Modern Dentistry offers long-term solutions that can replace an entire upper arch, lower arch or even both. Full mouth dental implants can restore appearance, improve chewing ability, and provide a level of stability that traditional dentures simply cannot match.
If you are considering a full mouth restoration, understanding the different treatment options available is the first step towards making an informed decision.
What Are Full Mouth Dental Implants?
Full mouth dental implants are used to replace all the teeth in one or both jaws using strategically placed dental implants.
Instead of replacing every missing tooth with an individual implant, a smaller number of implants are used to support a full set of replacement teeth. This conservative approach allows patients to benefit from improved stability and function while reducing the number of implants required for a restoration.
Depending on your needs, this treatment may involve:
Fixed implant bridges
Implant-retained dentures
All-on-4 implants
All-on-6 implants
The most suitable option depends on factors such as bone levels, oral health, lifestyle, and budget.
What Is the All-on-4 Technique?
All-on-4 is one of the most widely recognised full arch implant treatments. This technique uses four dental implants to support a complete set of replacement teeth. It typically involves two implants placed vertically at the front of the jaw and two additional implants placed at an angle towards the back.
The angled implants help maximise the use of available bone and can often avoid the need for more extensive bone grafting procedures. Many patients can receive a fixed temporary bridge on the same day as implant placement, which is why the treatment is often known as “same day teeth”.
One important point to remember is that full-mouth treatment generally requires four implants in the lower arch and four implants in the upper arch when using the All-on-4 technique.
What Is the All-on-6 Technique?
As the name suggests, this technique is similar to the All-on-4 approach but uses six implants instead of four to support a full arch of teeth. These additional implants provide greater support and help distribute chewing forces more evenly across the jaw.
Some advantages of All-on-6 are:
Increased stability
Enhanced support for longer bridges
Improved load distribution
Potentially greater long-term resilience
However, not every patient requires six implants for a full restoration. The choice between All-on-4 and All-on-6 depends on individual anatomy, bone quality, and treatment objectives.
Fixed vs Removable Implant- Supported Teeth
One of the most important decisions involves choosing between fixed or removable restorations.
Fixed Implant Bridges
A fixed full-arch bridge is permanently attached to the implants and can only be removed by a dental professional. For many patients, this option feels closest to having natural teeth as some of their benefits include offering excellent stability, strong chewing function, and a natural appearance.
Many patients appreciate the confidence that comes with knowing that their teeth remain securely in place.
Removable Implant Dentures
Implant-retained dentures are designed to clip onto implants but can be removed by the patient for cleaning and maintenance.
They offer significantly more stability than conventional dentures, while remaining easier to maintain for some individuals. This option might be particularly suitable for patients seeking a more affordable alternative to a fixed bridge.
What Are Locator Buttons?
Locator attachments, often called locator buttons, are commonly used to secure removable implant dentures. They are small connectors attached to the implants that allow the denture to click securely into place over them.
This type of connection provides the following advantages:
Improved denture stability
Reduced movement
Easier eating and speaking
Simple removal for cleaning
While many patients find locator-retained dentures life-changing, you also need to consider that attachment components may require periodic replacement as they wear over time.
What Are Implant Bars?
An implant bar is another type of connection that consists of a custom-made metal framework attached to multiple implants, which allows the denture to clip onto the bar, providing excellent stability.
This type of connection provides better stability, stronger retention, and improved support, but is strictly dependent on prosthesis design and other anatomical factors.
Many patients find implant bars more secure than locator-retained dentures.
Who Is Suitable for Full Mouth Dental Implants?
Full mouth implant treatment may be suitable in the following situations:
If you have lost most or all of your teeth
If you wear full dentures and want a more durable and comfortable option
If you have teeth that cannot be saved
If you struggle with loose dentures
A detailed assessment is required to determine whether sufficient bone is available to support implants. However, even patients who have experienced bone loss may still be candidates following bone grafting or advanced implant planning.
What Does the Treatment Process Involve?
While every case is different, a full mouth dental implant process involves similar stages to any other dental implant.
Our team will carry out a complete clinical examination, digital scans, X-rays, and 3D CBCT imaging during your initial consultation.
With that information, our team can determine the optimal implant positions and prosthesis design.
The implants are placed into the jawbone under local anaesthetic, often using a 3D surgical guide to improve precision and accuracy.
A temporary prosthesis is placed over your implants on the same day or shortly after.
The implants gradually integrate with your jawbone over several months.
A final restoration is then fitted and secured in place.
