Introduction: Dental implant therapy is a treatment of choice in the absence of teeth. However, certain conditions such as smoking, hypertension and diabetes have a negative influence on the success of dental implants. Nicotine can cause osteoclastic changes. The present study was carried out to assess the relationship between nicotine and implant failure. Materials and methods: The present retrospective study included 2570 patients of both sexes. They were divided into two groups. Group I consisted of 1250 patients with a history of smoking and group II non-smokers and 1320 patients. The presence of pain, mobility and inflammation was considered a positive sign for implant failure. Results: The results showed that in group I, men had 6.13% and women, 5%, dental implant failure. The overall failure rate in group I was 5.56%. In group II, males had 2.98% and females, 0.9% of failure. The general failure rate in group II was 2.35%. The difference between the two groups was statistically significant (P <0.05). In group I, maximum (56), and in group II, 18 patients had a habit> 10 years of smoking. The maximum number of patients had a consumption habit> 20 cigarettes / day (Group I) and Group II had only 10 patients with this frequency. Maximum failures were observed in the dental implant in the maxillary arch (70) than in the mandibular arch (32). The difference was statistically significant (P <0.05). Conclusion: Smoking influences the survival rate of dental implants. Thus, the patient must be educated to stop the habit before placing the implant.
