Background-Survival of the dental implant depends upon the oral health status and it has been observed that in patients with periodontitis, have more chances of peri‑implantitisly decades of age in systemically healthy patients. Transition in the field of dentistry replaced the removable partial dentures to fixed partial dentures to dental implants. Dental implants have brought boom in the field of dentistry, with replacing few teeth to several which gained importance in past few years. Aim and objectives- The aim and objective of the present study is to determine correlation between implant failure and periodontitis. Material and method- The study was conducted on 50 patients which involves both the genders with 80 dental implants in department of implantology. It was a retrospective study from January 2016- January 2019. Informed consent was obtained from the participants and ethical clearance was obtained from the ethical committee. Results- Out of 50 patients, males were 29 and females were 21. In 29 males, 50 dental implant and in 28 females, 30 dental implants were present. The difference was significant (P = 0.01) [Table 1]. Table 2 shows periodontal depth (mean ± S.D) around implant (4.22 ± 1.14), adjacent teeth (3.21 ± 1.06), and contralateral teeth (3.02 ± 0.24), it was statistically significant (p=0.01). Conclusion- Periodontal health strongly affects the outcome of dental implant therapy and the teeth adjacent to dental implant also plays an important role in deciding the success or failure of implant while the contralateral teeth have no strong relationship between peri‑implantitis and periodontitis.
