| Best For | Missing few teeth, good bone | Full arch replacement, poor bone |
What Are Traditional Dental Implants?
Traditional dental implants replace teeth individually or in small groups. Each implant consists of a titanium post placed in the jawbone, an abutment, and a crown. For full arch replacement, 6-10 implants support individual crowns or a fixed bridge.
How Traditional Implants Work:
- 1. Assessment: CT scan, treatment planning, bone evaluation
- 2. Bone Grafting (if needed): 3-6 months healing before implant placement
- 3. Implant Surgery: Titanium posts placed in jawbone
- 4. Osseointegration: 3-6 months for bone to fuse with implants
- 5. Abutment Placement: Connectors attached to implants
- 6. Final Restoration: Custom crowns or bridge cemented
Traditional Implant Options for Full Arch:
- Individual Implants + Crowns: one implant per missing tooth
- Implant-Supported Bridge: several implants supporting a fixed bridge
- Implant-Supported Denture: a removable denture that clips onto implants
Traditional Implant Advantages:
- ✓ Most Natural: Each tooth individually replaced
- ✓ Long-Term Evidence: in an international review of 46 studies, 97.2%[source] of single-tooth implants survived 5 years and 95.2%[source] survived 10 years
- ✓ Long Lasting: can last many years with proper care
- ✓ Independent Teeth: If one fails, doesn't affect others
- ✓ Better Aesthetics: Individual crowns match natural teeth precisely
- ✓ Easier Cleaning: Floss between teeth normally
- ✓ Flexible Replacement: Replace missing teeth gradually over time
- ✓ Proven Long-Term: Decades of clinical evidence
Traditional Implant Disadvantages:
- ✗ Cost: more implants usually means a higher total; ask for an itemised quote
- ✗ Longer Timeline: 6-12 months from start to finish
- ✗ More Surgeries: Multiple procedures (grafting, implants, restoration)
- ✗ Bone Grafting Common: many patients need a graft first
- ✗ Temporary Solutions: Wear dentures during healing phases
- ✗ More Implants: 6-10 implants means more surgical sites
- ✗ Complex Treatment: Requires extensive planning and expertise
What Is All-on-4?
All-on-4 is a full-arch dental implant technique that uses just four strategically placed implants (two straight in front, two angled in back) to support a complete set of 10-14 replacement teeth. It's designed to maximize available bone and often avoids grafting.
How All-on-4 Works:
- 1. Planning: CT scan, digital treatment planning, prosthetic design
- 2. Surgery Day: Extract remaining teeth (if any), place 4 implants
- 3. Strategic Placement: Front implants vertical, back implants angled 30-45°
- 4. Immediate Prosthetic: Temporary fixed denture attached same day
- 5. Healing: 3-6 months osseointegration while wearing temporary
- 6. Final Prosthetic: Permanent denture fabricated and installed
All-on-4 Variations:
- All-on-4: Standard 4 implants per arch
- All-on-6: 6 implants for added stability
- Zygomatic implants: Anchored in the cheekbone for severe upper-jaw bone loss
- Branded full-arch systems: Proprietary variations on the same approach
All-on-4 Advantages:
- ✓ Fewer implants: often a lower total than many individual implants, but compare written quotes
- ✓ Same-Day Teeth: Walk out with fixed teeth on surgery day
- ✓ Fewer Implants: Only 4 implants vs 6-10 needed
- ✓ Avoids Grafting: Angled back implants use available bone
- ✓ Faster Treatment: 1-day to 3 months vs 6-12 months
- ✓ Less Invasive: Fewer surgical sites, faster healing
- ✓ Good Short-Term Survival: in an international review of 13 studies, 99%[source] of implants survived to about 3 years
- ✓ Immediate Function: Eat soft foods right away
All-on-4 Disadvantages:
- ✗ All-or-Nothing: If one implant fails, entire arch affected
- ✗ Prosthetic Replacement: Denture needs replacement every 10-15 years
- ✗ Cleaning Challenges: Requires water flosser, special tools
- ✗ Less Natural Feel: Fixed denture vs individual teeth
- ✗ Potential Bulk: Denture can feel bulky initially
- ✗ Strict Candidacy: Requires sufficient bone in specific areas
- ✗ Less Flexibility: Can't replace teeth individually later
- ✗ Shorter Track Record: Only 20 years of data vs 50+ for traditional
Cost Comparison: New Zealand 2026
These are the sourced ranges for implant treatment. All-on-4, All-on-6 and implant-supported dentures are priced per arch.
