The relationship between cigarette smoking and dental implant failure

This paper examines the effect of tobacco use on the failure rates of dental implants. A review of 56 dental implant patients with a total of 187 endosseous dental implants, placed over a four year period, demonstrated a significant association between increased implant failure rates and cigarette smoking with failure rates of 16.6% in smokers compared to 6.9% in non-smokers. Also implant length was shown to be a significant factor with shorter implants (< or = 10 mm) being more susceptible to failure in smokers. A chi-square test was used for data analysis. Current recommendations that should be given to implant patients who smoke are included.
