What Does All-on-4 Mean?
All-on-4 describes a full-arch treatment concept in which a fixed bridge is supported by four carefully placed implants. The back implants may be angled to use the available bone and avoid nearby anatomical structures.
People often use the name more broadly when looking for fixed full-mouth implant treatment. However, the number and position of implants should be based on the condition of your jaw, gums and bite—not a standard formula.

Who Could Full-Arch Implants Suit?
Treatment may be considered if you:
- Have many missing teeth
- Have badly failing teeth
- Wear loose dentures
- Want a fixed option
- Have suitable general health
Age alone does not determine suitability. Your gums, bone volume, medical history, smoking and ability to clean the bridge are more important.
An assessment with a specialist periodontist serving Wollongong can help determine whether you have a suitable foundation for treatment.
Why Your Teeth Were Lost Matters
Understanding why your natural teeth failed is essential. Many full-arch patients have experienced advanced periodontitis, which may also increase the risk of inflammation around implants.
Your assessment may consider:
- Previous gum disease
- Available bone
- Plaque control
- Smoking
- Diabetes
- Teeth grinding
Active inflammation may require gum disease treatment before implant surgery. Replacing the teeth without addressing the original problem could place the new restoration at unnecessary risk.
How Full-Arch Treatment Works
Treatment normally takes place across several stages:
- Assessment: Your teeth, gums, bone and medical history are reviewed.
- Planning: CBCT imaging helps determine suitable implant positions.
- Preparation: Failing teeth are removed, and grafting is completed if needed.
- Surgery: The implants are placed under local anaesthetic.
- Temporary bridge: Provisional teeth may be fitted when stability allows.
- Healing: The implants integrate with the jawbone.
- Final bridge: The definitive prosthesis is fitted after healing.
The surgical assessment may involve Professor Alessandro Quaranta or Dr Lizzy Hui. The surgical and prosthetic stages may be completed by different clinicians, so your team should explain who is responsible for each part.
When Fixed Teeth in a Day May Not Be Possible
Immediate loading means attaching a provisional bridge shortly after surgery. It can be convenient, but it is not suitable for everyone.
Treatment may need to be delayed because of:
- Poor bone quality
- Limited implant stability
- Extensive grafting
- Active infection
- Higher healing risks
If bone volume is limited, a dental bone graft may be considered. Allowing the implants to heal before fitting a fixed bridge can sometimes provide a safer approach.
What Affects the Cost?
The cost of full-arch treatment varies because every case requires different care. The main factors include:
- Number of implants
- One or both arches
- Tooth extractions
- Bone grafting
- Sedation
- Bridge materials
- Laboratory work
Temporary and final bridges may be priced separately. Your written treatment plan should explain what is included, possible additional procedures and expected maintenance costs.
Cleaning and Maintaining a Fixed Bridge
Although the bridge cannot decay, plaque can collect underneath it and around the implant connections. Daily cleaning remains essential.
Your routine may include:
- A soft toothbrush
- Interdental brushes
- Implant-safe floss
- A water flosser
Professional maintenance is particularly important if your teeth were lost because of periodontitis. Untreated inflammation can progress to peri-implantitis, which affects the bone supporting an implant.
Contact your dental team if you notice bleeding, swelling, discharge or movement. Smoking and poorly controlled diabetes may also affect healing and long-term implant health.

No referral is required. Where appropriate, our specialist periodontists can work with your general dentist and the clinician responsible for designing and fitting the bridge.
Frequently Asked Questions
Is All-on-4 the same as full-mouth implants?
It is one approach to replacing a complete arch of teeth. Other full-mouth treatments may use a different number or arrangement of implants based on your clinical needs.
Is full-arch implant surgery painful?
Local anaesthetic is used during surgery. Some temporary swelling, tenderness or bruising is normal afterwards and can usually be managed by following your post-treatment instructions.
Can I receive fixed teeth on the same day?
Possibly, if the implants achieve enough primary stability. Poor bone quality, extensive grafting or other clinical risks may mean the bridge needs to be fitted later.
How long does the complete treatment take?
Surgery may occur in one appointment, but healing and preparation of the final bridge generally take several months. Bone grafting may extend the overall timeframe.
Am I too old for full-arch implants?
There is no fixed upper age limit. General health, medications, gum condition, available bone and ability to maintain the restoration are usually more important than age.
Can smokers receive full-arch implants?
Smoking does not always prevent treatment, but it can affect healing and increase complications. Your specialist will discuss your individual risks and the benefits of stopping smoking.
How long can a full-arch bridge last?
Implants and bridges can provide long-term service with good care, although the bridge may eventually need repair or replacement. You can view selected dental implant results from the clinic.
How do I know if I am suitable?
A clinical examination and appropriate imaging are required. Your specialist will assess your gums, bone, medical history, smoking status, bite and ability to clean the restoration.