| Treatment | Price range (NZD) | Notes |
|---|---|---|
| Single dental implant (with crown) | $5,500 – $8,500 | Implant + abutment + crown. Includes consultation + 3D imaging. |
| Multiple implants (per implant, 2-4) | $4,500 – $7,500 | Volume discount per additional implant in same session. |
| All-on-4 (per arch) | $28,000 – $45,000 | Full-arch implant-supported bridge on 4 implants. Same-day teeth possible. |
| All-on-6 (per arch) | $35,000 – $55,000 | More supportive than all-on-4; for larger bone loss patients. |
| Implant-supported denture (per arch, 2-4 implants) | $14,000 – $22,000 | Removable denture clipped to implants. |
| Bone graft (sinus lift / ridge augmentation) | $1,500 – $5,000 | Often needed if bone loss present; price varies by graft size. |
Prices are per arch. Treating both jaws is two arches; no source prices both arches together, so we don't show a full-mouth total. No source prices a traditional full arch of six to ten individual implants either, because the number of implants and the bridge design vary so much.

- Auckland Dental Implants published 2026
- Lumino published rates 2026
- Dental Council scope of practice
These are national ranges. Our sources don't report city-level prices, and your own quote depends on your assessment. Always ask the clinic for an itemised written quote.
Long-term costs: a full-arch bridge may need repair or replacement over time, and individual crowns can also wear or chip. Ask each clinic what maintenance and replacement are likely to involve, and what they would cost, before you choose.

Survival & Complications: What the Evidence Shows
These figures come from international systematic reviews, not NZ data. Implant "survival" means the implant is still in place; it is not the same as a trouble-free result. Ask your dentist for their own audited survival and complication figures.
| Outcome | Traditional Implants | All-on-4 |
|---|---|---|
| Implant survival, about 3 years | See 5-year figure | 99%[source] of implants (13 studies, 4,804 implants) |
| Prosthesis survival, about 3 years | No sourced figure | 99.9%[source] of full-arch prostheses (same review) |
| Implant survival, 5 years | 97.2%[source] (single-tooth implants, 46 studies) | No sourced figure |
| Implant survival, 10 years | 95.2%[source] (single-tooth implants, 46 studies) | No sourced figure; the review authors note long-term data are lacking |
| Complications within 5 years | 3.5–8.8%[source], depending on the type of complication (single-tooth implants, same 46-study review) | No sourced figure |
Frequently Asked Questions
What is the difference between traditional implants and All-on-4?
Traditional implants replace teeth individually (1 implant per tooth) requiring 6-10 implants for full arch, while All-on-4 uses just 4 strategically angled implants to support a full arch of 10-14 teeth. Traditional implants often require bone grafting and take 6-12 months, while All-on-4 typically avoids grafting and provides same-day teeth. Ask clinics for itemised written quotes for both options.
How much do traditional implants vs All-on-4 cost in NZ?
Our sourced range for All-on-4 is $28,000 – $45,000 per arch, and All-on-6 is $35,000 – $55,000 per arch. Individual implants for two to four teeth are $4,500 – $7,500 per implant. No source prices a full arch of individually placed implants, because the number of implants and the bridge design vary so much, so ask for an itemised written quote for your case.
Which lasts longer, traditional implants or All-on-4?
Individually placed implants have the longer track record. In an international systematic review of 46 studies of implants supporting single crowns, 97.2% of implants were still in place at 5 years and 95.2% at 10 years. For All-on-4, an international systematic review of 13 studies found 99% of implants and 99.9% of full-arch prostheses survived to about 3 years, but the authors note there is little data on outcomes at 5 years or more. The denture part of an All-on-4 bridge wears and may need replacing over time. Ask your dentist for their own audited survival and complication figures.
Can you get same-day teeth with traditional implants?
While "immediate load" traditional implants exist, they're less common and require excellent bone quality. Most traditional implant protocols require 3-6 months of healing before loading with crowns. All-on-4 is specifically designed for same-day teeth, with the 4-implant configuration and fixed arch allowing immediate temporary teeth on surgery day.
Is All-on-4 as good as traditional implants?
All-on-4 is a well-established option with high implant survival over the first few years (see the table above), but traditional implants have more long-term evidence, including 10-year survival data, and a longer documented track record (50+ years vs 20 years). All-on-4 offers advantages in cost, treatment time, and avoiding grafts. For full arch replacement in patients with bone loss, All-on-4 is often the better choice. For replacing individual teeth or when bone is excellent, traditional implants may be preferred.
What happens if an All-on-4 implant fails?
If one All-on-4 implant fails early (first 6 months), it's usually replaced and the prosthetic continues functioning on 3 implants temporarily. If failure occurs years later, options include: replacing the failed implant, adding a 5th implant for support, or converting to an All-on-6 system. In traditional implants, one implant failure only affects that single tooth, not the entire arch.
