〔Abstract〕 Objective To observe the clinical effect of dental implant restoration treatment in patients with chronic periodontitis. Methods 82 patients who underwent dental implant restoration in Changsha Stomatological Hospital from July 2018 to July 2019 were randomly selected and divided into two groups according to whether they had chronic periodontitis. The control group was 41 cases without chronic periodontitis. Patients in the observation group consisted of 41 patients with chronic periodontitis. The related indicators, alveolar bone resorption and implantation success rate after treatment were compared between the two groups. Results After dental implant restoration treatment, the PISF of the observation group was (0.61 ± 0.19) μL, the mBI was (1.14 ± 0.24), and the PPD was (2.45 ± 0.35) mm, which were better than those of the control group, and the difference was statistically significant (P < 0.05) ; The alveolar bone resorption of the observation group was (0.41 ± 0.24) mm after half a year and (0.66 ± 0.11) mm after one year, which were better than those of the control group, and the difference was statistically significant (P < 0.05); the half-year implantation success rate of the observation group was 92.68%, and the 1-year implantation success rate was 90.24%, both higher than 75.61% and 70.73% of the control group. The difference was statistically significant (P < 0.05). Conclusion For patients with chronic periodontitis, dental implant restoration treatment has better alveolar bone resorption and a higher implant success rate.
