A comparative study of implant survival rates in smokers and non-smokers

Smoking has been implicated as a potential risk factor compromising the success of dental implant therapy, yet its precise impact on implant survival remains inconsistently reported. Therefore, it is of interest to evaluate implant survival rates and peri-implant outcomes in 100 participants, equally divided into smokers and non-smokers. Standardized surgical protocols were followed and clinical and radiographic assessments were performed over a 12-month follow-up period. Implants in smokers showed lower survival rates, increased marginal bone loss and a higher prevalence of peri-implant complications compared with non-smokers. This study advances knowledge by providing controlled comparative evidence that reinforces smoking as a significant determinant of reduced implant survival and peri-implant health.
