For patients who are missing all of the teeth in an arch, a traditional complete denture can restore appearance and basic function. However, some patients struggle with movement, reduced chewing efficiency, or difficulty keeping the denture stable—particularly with a lower denture.
An implant overdenture uses dental implants to provide additional retention and stability for a removable denture.
At John E. Sullivan DDS, P.C., implant overdenture treatment is planned around the patient’s anatomy, bone availability, bite, existing denture condition, oral hygiene, and long-term functional needs.
Unlike a conventional denture that relies primarily on the gums and underlying jawbone for support, an implant overdenture connects to implants placed in the jaw. The denture remains removable by the patient for cleaning, but it can attach to the implants using specialized components that help resist movement during speaking and chewing.
Depending on the individual case, implant overdentures may be supported by individual attachment systems or by a bar connecting multiple implants.
Potential advantages can include improved:
Implants may also help preserve bone in the areas where they are placed by continuing to transmit functional forces to the surrounding jawbone. However, normal age-related and tooth-loss-related changes can still occur in other areas of the ridge.
Treatment typically begins with a comprehensive examination and appropriate imaging. 3D CBCT imaging may be used to evaluate available bone and important anatomical structures before implant placement.
The process may include:
In some cases, bone grafting or other preparatory treatment may be necessary before implants can be placed.
The lower jaw is one of the most common locations for implant overdenture treatment because conventional lower dentures can be especially difficult to stabilize.
For appropriately selected patients, even a relatively small number of implants can substantially improve the retention of a mandibular denture.
The appropriate number and location of implants depends upon the patient’s bone, anatomy, prosthetic design, bite forces, and overall treatment goals.
Implant overdentures require ongoing care.
Although dental implants cannot develop cavities, plaque and inflammation can develop around the implants and attachment components. Patients must clean around the implants carefully and remove the overdenture regularly for hygiene.
The attachment components within the denture are also subject to normal wear and may periodically need to be replaced or adjusted as retention changes.
The denture itself may eventually require relining, repair, or replacement as the oral tissues and jawbone change over time.
At John E. Sullivan DDS, P.C., our goal is to create an implant overdenture that improves stability and function while remaining practical for the patient to clean and maintain over the long term.
For the website link, I would probably call this service “Implant-Supported Dentures” rather than “Dental Implant Overdenture.” It is more immediately understandable to patients, while the page itself can explain that the technical term is an implant overdenture.
