Abstract

Background:  Smoking habits either bidi or cigarette has a impact on survival rate of implant. Cigarette smoking results into impaired wound healing, leading to accelerated bone resorption, increased bone loss rate and reduced bone height of the alveolar ridge. The present study was conducted to assess the effect of smoking on implant success.  Materials & Methods: This study was conducted in department of Prosthodontics from year 2010 to 2012. It included 100 patients of both genders. Patients were divided into 2 groups. Group I {(Smoker(S)} – It included 50 patients and group II {(Non smoker (NS)} - It included 50 patients. A total of 100 implants were placed in 100 patients. Implant failure rate was assessed in both groups. Results: Out of 100 patients, group I had 50 (males- 25, females- 25). Similarly group II had 50 (males- 25, females- 25). The difference was non – significant (P > 0.05). Patients < 40 years had 25 males and 25 females. Similarly age group 41-60 years had 25 males and 25 females. The difference was non – significant (P > 0.05). Implant with diameter < 3.75mm was placed in 15 males and 15 females. Implants with diameter 3.75- 4.5mm was placed in 20 males and 25 females. Implants with diameter >4.5mm was placed in 15 males and 10 females. The difference was non- significant (P > 0.05). Implants with < 10mm were placed in 13 males and 10 females, 10-11.5mm was placed in 25 males and 20 females, similarly > 11.5mm was placed in 12 males and 20 females. The difference was non significant (P > 0.05). In group I, 5 implants (10%) showed implant failure. Similarly, in group II, 2 patients (4%) showed failure. The difference was significant (P < 0.05). Conclusion: Smoking has a deleterious effect on implant survival rate. Smokers are more prone to developed failure and complications. We found 10% of implant failure in our study.
