Dental implant replacement therapy render fabrication of implant supported or retained prosthesis with excellent prognosis even in the compromised bony conditions where typical removable or fixed prosthesis fails. Hence; the present study was undertaken for assessing the prognosis of dental implants in smokers and diabetics.
Materials & methods: A total of 200 subjects were enrolled in the present study and were divided into four study groups with 50 patients in each group as follows: Group 1: Smokers and non-diabetic Group 2: Diabetic and non-smoker, Group 3: Smokers and diabetic, and Group 4: Controls. Only those patients were enrolled who had missing mandibular first permanent molar and were scheduled to undergo prosthetic rehabilitation by dental implants. All the dental implant procedures were commenced under the hand of skilled and experienced surgeons. Follow-up was done upto a time period of 2 years and prognosis of dental implants was recorded.
Results: Success rate of dental implants among patients of group 1, group 2, group 3 and group 4 was found to be 82%, 94%, 80% and 96% respectively. Significant results were obtained while comparing the prognosis of dental implants among group 1 and group 2, group 1 and group 4, group 2 and group 4, and group 3 and group 4 respectively.
Conclusion: Smoking and presence of diabetes as a co-morbid condition are significant risk factors of dental implant failure.
