All-on-4 and All-on-6 Dental Implants: Treatment, Benefits and Differences
All-on-4 and All-on-6 dental implants are full-arch tooth replacement treatments designed for people who have lost most or all of their teeth. Instead of using a separate implant for every missing tooth, these treatments use four or six strategically positioned dental implants to support a fixed full-arch bridge.
Both options can restore chewing function, improve the appearance of the smile and provide greater stability than conventional removable dentures. However, the most appropriate treatment depends on the patient’s oral health, bone structure, bite and individual clinical needs.
At Agagsia Dental Clinic, each full-mouth dental implant treatment begins with a detailed assessment and personalised planning process.
What Are All-on-4 Dental Implants?
All-on-4 dental implants use four implants to support a complete fixed bridge in the upper or lower jaw. Typically, two implants are placed towards the front of the jaw and two towards the back. The rear implants may be angled to make effective use of the available bone and provide support for the prosthesis.
This approach may reduce the need for bone grafting in some patients, but it does not eliminate it in every case. Bone volume, bone quality and implant position must be evaluated using clinical examination and appropriate imaging.
All-on-4 treatment may be suitable for patients who:
• Have lost all or most of their teeth in one or both jaws
• Have several failing, severely damaged or untreatable teeth
• Find removable dentures uncomfortable or unstable
• Want a fixed full-arch tooth replacement
• Have sufficient bone and appropriate general health for implant surgery
What Are All-on-6 Dental Implants?
All-on-6 dental implants use six implants to support a fixed full-arch bridge. The additional implants can offer more support and help distribute biting forces across a wider area when the patient’s anatomy allows.
All-on-6 treatment may be considered when there is adequate bone to place six implants safely and when the dentist believes that the additional support would benefit the planned restoration. It is not automatically better than All-on-4; the right number and position of implants must be determined for each patient.
All-on-4 vs All-on-6 Dental Implants
The primary difference between All-on-4 and All-on-6 is the number of implants supporting the dental bridge. Other differences depend on the patient’s anatomy and treatment plan.
Benefits of Full-Arch Dental Implants
Potential benefits of All-on-4 and All-on-6 dental implant treatment include:
• A fixed alternative to removable dentures
• Improved stability when speaking and eating
• A smile designed to complement the patient’s facial proportions
• Fewer implants than replacing every missing tooth individually
• Support for the jawbone in the areas where implants are placed
• Easier daily use without denture adhesives
• The possibility of receiving fixed temporary teeth shortly after surgery in suitable cases
Treatment results and timescales vary. Immediate temporary teeth cannot be guaranteed and depend on implant stability, bone quality, bite forces and the dentist’s clinical assessment.
Who May Be Suitable for All-on-4 or All-on-6 Treatment?
Full-arch dental implants may be considered for adults who have extensive tooth loss, advanced dental damage or uncomfortable removable dentures. Suitable candidates generally need healthy or manageable gum tissue, adequate bone or an appropriate bone-management plan, and general health that supports healing after surgery.
Factors that may affect suitability include:
• Active gum disease or untreated dental infection
• Insufficient bone volume
• Uncontrolled diabetes or certain medical conditions
• Smoking or nicotine use
• Severe teeth grinding or clenching
• Medicines or treatments that affect bone healing
• Difficulty maintaining oral hygiene
These factors do not always prevent implant treatment, but they may increase risk or require additional preparation. Patients should provide a complete medical history during their consultation.
The All-on-4 and All-on-6 Treatment Process
1. Consultation and Diagnostic Assessment
The process begins with an examination of the teeth, gums, bite and jaw. Dental X-rays and usually a three-dimensional CBCT scan are used to assess bone quantity, bone quality and important anatomical structures.
The dentist then discusses whether All-on-4, All-on-6 or another treatment would be the most appropriate option.
2. Digital Treatment Planning
Implant positions and the proposed restoration are planned according to the patient’s anatomy and prosthetic requirements. Digital scans, photographs and bite records may be used to design the new smile and support accurate implant placement.
