An update on attachment systems for mandibular implant overdentures: A review

The present systematic review aims to evaluate the global use of attachment systems for mandibular implant overdentures, focusing on their impact on clinical outcomes, patient satisfaction and prosthesis stability. Mandibular overdentures supported by implants have become a standard of care for edentulous patients, with various attachment systems such as bar, ball and locators being commonly utilized. The review synthesizes findings from numerous studies, examining differences in retention, ease of maintenance, cost-effectiveness and long-term success rates across different attachment modalities. The analysis also delves into patient-centered outcomes, including comfort, ease of use and quality of life, providing a comprehensive overview of the efficacy of each system. By comparing and contrasting these systems, the review identifies trends and preferences in clinical practice, highlighting the benefits and drawbacks of each approach. The findings indicate that while all systems show promise in enhancing the functionality of mandibular overdentures, patient-specific factors and clinician preferences play crucial roles in the selection process.
