Implant-retained overdentures, Attachment systems, Implant survival, Retention, Stress distribution, Complications, Patient satisfaction


Implant-retained overdentures have revolutionized dental prosthetics, addressing the limitations of traditional removable dentures. These overdentures rely on attachment systems to anchor them to dental implants or abutments, improving stability, retention, and functionality. Common attachment systems include locator attachments, bar attachments, magnets, Hader clips, ERA attachments, telescopic crowns, and OT equator attachments. Each offers unique benefits and retention levels. Implant survival rates are influenced by various factors, including attachment type, but overall, attachment choice may not be the primary determinant of implant success. Attachment systems that evenly distribute forces, like bar attachments, contribute to implant stability. Marginal bone loss can affect implant stability and is influenced by attachment systems. Precision attachments, such as telescopic crowns, have shown reduced marginal bone loss in practice. Soft tissue complications, including inflammation and mucositis, vary by attachment but can be managed with proper oral hygiene. Retention, crucial for function, varies with attachment type and implant number. More implants generally improve retention, although it may decrease over time. Bar attachments typically provide superior retention. Maintenance is essential, with some debate over whether bar or stud designs entail more upkeep. Patient satisfaction is high with both bar and ball attachments, while magnets may pose retention issues. The choice of attachment depends on patient needs and clinical factors, with regular follow-up and maintenance essential for long-term success.
