Implant-Supported Overdentures: What They Are and How They Work


A loose or uncomfortable denture can lead to difficulties in eating and speaking as well as oral discomfort. This can be due to changes in your gums and jaw bone over time. Implant-supported overdentures are designed to fit snugly and comfortably in your mouth. A well-fitted implant-supported overdenture enhances comfort and functionality while improving your quality of life.
Implant-supported overdentures (also known as implant overdentures or snap-in dentures) represent a significant advancement in dental restoration, providing a comfortable and effective solution for individuals with missing teeth. Whether you’re facing tooth loss in the upper or lower jaw, these prosthetics offer a secure fit that traditional dentures cannot match.

Understanding Implant-Supported Overdentures

What Are Implant-Supported Overdentures?

Implant-supported overdentures are a type of dental prosthetics that combine the benefits of traditional dentures with the stability of dental implants. They are designed to attach to special implants placed in the jawbone, acting as secure anchors for the overdenture.

Key Differences Between Implant-Supported Overdentures and Traditional Dentures

Retention: Unlike traditional dentures that rely on adhesive or natural suction, implant-supported overdentures click into place over dental implants, significantly reducing the risk of movement.
Bone Preservation: Dental implants stimulate bone growth by mimicking tooth roots, thus preventing the jawbone deterioration commonly seen with conventional dentures.
Fit and Comfort: The precise anchoring to dental implants means implant-supported overdentures fit more snugly, reducing irritation and discomfort associated with loose-fitting traditional dentures.

How Dental Implants Ensure Stability and Prevent Slippage of Overdentures

Dental implants are titanium posts surgically placed into the jawbone, where they integrate with bone tissue through a process known as osseointegration. This fusion creates a strong foundation that prevents slippage and movement of the overdenture, ensuring comfort and reliability during daily activities like eating and speaking. The presence of these implants is pivotal in providing a secure fit that users can trust, eliminating common concerns about denture stability.

Benefits of Implant-Supported Overdentures

Implant-supported overdentures offer several advantages over conventional dentures:

Enhanced Stability: The attachment to dental implants ensures a stable fit, allowing you to speak, eat, and smile with confidence.
Improved Comfort: The elimination of denture movement reduces irritation and sore spots, providing increased comfort throughout the day.
Preserved Bone Health: Dental implants stimulate the jawbone, preventing bone loss that typically occurs when natural teeth are missing.
Restored Chewing Efficiency: With Implant-Supported Overdentures, you can enjoy a varied diet without restrictions, as they restore nearly 90% of your natural chewing ability.
Boosted Self-Esteem: The aesthetic appeal of Implant-Supported Overdentures enhances facial appearance and restores a youthful smile, boosting self-confidence.

Process for Getting Implant-Supported Overdentures

The process of obtaining implant-supported overdentures generally involves the following steps:

Initial Consultation: Your dentist will evaluate your oral health, review your medical history, and conduct imaging tests (such as X-rays or CT scans) to determine if you are a suitable candidate for dental implants.
Implant Placement Surgery: If deemed eligible, you will undergo a surgical procedure where titanium implants are inserted into your jawbone. The number of implants required will depend on your specific case.
Healing Period: After implant placement, a healing period of several months is necessary to allow osseointegration, the process by which the implants fuse with the jawbone.
Abutment Placement: Once the implants have integrated with the bone, abutments (connector pieces) are attached to them, which will later support the overdenture.
Impressions and Prosthesis Fabrication: Your dentist will take impressions of your mouth to create a custom-made overdenture that fits precisely over the implants and abutments.
Fitting and Adjustments: The final prosthesis is placed and adjusted as needed to ensure proper fit, bite alignment, and aesthetics.

Cost Considerations for Implant-Supported Overdentures

Investing in your dental health is a crucial aspect to consider. The treatment costs of an implant-supported overdenture are dependent on several factors: the number of implants, the type of prosthesis, and the need for any additional procedures such as extractions or bone grafts.
The cost range for implant-supported dentures starts from $4,500, inclusive of two implant fixtures with an acrylic denture. Though this may seem expensive at first, when you consider the long-lasting benefits and toughness of overdentures, this option can often seem more appealing.
Singaporean Residents have access to a beneficial scheme – Medisave. Under this, claims can be made up to $1,250 for the first implant and $950 for subsequent implants if done in the same surgery. This significantly reduces the out-of-pocket expenses involved in the procedure.
In addition to Medisave claims, subsidies are also available to further alleviate financial burdens. Eligible individuals holding CHAS/MG/PG cards can use these subsidies, making implant-supported overdentures an affordable dental solution.
It’s essential to discuss these cost considerations with your dentist during your initial consultation. A comprehensive breakdown of the costs will help you understand your investment better and allow you to plan accordingly.

Maintenance Tips for Implant-Supported Overdentures

To maximize the lifespan of your implant-supported overdentures and maintain good oral health, follow these guidelines:

⦁ Clean your overdentures daily using a soft-bristle toothbrush and non-abrasive denture cleaner.
⦁ Remove and rinse your overdentures after meals to remove any food particles.
⦁ Brush your gums, tongue, and palate with a soft toothbrush or gauze pad to stimulate circulation and remove plaque.
⦁ Visit your dentist regularly for check-ups and professional cleanings.
⦁ Avoid chewing on hard or sticky foods that could damage your overdentures.
