Your Guide to All-on-4 Dental Implants in Australia – and Comparing Alternative Options
All-on-4 is one approach used to replace a full arch of teeth using dental implants. It involves placing four implants in specific positions to support a fixed set of teeth.
You might also come across the term “Fixed-on-X”, which refers to a broader category of treatment. The number of implants can vary, often four or more, depending on your individual needs.
At FoX, we offer a range of full-arch solutions. And here, treatment is planned based around you. Your oral health, bone structure and goals all come together, so you can understand which option may be suitable for you.

In Summary
- All-on-4 is one method of full-arch tooth replacement using four implants, while other approaches may use a different number depending on your clinical needs.
- Treatment timeframes, costs and outcomes vary between individuals and depend on factors such as bone quality, oral health and healing response.
- All treatment options involve benefits, limitations and risks, which will be discussed during your consultation. A personalised clinical assessment is required to determine which approach may be appropriate for you.
What Are All-on-4 Dental Implants?
All-on-4 is a technique used to replace a full arch of teeth using four dental implants positioned to support a fixed prosthetic.
The placement angles are designed to work with available bone in certain areas of the jaw. In some cases, this may reduce the need for additional procedures, although this depends on individual anatomy.
How It Works:
- Four titanium implants are placed in the jawbone
- Implants are positioned based on available bone and clinical planning
- Fixed prosthetic arch attached to implants
- Temporary teeth may be fitted the same day for suitable cases*
*Treatment timelines and suitability vary. Individual assessment required.
What are the full arch options?
There are several approaches to full-arch tooth replacement. These differ in how they are planned, how many implants are used, and whether the final teeth are fixed or removable.
Rather than a single option being suitable for everyone, each approach is evaluated based on your individual needs.
Let’s compare three common options: All-on-4 vs. Fix-on-X vs. Dentures.
| Feature | All-on-4 | Fixed-on-X (FoX) | Removable Dentures |
| Number of Implants | Always 4 per arch | 4 or more (up to 6) per arch | None |
| Approach | Commonly more standard | Tailored to your anatomy | Pre-fabricated removable solution |
| Planning | Fixed technique usually, but we offer advanced imaging | Advanced 3D imaging | Basic impressions |
| Surgery Required | Yes | Yes | No |
| Stability | Fixed, doesn’t move | Fixed, doesn’t move | May shift or slip |
| Cost per Arch | $20,000–$35,000 | $20,000–$35,000 | $2,000–$5,000 |
| Treatment Time | 3-6 months | 3-6 months | Immediate |
| Customisation | Can have elements of personalisation | Planned based on individual anatomy | Limited customisation compared to implant-supported options |
| Same-Day Teeth | Maybe possible* | Maybe possible* | Immediate |
*Same-day teeth not guaranteed. Depends on individual clinical factors.
The real FoX Difference? Precision through technology
Treatment planning considers that every patient’s anatomy is different. Bone density, nerve position and bite can vary, which is why imaging and assessment play an important role.
In some cases, four implants may be appropriate. In others, additional implants may be recommended to support function and long-term stability.
- All-on-4 follows a structured approach using four implants placed in specific positions.
- Fixed-on-X is a more flexible approach where the number and position of implants are determined based on your individual anatomy using detailed imaging.
How much do these options affect the cost of dental implants in Australia?
You’ll get an itemised quote during your consultation, and we can also discuss any flexible payment options, including lending plans, superannuation release assistance and health insurance.
Approximate Investment:
- Single arch: $20,000–$35,000 (both All-on-4 and Fixed-on-X)
- Full mouth (both arches): $40,000–$70,000
What Affects Your Cost:
- Teeth requiring extraction
- Bone grafting or preparatory work needed
- Prosthetic materials selected
- Sedation type (local or general anesthesia)
- Location
Who is a good candidate for All-on-4?
Suitability for full-arch implants depends on your health, which is carefully assessed during your consultation.
You may be suitable if:
- You have significant tooth loss or failing teeth requiring extraction
- You have adequate bone density in specific jaw areas
- You’re in good overall health with realistic expectations
- You’re a non-smoker or willing to quit
Conditions requiring further assessment:
Diabetes, autoimmune conditions, osteoporosis, bone loss, smoking status and medications affecting healing all require evaluation during your consultation.
What’s the recovery timeline like for All-on-4?
Recovery depends on a range of health considerations, plus how well you follow your aftercare instructions.
Here’s what many patients can expect following All-on-4 dental implants:
- First Week: Discomfort and swelling are common. Some patients experience bruising or difficulty speaking.
- 2-4 Weeks: Initial healing progresses. Modified diet continues as tissue adapts.
- 3-6 Months: Osseointegration occurs as implants bond with bone. Regular monitoring appointments required.
- Complications: Some patients experience prolonged discomfort, infection or implant failure requiring additional treatment.
What can you eat after All-on-4?
- First Few Days: Liquids and very soft foods only, things like protein shakes, smoothies and yogurt are safe foods. Avoid hot foods/drinks initially.
- First 2-4 Weeks: Soft foods requiring minimal chewing like scrambled eggs, mashed vegetables, soft fish. Avoid hard, crunchy or sticky foods.
- After Full Healing (3-6 Months): Gradual return to normal diet. Most foods can be enjoyed. We’ll let you know when it’s safe to start the transition.
How long do All-on-4 implants last?
Implants may last many years with proper care. The teeth attached to them will naturally experience wear over time and may eventually need refreshing, much like any restoration.
Every person’s experience is different, which is why we can’t promise exact timelines. However, longevity can vary considerably based on:
- Individual healing response and bone quality
- Daily oral hygiene maintenance
- Professional care compliance (check-ups every 6 months)
- Smoking status and overall health
- Bite forces and grinding habits
What are the risks and success rates of All-on-4?
All surgical procedures carry risks, including infection, nerve damage, sinus complications, implant failure, chronic pain and adverse reactions to anesthesia. Some patients experience complications requiring additional intervention.
Your outcome really depends on multiple factors working together and how your body naturally heals.
Many patients maintain their implants successfully for years, though your experience will always be individual to you.

FAQs:
What’s the main difference between All-on-4 and Fixed-on-X?
All-on-4 uses exactly four implants, while Fixed-on-X customises the number and positioning based on your individual anatomy. Either way, we’ll use advanced 3D imaging and technology to ensure optimal placement for your specific bone structure.
How long does the All-on-4 procedure take?
The surgical procedure typically takes 2-3 hours per arch. Your complete treatment timeline, from consultation to final restoration, spans 3-6 months for proper healing and osseointegration.
Will I have teeth immediately after my All-on-4 surgery?
For many suitable cases, temporary teeth can be attached the same day. This isn’t guaranteed and depends on your individual clinical situation and healing requirements.
How do I maintain my implants?
Brush and floss daily around implants, attend check-ups every 6 months, avoid smoking and follow all aftercare instructions. Proper maintenance significantly impacts long-term success.
Can I get implants if I have bone loss?
Possibly. The Fixed-on-X technique is designed to work with available bone through strategic positioning. However, severe bone loss may still require grafting.
The only way to determine suitability is during a clinical assessment. You’ll also get more information on risks, benefits and pricing.
