Abstract: This clinical case series highlights an under-reported and often unidentified complication of implant-retained overdentures that may leave patients with a risk of long-term discomfort and preventable damage to the opposing dentition. A variety of cases is discussed to demonstrate potential problems and symptoms that can flag up signs of parafunctional habits in implant patients, and how these can be managed successfully.

Clinical relevance: Implant-retained overdentures provide a significant improvement in quality of life; however, careful patient assessment and management is essential to ensure the components do not cause damage to the opposing dentition.
