Twenty a Day, and He Wanted Three Implants

Quick answer: Smoking roughly doubles the rate of implant failure and substantially raises the rate of later bone loss around implants. It is not an absolute barrier, and it is the single largest thing a patient can change — which makes it a conversation worth having properly rather than a box to tick.

The call

He asked, in the first minute, whether we were going to lecture him. He had been to a practice that had, and he had not gone back.

Amnon, 54, who works at the industrial zone in Har Tuv, had lost three lower back teeth over several years and wanted implants. He had smoked twenty a day for thirty-two years.

The lecture is counterproductive and the information is not. Those are different things.

What we found

Three edentulous spaces in the lower left, healed, with adequate bone height and width on the scan. No periodontitis currently, though there was evidence of past bone loss. Reasonable hygiene.

Clinically, a straightforward case. The complication was entirely in the risk profile.

What smoking actually does to an implant site, and it is worth being specific rather than gesturing at "healing":

• Nicotine constricts blood vessels, reducing blood flow to the surgical site exactly when it is needed most.
• Carbon monoxide reduces the oxygen-carrying capacity of the blood that does arrive.
• Neutrophil and macrophage function is impaired, so bacterial contamination is less well controlled.
• Osteoblast activity is suppressed — the cells that lay down bone against the implant surface work less well.
• Heat and smoke at the site during the healing phase.

The numbers, stated honestly. Reported implant failure rates in smokers run at roughly double those in non-smokers across a large body of literature. Peri-implantitis — the late bone loss that costs implants years later — is also substantially more common. The effect appears dose-related, and heavy smokers do worse than light ones.

Roughly double is not a prohibition. Implant success rates are high enough that doubling the failure rate still leaves most implants succeeding. Presenting it as futile is as inaccurate as presenting it as irrelevant.

What that meant for him specifically: three implants, in the lower jaw, where bone quality is better and smoking's effect is somewhat less pronounced than in the upper. Better odds than an upper case, worse than a non-smoker.

What we did

Gave him the numbers, in writing, and did not moralise. He was told the failure rate roughly doubles, that the late bone loss risk is higher, that the effect is dose-related, and that the practice's policy on replacing a failed implant would differ for a smoker — a failure attributable to a modifiable risk factor he had chosen to keep is not something we replace free of charge, and he needed to know that before starting rather than after.

Asked for eight weeks of cessation before surgery and eight weeks after, not permanent quitting. That framing matters. "Stop smoking forever" is a demand most people fail; "stop for four months around the surgery" is a defined task with an endpoint, and a meaningful proportion of people who manage it do not restart.

The evidence for a perioperative quit is not as strong as one would like, and the biological rationale is sound and the ask is proportionate.

Referred him to his kupah's cessation programme and discussed nicotine replacement, which does not carry the carbon monoxide load and is a reasonable bridge.

Offered the alternative honestly. A three-unit bridge, which does not depend on bone healing and is far less affected by smoking. For a smoker unwilling or unable to stop, a bridge is frequently the better recommendation, and saying so is not a failure of ambition.

He chose the implants and the quit.

He managed nine weeks before and about six after, then went back to roughly ten a day.

Surgery staged, one implant at a time rather than three together, so that a failure would not compromise the whole case.

Extended healing periods — four months rather than three.

Three-monthly maintenance, permanently, which for a smoker with implants is not optional.

The outcome

All three integrated and were restored over about fourteen months.

At four years, two are entirely stable. The third has 2mm of bone loss with bleeding on probing — early peri-implantitis, being managed with intensified maintenance and closely watched.

That is a reasonable outcome and it is a fair illustration of the risk being real rather than theoretical. He knows the third one may not last, and he knew that before it was placed.

He has cut down to about ten a day and has not stopped.

What to do if this happens to you

1. Ask for the numbers, not adjectives. Roughly double the failure rate is the honest figure.
2. Ask what the practice's policy is on replacing a failure in a smoker. Ask before, not after.
3. Aim for a defined quit window — eight weeks either side — rather than an open-ended commitment.
4. Ask about a bridge as an alternative. It is far less smoking-sensitive.
5. Expect staged placement and longer healing. Both are reasonable adjustments.
6. Commit to three-monthly maintenance. Peri-implantitis is the long-term risk, and it is manageable if it is looked for.
