentures demonstrate improved retention and stability when compared to conventional dentures.2,3 Furthermore, implant-retained overdentures may reduce residual ridge resorption and improve chewing function, nutritional status, speech and patient confidence,2,4 This type of prosthesis should be considered in all patients unable to tolerate conventional dentures. They may be specifically indicated in patients with altered anatomy following surgery, neuromuscular disorders, a pronounced gag reflex or severe residual ridge resorption.
This review discusses the differing ways in which implant-retained overdentures can be retained, outlines some of the clinical stages involved in planning and providing these prostheses, and highlights the maintenance requirements associated with implant-retained overdentures.
