Many patients who come to my clinic for All-on-4 implants arrive with the same question: “I have a health condition; can I still get dental implants?”
Can You Get All-on-4 Implants If You Have a Health Condition?

For most patients, the answer is yes. Having a medical condition does not automatically exclude you from All-on-Four implants. What matters is how well your condition is managed.

Receiving All-on-4 Implants with Diabetes
Diabetes is one of the most common conditions I see in All-on-4 candidates, and it's fully manageable in most cases. The key factor for All-on-4 is how well your blood sugar is controlled.
Why it matters:
- Poorly controlled diabetes slows wound healing.
- It increases post-surgical infection risk.
- It can interfere with osseointegration, which is the process by which implants fuse with the jawbone.
Who is likely to be suitable:
- Patients with well-managed type 2 diabetes and a stable HbA1c below 8% typically achieve results comparable to non-diabetic patients.
- Type 1 diabetes is not an automatic contraindication, but requires more detailed pre-surgical planning.
We work closely with your GP or diabetologist before and after surgery to ensure glucose levels are optimised throughout healing.
Osteoporosis and All-on-4 Implants
Because All-on-4 relies on bone for implant stability, patients understandably worry about reduced bone density. What most don’t know is that All-on-4 was actually designed for patients with low bone volume. The angled placement of these implants avoids the need for bone grafting when you have some jawbone loss.

- Oral bisphosphonates (low dose): Carries a small risk. We review the specific drug, dose, and duration before proceeding.
- Intravenous bisphosphonates (high dose): Carry a higher risk of medication-related osteonecrosis of the jaw (MRONJ), a rare but serious condition.
Patients on bisphosphonates may need a “drug holiday”, where you pause all medication, before undergoing All-on-4 treatment.
Can You Get All-on-4 Implants with Heart Disease or High Blood Pressure?
In short, yes, but only under certain conditions.
Patients with well-controlled high blood pressure, a past heart attack, or coronary artery disease can usually have All-on-4 surgery, as long as their health is stable and their cardiologist approves.
Blood thinners such as warfarin, apixaban, or clopidogrel also require specific attention. Stopping these medications without guidance is dangerous, so we liaise directly with your prescribing doctor to establish a safe protocol around the surgical date.
Possibility of Implants with Autoimmune Conditions and Immunosuppression
If you have conditions that suppress your immune system, dentists typically don’t recommend implant surgery. However, this is not a firm no as there are many types of autoimmune conditions.
You may be able to receive All-on-4 dental implants with conditions such as rheumatoid arthritis, lupus, or Crohn's disease managed with immunosuppressant medication. Dentists usually do a comprehensive medical review with other medical professionals before recommending the surgery.
Blood thinners such as warfarin, apixaban, or clopidogrel also require specific attention. Stopping these medications without guidance is dangerous, so we liaise directly with your prescribing doctor to establish a safe protocol around the surgical date.
For some, such as those with HIV/AIDS and advanced type II diabetes, we don’t recommend implants. For diabetes, as mentioned above, blood sugar should be stable before receiving implants.
Important considerations for patients with immunosuppression:
- Patients on stable, long-term immunosuppression can go on to have successful implant treatment with medical review.
- The specific drug, dose, and how well the condition is currently controlled all influence surgical risk
- A multidisciplinary approach, involving your rheumatologist or gastroenterologist, is standard in complex cases.
How We Assess Medical Suitability for All-on-4 Implants at Complete Smiles
At Complete Smiles, we review the following before recommending treatment:
- Current medications and dosages
- Recent blood results
- GP and specialist correspondence
- Condition stability and control
Complex cases are discussed directly with your wider care team. For those with complex issues, this may extend the initial consultation period. We work as fast as possible, but we cannot take shortcuts with medical reviews to assess surgical risk.
If you are unsure whether your health history makes you a suitable candidate, bring your medication list to a consultation. The first All-on-4 consultation with us is bone grafting.
The bottom line is that smile restoration with dental implants is not out of reach even for those with preexisting conditions, as long as there’s a thorough review of your condition. To learn more, call us or book an appointment online.
