Who Cannot Have Dental Implants? Honest Eligibility Guide

Many patients want implants but are told they "cannot have them" without clear reasoning. This guide explains specific contraindications honestly and what alternatives exist.

Many patients are told by general dentists that they "cannot have implants" without clear reasoning, leaving them confused. This guide is honest about specific contraindications, who genuinely cannot have implants, and what alternatives exist for those patients.

Absolute Contraindications (Cannot Have Implants)

A small group of patients genuinely cannot have implants safely:

Active cancer treatment with IV bisphosphonates (Zometa, Aclasta) — High MRONJ risk
Recent radiation to head/neck (within 6 months) — Bone vasculature compromised
Active untreated osteoporosis on long-term IV bisphosphonates — Same MRONJ risk
Hemophilia or severe bleeding disorders without management plan
Advanced uncontrolled diabetes (HbA1c above 10%) — Healing fails
Severe immunosuppression (active chemotherapy, AIDS uncontrolled) — Infection risk too high
Children under 18 (jaw still growing) — Wait until skeletal maturity
Active major mental health crisis affecting compliance — Cannot manage post-op care

For these patients, denture-based alternatives or no treatment may be appropriate.

Relative Contraindications (Need Special Protocols)

Many patients can have implants with modified protocols:

Diabetes (HbA1c 7-9%) — Modified protocol with extended healing, prophylactic antibiotics
Smokers — 2-week pre-surgery cessation required, reduced success rates discussed honestly
Long-term oral bisphosphonates — Drug holiday and CTX testing
Anticoagulants (warfarin, DOACs, aspirin) — Continue most through surgery
Heart conditions (cardiac risk) — Cardiologist clearance and modified protocol
Periodontal disease — Stabilisation phase before implants
Severe bone loss — Bone grafting first
Pregnancy — Defer until postpartum (3-6 months after delivery)

Common Misconceptions About Eligibility

Myth 1: "I'm too old for implants"

Reality: Age alone does not decide suitability. The named clinician must assess cardiovascular health, medications, bone, oral disease, healing capacity and the patient's goals; no first-party age or outcome claim is made here.

Myth 2: "I have no bone, so implants are impossible"

Reality: Most patients with insufficient bone can have implants after grafting. CBCT scan determines what's needed.

Myth 3: "I have allergies, so implants will fail"

Reality: Titanium allergy is extremely rare. Specific testing available for patients with concerns. Zirconia implants are an alternative for verified titanium-allergic patients.

Myth 4: "I'm a smoker, so implants won't work"

Reality: Smoking can increase implant complications and should be discussed using source-matched evidence. The named clinician must set an individual cessation and risk-management plan rather than relying on a universal time rule.

Myth 5: "My diabetes means I can't have implants"

Reality: With HbA1c below 7%, you're an excellent candidate. 7-8% requires modified protocol. Above 8%, work with your physician to bring it down before surgery.

How WeCare Screens Eligibility

Pre-treatment WhatsApp consultation:

Send X-ray, photos, and medical history
Doctor reviews everything after the required records are reviewed
Honest assessment: are you a candidate? What protocol modifications are needed?

Specific tests we may request:

Recent HbA1c (within 3 months) for diabetic patients
DEXA scan for osteoporosis patients
CTX bone marker for bisphosphonate patients
Cardiologist letter for heart conditions
Recent blood work for general health

What to Do If Told "No" by Another Clinic

If another clinic told you implants are impossible:

Get a second opinion. Many "no" responses are based on inadequate assessment or non-specialist clinics.
Send X-ray and medical history to WeCare via WhatsApp
A named, registered clinician provides any second opinion after reviewing adequate records

A responsible clinician should say when implants are not appropriate and explain reasonable alternatives. A previous opinion can be reviewed, but no eligibility reversal or outcome is promised.

Alternatives When Implants Are Truly Not Possible

For patients who genuinely cannot have implants:

Implant-retained dentures: Sometimes feasible with fewer implants and a clip-in denture

Conventional dentures: Modern dentures are significantly better than older models

Fixed bridges: Use existing teeth as support if periodontal status allows

Removable partial dentures: With clasps anchored to natural teeth

No treatment: Sometimes the right answer for terminal medical situations

Honest Conversations

A responsible screening process should:

We will tell you if you're not a candidate
The named clinician should decline implant placement when expected benefit does not justify the risk
The named clinician should document reasonable alternatives when appropriate
Payment terms should not pressure a patient before suitability, material risks and alternatives are clear

Patient safety should take priority over revenue. If you submit records, require the named clinician to explain limitations, material risks and reasonable alternatives without presenting remote advice as a final diagnosis.
