Aims and Objectives: Osseointegrated implants are used in replacement of missing teeth. Survival rate of implant depends on many factors including oral hygiene, implant material used, bone quality, and personal oral habit such as smoking. The present retrospective research was conducted to assess the effect of smoking on survival of dental implant. Materials and Methods: The study participants were selected from all the patients who underwent for dental implant in implant center from 2005 to 2015. For each patient, various information regarding implant characteristics and smoking habits were recorded. The readings were statistically evaluated by SPSS statistical software by IBM version 21 and using Chi-square test at P ≤ 0.01. Results: In our study, the age range of patients was between 30 and 54 years. There were 2142 (57.2%) male and 1579 (42.4%) female participants, in that 72.2% were nonsmokers and 27.7% were smokers. Implant placed more in mandible (2312, 62%) than in maxillary region (1409, 37.8%). From 3721 patients, 3600 were successful and 121 failures. Success of implant was considerably more in nonsmokers than smokers. Implant failure rate was more in smokers with increased frequency and duration of cigarette smoking habit, but it was statistically not significant. In the present study, we have observed 0.049% mobility in smokers compared to 0.007% in nonsmokers. Conclusion: The present study showed that higher risk of implant failure was associated with long term and increased frequency of smoking due to bone resorption.
