What is an overdenture?

An overdenture combines features of traditional removable dentures and implant dentistry. Rather than resting solely on the gum ridge like a conventional denture, an overdenture clips onto dental implants placed in the jawbone. Typically two to four implants anchor the denture through bar attachments, ball attachments, or magnetic systems that create a secure connection without the denture being permanently fixed.

The patient can remove the overdenture for cleaning and care, which many people prefer to fixed restorations. However, because it sits on implants instead of soft tissue alone, an overdenture offers significantly better stability, retention, and chewing function than a traditional denture. Food does not trap beneath it as easily, and the implant support prevents the denture from shifting during eating or speaking.

Overdentures are distinct from fixed full-arch restorations, which are permanently attached to implants and cannot be removed by the patient. For patients who need a full-arch replacement but value the ability to remove their prosthetic for maintenance, an overdenture provides a practical middle ground. The implants must be healthy and properly positioned, and patients need adequate bone volume to support the implant placement.
