Abstract Purpose The aim of this 60 months follow‐up investigation was to investigate the impact of jaw location on clinical and radiological status of dental‐implant therapy in cigarette‐smokers and never‐smokers. Materials and Methods Twenty‐nine self‐reported cigarette‐smokers and 27 nonsmokers were assessed. All implants were categorized into three regions with reference to their location in the maxilla or mandible: ( a ) Anterior zone: implants located in anterior teeth; ( b ) Middle zone: Implants located in the premolar region; and ( c ) posterior zone: implants located in the molar region. Peri‐implant crestal bone loss (CBL), bleeding‐on‐probing (BOP) and probing‐depth (PD) ≥ 4 mm and were assessed. Level of statistical significance was set at P < .05. Results Mean age of cigarette‐smokers ( n = 29) and never‐smokers ( n = 27) was 44.5 years (39‐51 years) and 43.6 years (35‐49 years), respectively. The average duration of cigarette‐smoking was 20.3 years (17‐26 years). The mean periimplant PD ( P < .05) and CBL ( P < .05) were significantly higher in cigarette‐smokers in contrast to never‐smokers in all zones. No statistically significant differences in CBL, PD, and BOP were observed in the three zones of implant location among cigarette‐smokers and never‐smokers. Conclusion Smoking enhanced PD and CBL around dental implants and this relationship was independent of site of implant placement and jaw location.
