If you are undergoing any form of implant surgery, you must not smoke at all. Smoking is known to significantly reduce the chances of successful implant surgery, particularly during the 3-6 months that are required for implants to integrate.

Generally you will not be treated for implant surgery unless you have given up smoking for at least 3 months beforehand. Long-term, once the implants have healed, smoking is still considered a significant disadvantage, causing an increased risk of long-term implant loss.
