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: 10-14 implants, most natural - $50,000-$70,000+
- Implant-Supported Bridge: 6-8 implants, fixed bridge - $35,000-$50,000
- Hybrid Approach: 6 implants, removable/fixed prosthetic - $30,000-$45,000
Traditional Implant Advantages:
- ✓ Most Natural: Each tooth individually replaced
- ✓ Highest Success Rate: 95-98% per implant (long-term data)
- ✓ Longest Lasting: 20-30+ 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:
- ✗ Higher Cost: $30,000-$60,000+ per arch
- ✗ Longer Timeline: 6-12 months from start to finish
- ✗ More Surgeries: Multiple procedures (grafting, implants, restoration)
- ✗ Bone Grafting Common: 60-70% of patients need grafts
- ✗ 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 - $25,000-$35,000 per arch
- All-on-6: 6 implants for added stability - $30,000-$40,000 per arch
- All-on-X (Zygoma): Includes cheekbone implants for severe bone loss - $35,000-$50,000
- Pro Arch: Proprietary All-on-4 system - $28,000-$38,000
All-on-4 Advantages:
- ✓ Lower Cost: $25,000-$35,000 vs $30,000-$60,000 traditional
- ✓ 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
- ✓ High Success Rate: 94-97% when done by experienced dentist
- ✓ 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

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. Traditional costs $30,000-$45,000 per arch vs $25,000-$35,000 for All-on-4 in New Zealand.
How much do traditional implants vs All-on-4 cost in NZ?
In New Zealand (2026), traditional dental implants cost $5,000-$7,000 per tooth, totaling $30,000-$60,000+ for full arch replacement (6-10 implants plus bridge). All-on-4 implants cost $25,000-$35,000 per arch for complete treatment including 4 implants and fixed denture. All-on-4 is typically $5,000-$15,000 less expensive per arch than traditional implants.
Which lasts longer, traditional implants or All-on-4?
Traditional implants typically last longer than All-on-4. Individual traditional implants last 20-30+ years with 95-98% success rate, while All-on-4 prosthetics last 10-20 years with the implants themselves lasting 15-25 years. However, both offer long-term solutions. All-on-4 prosthetics may need replacement sooner due to wear on the denture portion, while individual implants rarely need replacement if successful.
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 an excellent solution with 94-97% success rates, but traditional implants have slightly higher long-term success (95-98%) and 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.
