Overdenture
A removable denture stabilized by implants or remaining tooth roots — the comfort and confidence of teeth that stay put.
An overdenture sits between a conventional denture and a fixed bridge. It's still removable for cleaning, but instead of resting on the gums alone, it anchors to dental implants or remaining tooth roots underneath. The result is a prosthesis that stays where it belongs — quieter, more comfortable, and dramatically more efficient for chewing.
What an overdenture is
An overdenture is a removable denture that draws part of its retention and support from structures underneath it. Those structures can be either:
- Dental implants — the most common modern approach. Two to four implants are placed in the jawbone, and the denture clips, snaps, or seats onto attachments built into the implants.
- Remaining tooth roots — in select cases, a few healthy roots can be retained, shaped, and fitted with attachments that anchor the denture. This preserves the bone that would otherwise resorb after extraction.
Either way, the patient still removes the denture daily for cleaning. The difference is what happens when it's in the mouth: it doesn't rock, slip, or rely on adhesive to stay in place.
How it compares to other options
- vs. Conventional denture: An overdenture is dramatically more stable. Chewing efficiency improves significantly, especially for foods like meat, apples, and crusty bread. Many patients describe it as the difference between teeth that work and teeth that fight them.
- vs. Fixed implant bridge (All-on-4): A fixed bridge stays in the mouth permanently; an overdenture is removable. Overdentures typically require fewer implants, cost less, and are easier to clean around. Fixed bridges feel closest to natural teeth and are the right choice for many patients — but overdentures remain an excellent, more accessible option.
- vs. Doing nothing: Going without teeth (or wearing an ill-fitting denture) accelerates bone loss in the jaw, changes facial shape over time, and limits diet. Overdentures preserve bone around the supporting implants or roots and restore much of what is lost.
Restorative care from a prosthodontist
Overdenture cases have two phases when implants are involved: surgical and restorative. Dr. Rasmussen focuses on the restorative side. He plans the case from the final outcome backward — how the denture should look, where the implants need to sit to support it, what attachment system will be most reliable for your situation — and then coordinates with an oral surgeon or periodontist who places the implants to that plan. Once the implants have healed, Dr. Rasmussen designs, fits, and delivers the final overdenture.
Who is a candidate?
Overdentures are a strong option for patients who:
- Are missing most or all of the teeth in an arch.
- Currently wear a conventional denture that doesn't fit or function well.
- Want better stability than a regular denture, but are not pursuing a fixed full-arch reconstruction.
- Have enough jawbone to support a small number of implants (or can benefit from grafting).
- Are comfortable with a removable prosthesis for daily cleaning.
Candidacy is confirmed during a consultation that includes a clinical exam and, when implants are being considered, a cone-beam CT scan to evaluate the available bone.
The treatment timeline
- Consultation and planning. Exam, imaging, and a written treatment plan. The number and position of implants is determined by the final denture design.
- Implant placement (with the surgeon). Implants are placed by an oral surgeon or periodontist. A temporary prosthesis is worn during healing.
- Healing phase. Three to six months for the implants to integrate with the jawbone.
- Restorative phase. Dr. Rasmussen attaches the connecting components, takes impressions, and fabricates the final overdenture. The prosthesis is fitted, adjusted, and delivered.
Long-term care
An overdenture is removed daily for cleaning — the denture is brushed with a soft brush and mild soap or denture cleaner, and the implants or roots in the mouth are cleaned the same way you would clean natural teeth. The attachment components (clips, O-rings, or rubber inserts) are wear parts and are routinely replaced every one to two years to maintain a snug fit. The denture itself typically lasts seven to ten years before relining or replacement, with the supporting implants or roots lasting much longer.

Frequently Asked Questions
An overdenture is a removable denture that is anchored by either dental implants or remaining natural tooth roots. Unlike a conventional denture that rests entirely on the gums, an overdenture clips, snaps, or seats onto an underlying support structure for greater stability, retention, and chewing efficiency.
A conventional denture rests on the gums and is held in place by suction and the surrounding muscles. An overdenture is anchored to underlying implants or tooth roots, so it does not rock, slip, or rely on adhesive. Patients with overdentures typically report better chewing function, more comfort, and greater confidence than with conventional dentures.
Dr. Rasmussen does not place dental implants surgically. He plans the case, designs the overdenture and attachment system, and coordinates with an oral surgeon or periodontist who places the implants. He then completes the restorative phase and delivers the final overdenture.
With proper care, the prosthesis itself typically lasts seven to ten years before relining or replacement is needed. The attachment components (rubber inserts, clips, or O-rings) wear with use and are routinely replaced every one to two years as part of regular maintenance. The implants or roots that support the overdenture can last decades with good care.
