Choosing between All-on-4 and All-on-6 in Bali comes down to bone density, bite force, and which arch you're restoring. This clinical comparison breaks down indications, pricing in AUD, recovery, and longevity so Australians can pick the right full-arch solution.
TL;DR: Quick Answer
- All-on-4 uses 4 implants per arch and is generally sufficient for the upper jaw with good bone, lower bite forces, and patients without bruxism. From A$6,400 per arch with acrylic prosthesis in Bali.
- All-on-6 uses 6 implants per arch and is preferred for the lower jaw, patients with bruxism, significant bone loss in posterior regions, or those wanting zirconia bridges. From A$9,200 per arch in Bali.
- Both protocols use Straumann, Nobel Biocare, Osstem, or Dentium implants at top Bali clinics. The decision must follow a CBCT scan and prosthodontic assessment, not a price preference.
What Is All-on-4?
All-on-4 is a full-arch restoration protocol developed by Dr. Paulo Malo in the 1990s. Four implants support a fixed bridge of 10-14 teeth per arch. The two posterior implants are angled (typically 30-45 degrees) to maximize bone contact and avoid the maxillary sinus or mandibular nerve.
Best candidates for All-on-4
- Upper arch with adequate anterior bone
- Patients with normal bite force (no nighttime grinding)
- Good general health, non-smoker preferred
- Budget-conscious patients seeking the most cost-efficient full-arch solution
What Is All-on-6?
All-on-6 places six implants per arch, distributing chewing forces across more contact points. The additional two implants are typically positioned in the posterior, eliminating or reducing the cantilever extension that All-on-4 relies on.
Best candidates for All-on-6
- Lower jaw restorations (denser bone but higher bite forces)
- Patients with bruxism or heavy occlusion
- Those choosing a zirconia full-arch bridge (heavier, requires more support)
- Significant posterior bone availability that can host additional fixtures
- Patients wanting maximum long-term predictability
Clinical Comparison: 4 vs 6 Implants
| Factor | All-on-4 | All-on-6 |
|---|---|---|
| Implants per arch | 4 | 6 |
| Cantilever length | 10-15mm | 0-5mm |
| Force distribution | Concentrated on 4 points | Distributed across 6 |
| Bone graft likelihood | Lower (angled implants) | Moderate (posterior often needs grafting) |
| Surgery time | 2-3 hours per arch | 3-4 hours per arch |
| Healing/osseointegration | 3-6 months | 3-6 months |
| Recommended for bruxism | No | Yes |
| Compatible with zirconia bridge | Possible but riskier | Preferred |
| Long-term survival (5-yr) | ~94-96% | ~96-98% |
The 5-year pooled implant survival rate from Moraschini et al. (2015), Clin Oral Investig, is 94.6% across protocols using modern titanium implants (DOI:10.1007/s00784-014-1417-9). All-on-6 typically edges higher in long-term studies because force distribution reduces stress on individual fixtures.
Pricing Comparison in Bali (AUD)
Prices below assume premium implant brands (Straumann or Nobel Biocare) and include surgery, abutments, and the prosthesis. Conversion at 1 USD = 1.53 AUD.
| Procedure | Acrylic Bridge (AUD) | Zirconia Bridge (AUD) |
|---|---|---|
| All-on-4 per arch | A$6,400 - A$8,300 | A$10,700 - A$13,800 |
| All-on-6 per arch | A$9,200 - A$11,500 | A$13,800 - A$17,600 |
| All-on-4 full mouth | A$12,800 - A$16,600 | A$21,400 - A$27,600 |
| All-on-6 full mouth | A$18,400 - A$23,000 | A$27,600 - A$35,200 |
Equivalent procedures in Australia run A$25,000-A$30,000 per arch for All-on-4 acrylic and A$45,000+ for All-on-6 zirconia, meaning Bali typically saves Australians 60-70% even after flights and accommodation.

Recovery and Trip Structure
Trip 1 (Surgery): 7-10 days in Bali
- Day 1: Consult, CBCT, treatment plan finalized
- Day 2-3: Implant surgery (one or both arches)
- Day 4: Immediate-load temporary bridge fitted
- Day 5-9: Soft diet, follow-up checks
- Day 10: Final clearance, fly home
Healing window: 3-6 months at home
Osseointegration takes time. Patients eat soft foods, attend any local Australian check-ups, and return to Bali for the final prosthesis.
Trip 2 (Final Bridge): 5-7 days
- Day 1-2: Impressions or intraoral scan
- Day 3-5: Lab fabrication and try-in
- Day 6-7: Final bridge bonded, occlusion adjusted, fly home
Longevity: How Long Do Each Last?
Both protocols, when properly maintained, can last 15-25+ years. The acrylic prosthesis itself wears faster than the implants and may need replacement at 7-10 years. Zirconia bridges typically last 15+ years with proper hygiene. Annual check-ups, professional cleanings every 6 months, and a night-guard for any bruxism patients are non-negotiable.
FAQ
Can I switch from All-on-4 to All-on-6 later?
Adding implants to an existing All-on-4 is technically possible but uncommon. The new implants must integrate before the bridge is modified, and the existing prosthesis usually needs to be remade. Choose correctly the first time based on CBCT planning.
Is All-on-6 always better?
No. For an upper arch with adequate bone and normal bite force, All-on-4 has been validated by 25+ years of clinical data. Over-engineering with extra implants can mean unnecessary surgery and bone graft requirements.
Do I need a bone graft with All-on-4?
Often no, because the angled posterior implants avoid sinus and nerve structures. This is one reason All-on-4 became popular for patients with moderate bone loss.
What if I grind my teeth at night?
Bruxism makes All-on-6 the safer choice, especially for the lower jaw. A custom night-guard fabricated post-treatment is mandatory regardless of which protocol you choose.
How do Bali prices compare to Thailand or Vietnam?
Bali sits between Thailand (slightly cheaper) and Vietnam (similar to Bali) but offers strong English fluency, JCI-accredited facilities like BIMC, and direct flights from most Australian capitals. The clinical standards at top Bali clinics match or exceed regional alternatives.
Are immediate-load temporaries safe?
Yes when bone density allows primary stability above 35 Ncm at placement. Your surgeon measures torque values during surgery and only loads if criteria are met. Otherwise a removable interim is fitted while implants integrate.
What happens if one implant fails?
With All-on-6 the bridge typically remains stable on the 5 remaining implants while the failed site is regrafted and re-implanted. With All-on-4 a single failure compromises the entire bridge and usually requires full re-treatment, which is a key argument for the 6-implant protocol in high-risk patients.
Make the Right Choice for Your Mouth
The All-on-4 vs All-on-6 decision is clinical, not financial. A proper CBCT scan and prosthodontic assessment at a top Bali clinic will tell you definitively which protocol fits your anatomy, bite, and goals. Don't pick based on price alone, the cheapest option becomes the most expensive if it fails.
