Title Smoking and Dental Implant Treatment
Clinical Question How does the prognosis for dental implant placement compare between smokers and nonsmokers?
Clinical Bottom Line Evidence shows that the success of dental implant treatment is significantly affected by smoking. A smoker is two times more likely to experience an implant failure than a nonsmoker. (See Comments on the CAT below)

Comments on
The Evidence
The definition of a smoker varied between the studies, so the authors decided to define a smoker as anyone who smokes. The explanation of the results might be more straightforward if they were expressed as a comparison of percent failures or successes.
Applicability The results are relevant to any smoker seeking dental implant treatment.
