Aims: For replacement of missing teethosseointegrated implants are used. Survival rate of implant based on many aspectscomprising ofimplant material used, oral hygiene, personal oral habit such as smoking and bone quality. The current retrospective study was done to evaluate the consequence of smoking on survival of dental implant. Materials and Methods: The study subjects were included from all the patients who undertook for dental implant in implant center from 2012 to 2018. For every patient, severaldataconcerning implant characteristics and smoking habits were noted. The readings were statistically calculated by SPSS statistical software by IBM version 20with Chi-square test at P ≤ 0.01. Results: There was in that 128 (64%) smoker and 72 (36%) were non-smokers. More implants were placed in mandible (124 62%) compared to maxillary area (76 38 %). From 200 implants, total 181 were successful and 20 were failed. Success of implant was considerably more in nonsmokers 71 (98.6%) than smokers 110 (86%). Implant failure rate was more in smokers with greater frequency and duration of cigarette smoking habit. Conclusion: The current study shown that higher risk of implant failure and it wasrelatedto long term and increased frequency of smoking because of bone resorption.
