Differences Between All-On-8 Dental Implants vs All-On-4 & All-On-6
When it comes to full-mouth dental restoration, modern dental implants offer revolutionary solutions for people with missing teeth. All-On-4, All-On-6, and All-On-8 dental implants are popular treatments that restore a patient’s smile by supporting an entire arch of teeth on a set number of implants. But what are the key differences between these three options, and how do you choose the right one for your needs?
Understanding All-On-4, All-On-6, and All-On-8
All-On-4 Dental Implants
- Definition: The All-On-4 system uses 4 strategically placed implants to support a full arch of prosthetic teeth.
- Implant Placement: Two implants are placed vertically in the front jawbone, and two are tilted at an angle in the back for optimal support.
- Ideal For: Patients with limited bone density, offering a minimally invasive full-arch solution.
All-On-6 Dental Implants
- Definition: The All-On-6 system uses 6 implants instead of 4, providing additional stability and distribution of chewing forces.
- Implant Placement: 6 implants are evenly spaced across the jawbone, offering better load distribution than the All-On-4 system.
- Ideal For: Patients with moderate to good bone density who need a more robust foundation.
All-On-8 Dental Implants
- Definition: The All-On-8 system uses 8 implants to secure the prosthetic teeth firmly in place.
- Implant Placement: 8 implants are placed across the jawbone, maximizing support and ensuring greater longevity.
- Ideal For: Patients with excellent bone density who are looking for maximum stability and a permanent solution.

Pros and Cons of Each Treatment
All-On-4 Pros
✅ Cost-effective compared to other systems.
✅ Suitable for patients with bone loss.
✅ Faster recovery due to fewer implants.
All-On-4 Cons
❌ Less stable for patients with strong bite forces.
❌ May require replacement sooner compared to All-On-6 or All-On-8.
❌ Limited load distribution.
All-On-6 Pros
✅ Better load distribution compared to All-On-4.
✅ Greater stability for long-term use.
✅ Suitable for patients with moderate bone density.
All-On-6 Cons
❌ More expensive than All-On-4.
❌ Requires sufficient jawbone for placement.
All-On-8 Pros
✅ Maximum stability for a long-lasting solution.
✅ Excellent load distribution, ideal for strong bite forces.
✅ Provides the most natural feel and function.
All-On-8 Cons
❌ Most expensive of the three options.
❌ Requires excellent bone density.
❌ Longer procedure time and recovery.
Which Option is Right for You?
Choosing All-On-4
- Best for: Patients with significant bone loss who want a cost-effective solution.
- Consideration: It’s ideal for people with low bone density or those who want a minimally invasive procedure.
Choosing All-On-6
- Best for: Patients with moderate jawbone density who need a strong, balanced solution.
- Consideration: It offers greater stability and durability compared to All-On-4.
Choosing All-On-8
- Best for: Patients with excellent bone density who need a permanent, highly stable solution.
- Consideration: If cost is not a barrier, All-On-8 provides the best long-term results with optimal support and comfort.
Conclusion
Choosing between All-On-4, All-On-6, and All-On-8 dental implants depends on your individual needs, bone density, and budget.
- All-On-4 offers a cost-effective, minimally invasive option for those with limited bone support.
- All-On-6 provides additional stability and is ideal for moderate bone density.
- All-On-8 ensures maximum support, load distribution, and longevity for patients with excellent bone structure.
Consulting with a dental implant specialist will help determine the best solution for your oral health, lifestyle, and budget.
Frequently Asked Questions (FAQs)
What is the main difference between All-On-4, All-On-6, and All-On-8 dental implants?
The primary difference lies in the number of implants used to support a full arch of prosthetic teeth. All-On-4 uses 4 implants, All-On-6 uses 6 implants, and All-On-8 uses 8 implants. The higher the number of implants, the better the stability and load distribution.
Which option is the most affordable?
All-On-4 is the most affordable option because it uses fewer implants and typically requires a shorter procedure time. However, the choice depends on individual needs and bone density.
How long do All-On-4, All-On-6, and All-On-8 dental implants last?
With proper care and maintenance, all three options can last 15–20 years or more. All-On-6 and All-On-8 may last longer due to their superior stability and load distribution.
Do I need sufficient bone density for All-On-8 dental implants?
Yes, All-On-8 implants require excellent bone density to support 8 implants. If you have significant bone loss, your dentist may recommend bone grafting or All-On-4 implants instead.
Is the recovery time different for each option?
Yes, the recovery time may vary:
- All-On-4: Faster recovery due to fewer implants.
- All-On-6: Moderate recovery time.
- All-On-8: Slightly longer recovery due to additional implants.
However, recovery largely depends on the patient’s health and adherence to post-procedure care.
Can I eat normally after getting dental implants?
Yes, dental implants restore full chewing functionality. After the initial healing period, you can enjoy most foods, including crunchy and chewy items.
Are All-On-4 implants secure enough for daily use?
Yes, All-On-4 implants are secure and durable for everyday use, even for patients with limited bone density. However, if you have stronger bite forces or want added stability, All-On-6 or All-On-8 may be better options.
Will the dental implants look and feel natural?
Absolutely! All-On-4, All-On-6, and All-On-8 implants are designed to provide a natural appearance and feel. The prosthetic teeth are customized to match your facial structure and smile.
What happens if I don’t have enough bone for implants?
If you don’t have enough bone, your dentist might suggest:
- Bone grafting to rebuild jawbone density.
- Choosing All-On-4 implants, which are better suited for limited bone volume.
Which dental implant option is best for long-term durability?
All-On-8 offers the highest level of stability and durability due to the increased number of implants. However, All-On-6 is also a strong and long-lasting solution for most patients.
