Implant-Supported Dentures: How They Work and Who They Suit

A conventional denture sits on the gum and relies on suction and fit. The jawbone underneath keeps shrinking over the years, so the denture loosens and needs relining. The lower jaw is worse than the upper because there is no palate to seal against and the tongue pushes the denture off.

In an implant-supported denture, usually called an overdenture, two to four implants are placed in the jaw and the denture has fittings that snap onto them. It still comes out for cleaning and sleep, but it stays put when you eat and talk. The implants also keep loading the bone, which slows its shrinkage.

A lower overdenture is commonly held by two implants, and often more where bone is poor or the bite is heavy. An upper overdenture usually needs more, because upper bone is softer and the denture covers a wider area.

The fittings come in two broad kinds. Ball or locator-style attachments are small, easy to clean and easy to replace when they wear. A bar joins the implants together under the denture and gives more retention, but it needs closer cleaning under it. Wear on the small plastic parts is expected and they are replaced at maintenance visits.

A fixed, full-arch bridge on implants is a different option. It is screwed in and does not come out at home, and it needs more implants and costs more. It is covered in All-on-4 dental implants.

An overdenture is easier to clean, cheaper, and easier to repair. It suits someone who is happy to keep taking a denture out. If your main complaint is a lower denture that moves, it is a good first thing to ask about. The missing teeth page puts it alongside the other replacement options.

It suits people who already wear a complete denture and cannot get comfortable with it, who struggle to eat, or who are tired of adhesive. It needs enough bone to hold implants and healthy gums, and diabetes, smoking and gum disease need to be under control.

It is a poorer fit if someone cannot clean a removable denture and implants reliably, or if surgery is unsafe for medical reasons. The comparison with the alternatives is in dental implants vs dentures.

In Lucknow in 2026, an implant-supported overdenture runs ₹80,000 to ₹2,00,000 per arch, depending on the number of implants and the denture quality. The full breakdown is on the dentures cost page.

Expect to clean the implants and attachments daily, to remove the denture at night, and to attend maintenance visits for check-ups and replacement of worn fittings. The denture base may still need relining as the gum changes. See how to clean dentures for the daily routine.
