Key takeaways
All-on-6 uses six vertically placed implants to support a full-arch prosthesis, offering favorable stress distribution on cortical bone compared to All-on-4.
Success depends on individual factors including bone quality, oral hygiene, systemic health, and smoking status—these vary significantly between patients.
Not all patients have sufficient bone volume for six implants without grafting procedures, which can affect cost and treatment timeline.
When seeking treatment in Istanbul, verify provider experience, facility accreditation, and clear aftercare protocols before committing.
Understanding All-on-6 Dental Implants
What Is the All-on-6 Protocol?
The All-on-6 protocol is a full-mouth rehabilitation approach that uses six dental implants to support a complete arch of prosthetic teeth. Unlike traditional implant methods that require an implant for each missing tooth, All-on-6 provides a fixed, implant-supported prosthesis using just six strategically placed implants per arch S1.
The six implants are placed vertically in the jawbone, typically avoiding the need for tilted or angled implants that other protocols may require. This vertical placement can provide more straightforward surgical planning and may benefit patients with adequate bone volume in the anterior jaw region S1.
For patients exploring various dental treatment options for full-mouth restoration, All-on-6 represents one approach among several available protocols. Our dental resource hub provides additional context for comparing different treatment approaches.
The prosthetic arch is then attached to the implants, creating a fixed set of teeth that does not need to be removed for cleaning like removable dentures. This can provide improved stability and function compared to traditional removable options.
Who Makes a Good Candidate?
Candidacy for All-on-6 treatment depends on several factors that vary significantly between individuals. Ideal candidates typically have:
Adequate bone volume: Sufficient jawbone to support six implants without requiring extensive grafting procedures S2
Good oral hygiene: Commitment to maintaining implant prostheses long-term
Generally healthy systemic condition: Certain medical conditions may affect candidacy or require special consideration S2
Patients with uncontrolled diabetes, severe cardiovascular disease, or immunocompromised conditions may face higher risks and require additional evaluation S2. Smoking also significantly impacts implant success rates and should be disclosed to providers S2.
Comprehensive imaging, typically including CBCT scans, is essential for determining individual candidacy and planning precise implant placement. No definitive candidacy determination can be made without this detailed examination.
Key Point
Bone quality and volume are critical factors. Patients with insufficient bone may require bone grafting procedures, which can increase overall treatment cost and extend the timeline.
Comparing All-on-6 to Other Options
All-on-6 vs All-on-4: Key Differences
Both All-on-4 and All-on-6 are established protocols for full-mouth rehabilitation, but they differ in several important ways:
Feature
All-on-4
All-on-6
Number of implants
4 implants per arch
6 implants per arch
Implant placement
2 tilted, 2 vertical
All vertical
Bone requirements
Can often avoid grafting
More bone typically needed
Stress distribution
Favorable on trabecular bone
More favorable on cortical bone
Complexity
Generally simpler
More complex surgical phase
Research using three-dimensional finite element analysis has shown that All-on-6 demonstrates more favorable stress distribution on cortical bone and implants compared to All-on-4, with lower maximum principal stress values under various loading conditions S1. However, All-on-4 showed slightly better stress distribution on trabecular bone under vertical and horizontal loading S1.
Both concepts are viable options for full-mouth rehabilitation in edentulous patients S1. The choice between them depends on individual anatomy, bone quality, and clinical assessment.
All-on-6 vs Removable Dentures
For patients who have considered removable dentures as an alternative, All-on-6 offers several potential advantages:
Improved stability: Fixed implants do not slip or shift during eating or speaking
Bone preservation: Implants help prevent bone resorption that typically occurs with removable dentures S1
No adhesive requirements: Eliminates the need for denture adhesives
Enhanced comfort: No pressure on gums or palate
However, removable dentures remain a less invasive option with lower upfront cost. They may be more suitable for patients who cannot undergo surgery or have significant medical constraints S2.
Considerations
The decision between fixed implants and removable dentures involves trade-offs between cost, invasiveness, long-term maintenance, and personal preferences. Discuss these factors thoroughly with a qualified provider.
What the Research Shows
Biomechanical Findings
A peer-reviewed biomechanical study using three-dimensional finite element analysis compared stress distribution between All-on-4 and All-on-6 treatment concepts S1. The key findings include:
All-on-6 showed smaller maximum principal stress values on cortical bone compared to All-on-4, indicating more favorable stress distribution in this critical bone region S1
All-on-6 demonstrated lower stress on implants themselves, which may contribute to long-term implant survival S1
All-on-4 showed advantages for trabecular bone stress distribution under both vertical and horizontal loading conditions S1
These findings suggest that All-on-6 may provide more favorable overall biomechanical behavior for patients with adequate cortical bone density S1.
Success Rates and Complications
Long-term clinical survival data specifically comparing All-on-6 to All-on-4 remains limited. While biomechanical studies show favorable stress distribution, outcomes can vary significantly based on:
Individual patient factors: Bone quality, oral hygiene, systemic health conditions
Surgical precision: Proper implant placement and prosthetic connection
Maintenance: Regular follow-up care and prosthesis maintenance
As with any full-arch prosthesis, mechanical complications can occur, including screw loosening, prosthesis fracture, and wear requiring maintenance S1. These issues are not unique to All-on-6 and may occur with various implant-supported prosthetic options.
Risks, Limitations, and Contraindications
Medical Contraindications
Certain medical conditions may affect candidacy for All-on-6 treatment or require special consideration:
Uncontrolled diabetes: May impair healing and increase infection risk S2
Severe cardiovascular disease: Requires careful evaluation before surgery
Immunocompromised conditions: May affect wound healing and infection resistance
Bleeding disorders: Surgical procedures require adequate clotting function
Certain medications: Bisphosphonates and other drugs may affect implant success S2
A comprehensive medical evaluation by qualified clinicians is essential before proceeding with treatment S2.
Surgical and Prosthetic Risks
All surgical procedures carry inherent risks. For All-on-6 specifically, patients should be aware of:
Bone grafting risks: If grafting is required, additional complications may apply
Results vary based on individual anatomy, oral hygiene practices, and systemic health factors S2. Patients should have realistic expectations and understand that ongoing maintenance is required.
Red Flags to Avoid
Be cautious of providers who guarantee outcomes, claim "zero risk," or pressure you to decide immediately without comprehensive evaluation. Legitimate providers will emphasize the need for individual assessment and discuss potential complications openly.
Is All-on-6 Right for You?
Questions to Ask Your Provider
When evaluating All-on-6 treatment, consider asking these questions:
How many All-on-6 procedures have you performed, and can you provide before/after cases?
What is your success rate with this specific protocol?
What imaging do you recommend for treatment planning, and why?
Am I likely to need bone grafting? If so, what type and why?
What are the potential complications specific to my case?
What is your protocol if an implant fails?
How do you handle aftercare once I return home?
What is included in the quoted price, and what additional costs might arise?
Evaluation and Treatment Planning
A comprehensive evaluation should include:
