Overdentures provide better stability, retention, and patient comfort compared to conventional complete dentures, representing a significant advancement in removable prosthodontics. Their effectiveness is strongly influenced by the type of support, whether tooth-supported or implant-supported, as well as the chosen attachment system, including ball-bar-clip locators, telescopic mechanisms, and magnetic mechanisms. Mandibular implant overdentures in particular demonstrate high clinical predictability and remain the standard of care for patients with severe ridge resorption. This review evaluates the performance of overdentures by examining implant survival, mechanical and biological complication patterns, functional outcomes, and patient satisfaction. According to available data, implant overdentures greatly improve oral health-related quality of life while increasing bite force and masticatory efficiency. Long-term success requires taking into account attachment-specific maintenance requirements, such as the wear of bar components or the periodic replacement of nylon inserts in locator systems. To achieve similar results, maxillary overdentures may need extra implants or changes to the palatal design. The review also covers emerging trends influencing overdenture therapy in the future, clinical implications, and maintenance procedures. Clinicians can choose the best attachment systems to predict maintenance needs and enhance long-term treatment outcomes for edentulous patients by having a thorough understanding of these factors.
