Tobacco smoking remains one of the most significant modifiable risk factors in modern implant dentistry. Numerous clinical and experimental studies confirm that tobacco exposure adversely affects bone metabolism, immune response, and vascularization of oral tissues. These effects are particularly critical in the context of dental implantation, where successful osseointegration and long-term peri-implant tissue stability are prerequisites for treatment success. In recent years, the widespread adoption of alternative nicotine delivery systems, including heat-not-burn (HNB) devices and electronic cigarettes, has created a false perception of reduced biological risk. However, accumulating evidence indicates that nicotine itself, regardless of delivery method, exerts vasoconstrictive, pro- inflammatory, and osteotoxic effects, which may compromise implant survival and increase the incidence of peri-implant diseases.
