Objective:To compare the effect and complications of immediate and delayed restoration after immediate implantation in the anterior tooth region of elderly patients with periodontal disease.Methods:A total of 86 elderly patients with periodontal disease who underwent anterior dental restoration admitted to the Second People′s Hospital of Huai′an from February 2019 to August 2021 were prospectively selected and divided into observation group ( n=43) and control group ( n=43) according to the order of admission. Both groups received immediate implantation, the observation group received immediate repair after surgery, the control group received delayed repair after surgery. Both groups were followed up for 12 months after implantation. The soft tissue around the implant, White Aesthetic Score (WES), Pink Esthetic Score (PES), bone resorption value, implant success rate and complications were compared between the two groups. Results:One month after repair, periodontal probing depth (PD) in observation group was lower than that in the control group ( P<0.05), and modified sulcus bleeding index (mSBI) was higher than that in the control group ( P<0.05). At 3 months after repair, PD in both groups was lower than that at 1 month after repair (all P<0.05), and PD in the observation group was lower than that in the control group ( P<0.05), while mSBI in the observation group was lower than that at 1 month after repair ( P<0.05), and there was no statistical significance between the two groups ( P>0.05). Six months after repair, WES scores and PES scores in the observation group were higher than those in the control group ( P<0.05). At 6 months after repair, the bone resorption value of the observation group was lower than that of the control group ( P<0.05). At 12 months after repair, the bone resorption values of both groups were higher than those of 6 months after repair (all P<0.05), and there was no statistical significance in the bone resorption values of the two groups at 2 months after repair ( P>0.05). At 12 months after implantation, there was no significant difference in the success rate between the two groups ( P>0.05). The total incidence of complications in the observation group (6.98%, 3/43) was lower than that in the control group (27.91%, 12/43) ( P<0.05). Conclusions:Immediate repair and delayed repair are effective in the restoration of the anterior tooth region in elderly patients with periodontal disease. Compared with delayed repair, immediate repair can reduce the alveolar bone absorption of patients, improve the soft tissue health around the implant, have better aesthetic effects, and reduce the risk of complications.
