What is Implant Candidacy Score?
Implant candidacy combines bone-health proxies, time since tooth loss, smoking and medical-history flags, and the number of teeth involved to estimate whether implant treatment can proceed near-term or whether pre-treatment is likely needed. This is a screening tool; final candidacy requires a CBCT scan and clinical exam.
The Formula
Near-Term Candidate = Healthy Bone + Recent Loss + Non-Smoker + Clean Medical History
Each missing piece adds time before placement: bone loss invites grafting, smoking invites cessation, certain medications invite clearance from the prescribing physician.
Worked Example
A 52-year-old missing a single molar lost about 18 months ago, no known bone loss, non-smoker, well-controlled hypertension.
- Missing teeth: one, single-tooth case is the most predictable
- Time since loss: under 2 years, bone is likely preserved
- Smoking: never, healing risk is low
- Medical history: controlled hypertension is generally cleared for implant surgery
📌 Likely candidate for a single-implant approach. A consult and CBCT scan confirm bone volume; barring surprises this is straightforward.
Why This Matters
Catch pre-work early
Most patients who are not immediate candidates become candidates after staged pre-work: grafting, smoking cessation, or improved medical control. Knowing the sequence up front sets realistic expectations.
Time changes the math
Bone in a missing-tooth site remodels over the first year. Patients who address tooth loss early avoid larger grafting later.
Common Mistakes
❌ Assuming a denture or bridge will fit the same as implants
Implants preserve bone; conventional dentures accelerate bone loss over time. The comparison is not just cost; it is what each option does to the underlying jaw over a decade.
❌ Hiding medications from the implant surgeon
Bisphosphonates, immunosuppressants, and certain blood thinners change the surgical plan. Disclosing them up front saves a cancellation on the day of surgery.
Industry Benchmarks
| Category | Good | Average | Poor |
|---|---|---|---|
| Single implant survival at 10 years | 90-95% | 85-90% | Below 80% (smokers, uncontrolled diabetics) |
| Cost per single implant with crown (US) | $3,000-4,500 | $4,000-5,500 | $5,500+ |
| Healing time before crown placement | 3-4 months | 4-6 months | 6+ months after grafting |
