Introduction: Wound healing is fundamental to the process of osseointegration and smoking is recognized as a risk factor. Several mechanisms have been proposed by which smoking may affect wound healing. The development of osseointegrated implants represents one of the most important breakthroughs in contemporary dental practice in the oral rehabilitation of partially or fully edentulous patients.
Aim: The aim of this retrospective study is to compare the osseointegration of implants with two kinds of surfaces in smokers and non-smokers.
Materials and Methods: Patients - smokers and non-smokers, with implant treatment for at least 3 years, were divided into four groups with 25 patients in each group. Their implant placement was made following the same protocol, by one operator and after that they received same instructions.
Results and Discussion: Both osseointegration and good healing of the mucosal structures are required for dental implant placement to be successful.
Conclusion: Smoking is one of the factors contributing to implant failure. It imposes multiple effects on the oral mucosa. The soft tissues around implants with two kinds of surfaces showed stable healing between smokers and non-smokers, with no great difference.
