By the end of this guide, you will have a clear understanding of whether overdentures are the right solution for you.
What Are Overdentures?
Overdentures are a type of removable denture designed to fit over either dental implants or natural tooth roots. Unlike traditional dentures, which rest solely on the gums and rely on suction or adhesives for retention, overdentures have secure attachment points that provide a stronger, more stable fit.
How Do Overdentures Work?
The overdenture consists of a custom-fitted prosthetic arch designed to look and function like natural teeth. It is secured using:
- Dental implants: Titanium screws placed in the jawbone that act as artificial tooth roots, providing exceptional stability.
- Tooth roots: If a patient has remaining healthy teeth, they can be modified and capped to serve as support for the overdenture.
This structure ensures that overdentures remain firmly in place while still being removable for cleaning and maintenance.
Types of Overdentures
Overdentures come in two main types: overdentures that are implant-supported and tooth-supported overdentures. The choice depends on the patient’s oral health, bone structure, and personal preference.
Implant-Supported Overdentures
Implant-supported overdentures are secured onto two to six dental implants that are surgically placed into the jawbone. These implants provide a solid foundation, preventing the denture from shifting or moving.
Key Features
- Typically placed in either the upper or lower jaw.
- Can be fixed (permanent) or removable.
- Helps prevent jawbone shrinkage by stimulating bone growth.
- Eliminates the need for denture adhesives.
- Provides better chewing efficiency than traditional dentures.
Treatment Process
- Initial Consultation: The dentist evaluates the patient’s oral health, takes X-rays, and determines if the jawbone is strong enough to support implants.
- Implant Placement Surgery: Under sedation or local anaesthesia, tiny titanium pegs are surgically placed into the jaw.
- Healing and Integration: Over three to six months, the implants fuse with the bone in a process called osseointegration.
- Overdenture Fitting: A custom overdenture is designed and securely attached to the implants.
- Final Adjustments: The dentist ensures a comfortable fit, and the patient receives instructions on how to care for the overdenture.
Tooth-Supported Overdentures
If a patient has some remaining healthy teeth, these can be used as anchors for the overdenture instead of implants. The natural teeth are reshaped and fitted with protective caps or attachments to secure the denture in place.
Key Features
- Utilises existing natural teeth, which helps preserve bone structure.
- Requires less invasive treatment compared to implant-supported options.
- Still provides better retention than traditional dentures.
- Offers a more affordable option for patients who are not candidates for implants.
Treatment Process
- Dental Examination: The dentist assesses whether the remaining teeth are strong enough to support the overdenture.
- Tooth Modification: The selected teeth are reshaped and covered with small metal or gold copings to act as support pillars.
- Denture Fabrication: A custom overdenture is crafted to fit over these teeth securely.
- Final Fitting and Adjustments: The overdenture is fitted, and any necessary modifications are made for comfort.
Benefits of Overdentures vs Traditional Dentures
Overdentures provide several advantages over standard dentures, making them a preferred solution for many patients.
1. Improved Stability and Comfort
Because overdentures are anchored to implants or natural teeth, they remain secure in the mouth without slipping or moving while talking or eating.
2. Enhanced Chewing Ability
Traditional dentures often limit a person’s ability to eat harder or chewy foods. Overdentures restore a stronger bite force, allowing patients to enjoy a more varied diet.
3. Jawbone Preservation
By stimulating the jawbone, dental implants can stop the face drooping and shrinking, which happens when teeth fall out. This helps maintain a more youthful facial structure.
4. No Need for Adhesives
Many denture wearers find adhesives messy and inconvenient. Overdentures eliminate the need for pastes or glues, making daily wear hassle-free.
5. Reduced Gum Irritation
Standard dentures rest directly on the gums, often causing soreness and discomfort. Overdentures distribute pressure more evenly, reducing irritation.
Overdentures vs Traditional Dentures: Key Differences
| Feature | Overdentures | Traditional Dentures |
| Stability | Secured to implants or teeth | Rests on gums, may slip |
| Chewing Power | Stronger, more natural | Limited bite strength |
| Bone Health | Preserves jawbone | No stimulation, leads to bone loss |
| Comfort | More secure, better fit | May cause sore spots |
| Adhesives | Not required | Often needed |
How Much Do Overdentures Cost in the UK?
The cost of overdentures varies depending on the type of treatment, number of implants, and materials used.
NHS vs Private Treatment
- NHS funding for overdentures is limited. Basic dentures may be available under Band 3 treatment (£306.80 in England), but implant-supported overdentures are generally only available privately.
- Private clinics offer a greater range of materials, customisation, and long-term benefits.
Who Is a Good Candidate for Overdentures?
Overdentures may be suitable for:
- Patients who have lost multiple teeth and want a more stable alternative to traditional dentures.
- Individuals with enough jawbone to support implants.
- Those with some remaining natural teeth that can be used as support.
- People experience discomfort or difficulty with conventional dentures.
Overdentures may not be suitable for:
- Patients with severe jawbone loss, unless a bone graft is performed.
- Those with untreated gum disease or infections.
- Heavy smokers or individuals with certain medical conditions that affect healing.