3. Tooth Extraction and Implant Placement
Any teeth that cannot be preserved may be removed before or during implant surgery. Four or six dental implants are then placed in the planned positions.
Treatment is commonly performed using local anaesthetic. Sedation or other anaesthetic options may be available when clinically appropriate, depending on the provider, patient and complexity of the procedure.
4. Temporary Fixed Teeth
When the implants achieve sufficient initial stability, a temporary fixed bridge may be attached on the same day or shortly afterwards. This is sometimes described as “same-day teeth” or “teeth in a day”.
The temporary bridge is designed for the healing period and must be protected with a dentist-approved soft diet. It is not the final restoration.
5. Healing and Osseointegration
During healing, the jawbone gradually integrates with the implant surfaces. This process usually takes several months. Regular follow-up appointments allow the dental team to check healing, hygiene and the condition of the temporary bridge.
6. Final Full-Arch Bridge
After successful healing, new scans or impressions are taken to produce the final fixed bridge. Its fit, bite, speech, appearance and ease of cleaning should be checked before completion.
How Long Do All-on-4 and All-on-6 Implants Last?
There is no guaranteed lifespan for All-on-4 or All-on-6 dental implants. With careful planning, good oral hygiene and regular professional maintenance, implants and full-arch restorations can remain functional for many years.
The implants and the bridge are separate components. Even when the implants remain healthy, the bridge, screws or individual components may eventually require maintenance, repair or replacement.
Long-term outcomes can be affected by:
• Oral hygiene and professional implant maintenance
• Smoking and nicotine use
• Gum health
• Diabetes control and general health
• Teeth grinding or excessive bite forces
• The quality and quantity of jawbone
• The fit and design of the restoration
• Attendance at scheduled dental examinations
Recovery After Full-Mouth Dental Implant Treatment
Swelling, bruising, tenderness and minor bleeding can occur after implant surgery. These effects commonly improve during the initial recovery period, although every patient heals differently.
Patients should follow their dentist’s instructions regarding prescribed medication, oral hygiene and food. A soft diet is normally necessary while the implants heal and while wearing a temporary bridge. Returning immediately to hard or chewy foods can place excessive pressure on the implants.
Contact the dental team promptly if pain or swelling becomes worse rather than better, bleeding cannot be controlled, the temporary bridge feels loose or there are signs of infection.
What Can You Eat After All-on-4 or All-on-6 Surgery?
During the early healing period, suitable foods may include:
• Smooth soups that are not excessively hot
• Yoghurt and soft dairy products
• Mashed vegetables
• Scrambled eggs
• Soft fish
• Oats and porridge
• Well-cooked pasta
• Soft tofu and hummus
Hard, crunchy, sticky and chewy foods should be avoided until the dentist confirms that the implants and restoration can tolerate greater pressure. Biting directly into hard foods, including whole apples, should not be attempted during early healing.
How to Clean All-on-4 and All-on-6 Dental Implants
Daily cleaning is essential for protecting the gum tissue and supporting the long-term health of the implants. Patients may be advised to use:
• A soft manual or electric toothbrush
• Low-abrasion toothpaste recommended by the dental team
• Implant floss, super floss or interdental brushes
• An oral irrigator where appropriate
• Any additional products prescribed by the dentist or hygienist
The area beneath the full-arch bridge must be cleaned carefully every day. Professional implant maintenance appointments are also necessary, even though the replacement teeth cannot develop decay.
Possible Risks and Complications
All-on-4 and All-on-6 are surgical treatments and carry potential risks. These can include infection, bleeding, temporary swelling, altered sensation, implant failure, gum inflammation, bone loss, loosening or fracture of prosthetic components, and the need for further treatment.
No responsible clinic can guarantee implant success. Individual risk depends on oral health, medical history, habits, bone conditions, treatment planning and aftercare. These issues should be discussed during the consent process.
