Abstract: Objective: To investigate the clinical effect of Planting restorationin chronic periodontitis patients. Methods: 96 cases of Planting restorationpatients who were treated in our hospital were selected as the research object, including 48 healthy periodontal patients as the control group and 48 patients with chronic periodontitis as the study group. Both groups were treated with dental implantation. PD(probing depth), mPLI(modified plaque index), mSBI(modified gum crevicular bleeding index) was compared of the two groups after treatment for 3 months, 6 months and 12 months, and Implantation restoration and alveolar bone resorption in 3 years and 5 years in the two groups. Results: Increase with time after planting and restoration, the level of PD, mPLI, mSB were increased, the PD in the study group was significantly higher than the control group (P<0.05), there was no significantly different of mPLI in the two groups(P>0.05), the mSBI in 3 months of the two groups was not significantly different(P>0.05), and the mSBI in the study group was significantly higher than the control group at 6 and 12 months (P<0.05). The implantation restoration in the control group was higher than the study group, but there was no significant difference between the two groups in half a year and one year(P>0.05). The implantation restoration in the control group was significantly higher than the study group at 3 and 5 years (P<0.05). The alveolar bone resorption in the study group for 3 years and 5 years was significantly higher than the control group(P<0.05). Conclusion: The short-term effect of implantation repair on chronic periodontitis patients is better, the long-term effect is significantly lower than the healthy periodontal patients due to inflammatory reaction.
