Key takeaways
Adequate bone volume is the primary requirement - confirmed via CBCT scan by a qualified surgeon
Uncontrolled diabetes, bisphosphonate use, and active jaw cancer are typically absolute contraindications
Smoking significantly impacts healing and may disqualify or delay treatment
All-on-6 may offer better stress distribution than All-on-4, with 94-98% long-term implant survival rates in appropriate candidates
A thorough pre-treatment evaluation including medical history review is essential before proceeding
Understanding All-on-6 Dental Implants
All-on-6 is a full-arch restoration technique that uses six strategically placed dental implants to support a permanent prosthetic bridge. This approach serves as an alternative to traditional dentures and the more limited All-on-4 concept [S3].
For patients with complete or near-complete tooth loss in one or both jaws, All-on-6 may provide a fixed, permanent solution that functions like natural teeth. The six implants are positioned to maximize bone contact and provide stable support for the prosthetic arch.
What Makes Someone a Good Candidate
According to the American Academy of Periodontology, ideal candidates must have adequate bone in the jaw to support the implant, healthy gum tissues free of periodontal disease, and good general and oral health [S1]. These requirements form the foundation of any candidacy assessment.
The American Dental Association confirms that overall health is an important factor in determining implant candidacy, with chronic illnesses potentially interfering with healing after surgery [S2]. This means your general health status plays a significant role in determining whether treatment may proceed.
Core eligibility requirements include:
Adequate bone volume and density in the jaw to support six implants
Healthy gum tissues free of active periodontal disease
Good general health with ability to undergo oral surgery
Commitment to excellent oral hygiene following treatment
Non-smoker or willingness to quit before and during treatment process
Bone requirements vary by individual and must be determined through cone beam computed tomography (CBCT) imaging. This 3D scan allows the surgeon to assess bone quality, quantity, and density precisely.
Age Considerations
There is no strict upper age limit for All-on-6 treatment. What matters is overall health and bone quality rather than chronological age. However, younger patients should have completed jaw growth, which typically occurs around ages 16-18 for females and 18-21 for males. A qualified dental surgeon can assess whether jaw development is sufficient.
Medical and Health Requirements
Your medical history plays a crucial role in determining candidacy. Some conditions may completely preclude treatment, while others require careful evaluation and potential management before proceeding.
Absolute Contraindications
The following conditions typically disqualify patients from receiving All-on-6 implants:
Uncontrolled medical conditions such as diabetes or leukemia
Recent history of bisphosphonate use, particularly intravenous bisphosphonates
Active cancer in the jaw area
Recent radiation therapy to the jaw
Severe uncontrolled gum disease
These conditions affect healing capacity or create unacceptable risk levels that make the surgical procedure inadvisable.
Health Conditions That May Affect Treatment
Several conditions require special evaluation before determining candidacy:
Diabetes: Uncontrolled diabetes may affect healing after surgery [S2]. Patients with well-controlled diabetes may still be candidates, but blood sugar management must be discussed with both your dentist and physician.
Smoking: Smoking can significantly slow healing [S2]. Many providers require patients to quit smoking before and during the treatment process. This is a modifiable factor that can improve outcomes substantially.
Cardiovascular disease and bleeding disorders: These conditions require careful evaluation and may necessitate physician clearance before treatment can proceed.
Osteoporosis: Particularly important if you're taking oral bisphosphonates. This medication can affect jawbone healing and requires thorough assessment.
Bruxism: Heavy teeth grinding may place excessive force on implants, potentially affecting long-term success. Your provider may recommend a night guard.
Bisphosphonate Considerations
Intravenous bisphosphonates (commonly used for certain cancer treatments) carry significant risk of jaw necrosis following dental surgery. Always disclose any bisphosphonate use to your dental provider, including the type, duration, and reason for treatment.
Pre-Treatment Evaluation: What to Expect
A comprehensive pre-treatment evaluation is essential before determining candidacy. This process typically includes:
Medical history review: Your provider will discuss existing medical conditions, medications, and overall health status. Be prepared to disclose all medications, including supplements and over-the-counter drugs.
Dental examination: A thorough oral examination to assess gum health, remaining teeth, and overall oral hygiene.
Imaging studies: CBCT scans provide 3D images of your jawbone, allowing precise assessment of bone quantity and quality. This is non-negotiable for treatment planning.
Discussion of expectations: Your provider should understand your goals and ensure they align with what treatment can realistically achieve.
Questions to Ask Your Provider
When evaluating a potential provider, consider asking:
What is your experience with All-on-6 procedures specifically?
What implant brands do you use, and why?
What happens if I don't have enough bone for implants?
How do you handle complications if they arise?
What is your success rate with this procedure?
Will I need bone grafting, and if so, what type?
All-on-6 vs All-on-4: Understanding Your Options
Both All-on-6 and All-on-4 are full-arch solutions available through dental treatments options, but they differ significantly:
All-on-6 uses six implants compared to four in the All-on-4 technique. According to clinical research, All-on-6 may show better stress distribution across the prosthetic framework, potentially reducing risk of prosthetic screw loosening and implant overload [S3]. This makes All-on-6 particularly suitable for atrophied (shrunken) maxillae.
The additional two implants in All-on-6 provide greater support and redundancy. However, the choice between these options depends on your specific bone structure, which can only be determined through proper imaging and specialist evaluation.

Recovery and Success Factors
Long-term studies show dental implant survival rates of 94-98% over 10-15 years in appropriate candidates [S4]. Success depends on multiple factors including proper placement, patient health, and diligent aftercare.
Recovery timeline varies but generally involves:
Initial healing: 2-4 weeks for soft tissue
Osseointegration: 3-6 months for bone to fuse with implants
Final prosthesis: Typically placed 4-6 months after implant surgery
For patients considering treatment in Istanbul, plan for adequate recovery time before travel. Most providers recommend remaining in the area for at least 3-7 days after surgery for initial monitoring.
Success rates are population averages and individual outcomes may vary. Factors such as smoking, diabetes control, oral hygiene, and following post-operative instructions all influence results. A qualified dental surgeon can assess your specific situation.
