Suitability for All-on-4® dental implants cannot be determined by reading an article. It cannot be determined by a questionnaire alone, or by what a previous dentist said about your bone volume in the context of conventional implant placement. It is determined by a clinical assessment: specifically, a cone beam CT scan evaluating your bone volume, density, and anatomy, combined with a thorough medical history review and a detailed conversation with a qualified dental surgeon who specialises in full arch implantology.
What this article can do is address the most common self-disqualifications we hear, so you arrive at that assessment with accurate expectations rather than unfounded conclusions.
Age alone is not a clinical contraindication for All-on-4® dental implants. There is no standard upper age limit. What determines whether a patient can safely undergo implant treatment is their overall health status, not their chronological age.
Patients in their 70s and 80s have All-on-4 treatment successfully performed when their general health supports it.
The relevant clinical questions are not how old you are, but whether your cardiovascular health, your medication profile, your healing capacity, and your bone density support a surgical procedure.
Your surgeon assesses all of these during your consultation. Age is considered as part of the full clinical picture, not as a barrier in isolation.
Controlled diabetes, particularly well-managed Type 2 diabetes, does not automatically exclude a patient from implant treatment. The clinical literature on implant outcomes in patients with controlled diabetes is broadly supportive of treatment in appropriately selected and prepared patients, provided blood glucose levels are well managed during the treatment period.
Poorly controlled or unstable diabetes represents a different clinical picture and requires careful discussion with your surgeon before proceeding. Your surgeon will review your most recent HbA1c levels as part of your pre-treatment assessment. If additional preparation or coordination with your GP or endocrinologist is required before treatment can proceed safely, your team will outline that clearly.
Individual guidance from your care team takes precedence over general information. Follow their specific instructions for your case.
Concern | Automatic Exclusion? | Clinical Reality | What Is Assessed |
Age (60, 70, 80+) | No | Health status determines candidacy, not age | General health, medications, healing capacity |
Controlled Type 2 diabetes | No | Evidence supports treatment in well-managed patients | HbA1c levels, diabetes stability, GP coordination |
Smoking history | No | Elevated risk, not automatic exclusion | Current smoking status, level, patient discussion |
Significant bone loss | No (often) | Tilted implant placement often addresses this | CBCT bone volume and density assessment |
Treated gum disease (stable) | No | Stable periodontitis is not necessarily a contraindication | Current gum health, disease activity, stability period |
Severe bone loss (atrophic jaw) | Possibly | Zygomatic implants may be an alternative | Specialist hypercomplex case assessment |
Active, untreated gum disease is a contraindication for implant placement. It must be stabilised and treated before surgery.
Treated, stable gum disease, where the disease has been professionally managed and is no longer active, is a different clinical situation. Many patients with a history of periodontal disease proceed with successful All-on-4® treatment concept.
Your surgeon will assess your current gum health, the stability of any prior disease, and your ongoing hygiene capacity as part of your clinical evaluation.
Being told you do not have enough bone for implants is one of the most common reasons patients assume All-on-4® dental implants are not available to them. In many cases, this assessment was made in the context of conventional, axially placed individual implants, which require sufficient posterior bone for standard placement.
The Malo Protocol’s posterior angulation technique is specifically designed to engage the denser anterior bone region, which allows implants to be placed without grafting in many patients who would require grafting for conventional axial implants. A patient told they need significant bone grafting for conventional implants may still be a candidate for All-on-4® without grafting. Only a CBCT scan can confirm this for your specific anatomy.
For cases where bone volume is severely compromised even for angulated All-on-4® dental implant placement, zygomatic implants, which anchor into the dense cheekbone rather than the jaw, may be an option.
If you’re struggling with loose dentures, living with painful or missing teeth, All-on-4® dental implants can offer you a long-term, fixed alternative to dentures.
