The Effect of Smoking on Marginal Bone Loss Around Dental Implant

Abstract

Background: Peri-implant marginal bone loss has been related to many factors such as patient age at the time of implantation, smoking, implant location, and systemic disease. Perhaps smoking is one of the main causes for the failure of the dental implant according to its  prevalent in our society.

comparing marginal implant bone loss (MBL) by radiographic evidence of dental implant among smokers and non-smokers.

Material and Methods: the sample consist of 32 patients aged between (20 to 45) years, treated with a total of 36 implants. Patients were divided into three groups: nonsmokers, smokers, and heavy smokers, the influence of smoking and other variables on MBL was analyzed at all implant site by panoramic radiographs through comparing the radiographs before and one year after loading the implants.

Results: shows that smokers had more MBL than non-smokers (0.15 mm, and 0.040 respectively. When each jaw was examined separately, smoking had a greater effect on MBL in the maxilla than mandible (0.15, and 0.14) respectively. Furthermore in the maxilla heavy smokers had the greatest amount of MBL (0.18mm) followed by smokers (0.15mm) and heavy smokers (0.13mm)in the mandible.

Conclusion: our study demonstrated a relationship between MBL and smoking habits, a higher incidence of MBL was found in the smoking group, and was more pronounced in the maxilla.
