Aim and objective:
For permanently replacing missing teeth, dental implant placement is a common treatment procedure in dentistry. The success rates of implants depend on the presence of healthy surrounding tissue and finally amount of marginal bone levels. In this study we aimed to compare marginal bone loss around implants in implant supported removable prosthesis in smokers and non smokers.

Records of 64 non-smoker, and 19 smoker pateients were collected from 166 implants in routine recall sessions 6, 12, and 24 months after loading. The collected data consisted of gender, age, implant diameter, implant length and periodontal parameters (plaque index, gingival index and pocket probing depth). Marginal bone measurements was analized using digitized periapical dental images. Statistical analysis was performed using the SPSS 22.0 version.The results were assessed at 95% confidence interval, at a significance level of 0.05.

Marginal bone loss was affected by the smoking and severity of loss was increased signficantly from 6 to 24 months (p< 0.05) in smokers. Age was also significantly related to marginal bone loss, while, there was no significant relationship between marginal bone loss and gender or implant length or diameter (p>0.05). Plaque index and probing depth was higher in smokers, while gingival index was higher in non-smokers.

Implants used for removable prosthesis in the elderly smokers may be at higher risk to present marginal bone loss leading to loss of implants.
