All-on-4 vs. All-on-6 vs. All-on-8: Which Is Right for You?

Understanding Full-Arch Implant Solutions

For patients missing all or most teeth, “All-on-X” refers to supporting a full arch of fixed teeth with X dental implants. More implants generally mean more stability, but it’s not always better or necessary.

Head-to-Head Comparison

Factor	All-on-4	All-on-6	All-on-8
Number of Implants	4 per arch	6 per arch	8 per arch
Stability	Good for most cases	Better, especially for harder chewing	Maximum stability
Bone Requirements	Lower - often avoids grafting via angled implants	Moderate - may need more bone or minimal grafting	Highest - usually needs adequate bone volume
Surgery Complexity	Less invasive	Moderate	More complex
Cost (Turkey)	Lower (£3,000-£5,000 per arch approx.)	Mid (£4,000-£6,000 per arch approx.)	Higher (£5,000-£7,000+ per arch approx.)
Healing Time	Similar timeline	Similar timeline	Similar timeline
Best For	Good bone quality, cost-conscious, avoids grafting	Balance of stability and cost, moderate bone loss	Maximum support, bruxism, or when long-term redundancy desired
Grafting Often Needed?	Sometimes avoided with tilted implants	Less often than All-on-8, more than All-on-4 in some cases	More likely if significant bone loss

Which One Is Right For You?

Choose All-on-4 if:

• You have adequate bone in key areas (or qualify for tilted implant approach)
• You want to avoid bone grafting if possible
• Budget is a primary concern
• You have good overall oral health

Choose All-on-6 if:

• You want extra stability and peace of mind
• Moderate bone loss but still sufficient for 6 implants
• You want better force distribution
• Balance between cost and long-term security

Choose All-on-8 if:

• Significant chewing forces or bruxism (teeth grinding)
• Want maximum redundancy/stability
• Adequate bone volume exists
• Long-term durability is top priority regardless of cost
• Complex case requiring maximum support

Important Considerations

• Bone quality matters more than quantity alone: CBCT scan is essential
• Surgeon experience: Full-arch is complex - choose experienced specialist
• Not always “more is better”: All-on-4 with proper planning can be excellent
• Prosthetic design matters: The bridge design and material choice are crucial
• Maintenance is key: All options need excellent oral hygiene

Questions to Ask

• Do I need a CBCT? (Answer should be yes)
• Which option do you recommend and why? Get reasoning
• Will I need bone grafting/sinus lift? Be specific
• What’s the success rate for my bone situation?
• Which implant brand will be used? Get traceability (Lab Passport)
• What’s included in the quote? Surgery, implants, prosthesis, temporaries, aftercare?
• What’s the warranty on implants and bridge?

The Planning Process

1. Consultation & imaging: Photos, CBCT, treatment planning
2. Digital planning: Determine optimal implant positions
3. Surgery: Implants placed (often same day temporary bridge)
4. Healing: 3-6 months osseointegration
5. Final bridge: Custom zirconia/acrylic bridge fabricated
6. Follow-up: Regular maintenance

Lab-First Matters Here

For full-arch restorations, the prosthetic lab is critical. You need:

• Experienced full-arch technician
• Quality zirconia bridge design
• Proper bite registration and verification
• Material traceability
• Attention to aesthetics (not just function)

Don’t choose based on “All-on-4 vs All-on-6” alone. Choose based on proper diagnosis, surgeon expertise, and lab quality for your specific situation.
