The Outcome of Smoking on Healing of Bone Around Dental Implants

To assess the outcome of cigarette smoking and non-smoking on the healing of bone around dental implants. Materials and Method: A retrospective analysis was made over 6 years of the clinical and radiographic findings corresponding to 60 consecutive patients (25 women and 35 men) who had received a total of 100 implants. Patients were divided into two groups: smokers, 32 patients (received 50 implants); and non-smokers (NSs), 28 patients (received 50 implants). Smokers were identified as people smoking >15 cigarettes per day. The success and failure cases were evaluated and studied. The data were analyzed using descriptive statistics. Result: Smokers and NSs received 50 implants in each group with 5 (10%) and 2 (4%) failures and 90% and 96% of success in smokers and NSs, respectively. Smokers had a higher failure rate than NSs. The difference was statistically significant. Conclusion: The results indicated a higher success of implants in NSs compared to smokers.
