Abstract:
Objective:To investigate the functional and structural recovery of posterior teeth in patients with chronic local periodontitis after single implant restoration.Methods:A total of 133 patients with tooth loss who need single posterior tooth fixation and implantation in Shaoxing People's Hospital from January to December 2019 were included in this study. These patients were divided into periodontitis ( n = 40) and periodontitis-free ( n = 93) groups according to whether they had chronic local periodontitis. All patients were followed up for 6 months. Probing depth (PD), gingival thickness, papilla index score (PIS), modified sulcus bleeding index (mSBI) and marginal bone resorption were compared between the two groups at 1, 3 and 6 months after implant repair. The success rate of tooth implant was compared between the two groups. Results:There was no significant difference in success rate of tooth implant between periodontitis and periodontitis-free groups [100.0% (93/93) vs. 95.0% (38/40), χ2 = 1.94, P = 0.163]. There was no significant difference in the incidence of postoperative complications between periodontitis and periodontitis-free groups [0.0% (0/93) vs. 2.5% (1/40), χ2 = 0.19, P = 0.663]. In the periodontitis group, PD was significantly greater at 3 and 6 months after surgery than that at 1 month after surgery ( t = 2.31, 4.30, P = 0.020, < 0.001). In the periodontitis group, mSBI was lower at 6 months after surgery than that at 1 month after surgery ( t = 1.97, P = 0.048). In the periodontitis-free group, mSBI was lower at 3 and 6 months after surgery than that at 1 month after surgery ( t = 3.64, 4.50, both P < 0.001). There were significant differences in PD and mSBI between periodontitis and periodontitis-free groups at 6 months after surgery ( t = 2.06, 2.13, P = 0.041, 0.035). At 6 months after surgery, marginal bone resorption in both periodontitis and periodontitis-free groups improved compared with that immediately after surgery. In the periodontitis group, marginal bone resorption at 1 month after surgery was not significantly different from that at 3 and 6 months after surgery ( t = 1.64, 0.63, P = 0.100, 0.524). In the periodontitis-free group, marginal bone resorption at 1 month after surgery was not significantly different from that at 3 and 6 months after surgery ( t = 1.70, 1.18, P = 0.088, 0.236). In the periodontitis group, gingival thickness at 1 month after surgery was not significantly different from that at 3 and 6 months after surgery ( t = 0.99, 0.49, P = 0.321, 0.620). In the periodontitis-free group, gingival thickness at 1 month after surgery was not significantly different from that at 3 and 6 months after surgery ( t = 0.87, 1.36 P = 0.379, 0.173). Gingival thickness and marginal bone resorption at 1 month after surgery were not significantly different from those at 3 and 6 months after surgery in each group ( t = 0.49, 0.39, 0.54, 0.77, 0.55, 0.38, P = 0.623, 0.693, 0.590, 0.439, 0.580, 0.699). Conclusion:Single implant restoration exhibits good short-term effects on tooth loss combined with chronic local periodontitis. Single implant restoration does not have a great impact on gingival thickness and marginal bone absorption, but it leads to a higher incidence of peri-implantitis in patients with periodontitis than in patients with healthy periodontal tissue.
