Tobacco smoking is associated with a wide range of well documented health risks including compromised wound healing. Studies on dental implants indicate a higher rate of early and late implant failures in smokers compared to non-smokers. Additionally, smoking is a risk factor for peri-implant marginal bone loss.

Nevertheless, knowledge on the mechanisms behind the deteriorating effects of smoking on Osseo-integration.

Our study in periodontitis susceptible patients found significantly larger loss of turned implants in smokers compared to never-smokers. Interestingly, no significant difference in implant survival or marginal bone loss was observed at oxidized surface in smokers and never-smokers. This implies that oxidized surface implants are more suitable for periodontitis susceptible smoking patients.
