Influence of dental implantation on periodontal index and implant retention in the treatment of dentition defect with periodontitis

Abstract

Objective To analyze the influence of dental implantation on periodontal index and implant retention in the treatment of dentition defect with periodontitis. Methods The clinical data of 103 patients with dentition defect who were treated in the Fourth People’s Hospital of Liaocheng from June 2017 to May 2018 were retrospectively analyzed. According to periodontal health, 53 patients (58 implants) with dentition defect complicated by periodontitis were set as observation group, while 50 dentition defect patients (54 implants) without periodontitis were set as control group. All the selected patients received dental implantation therapy. The periodontal indexes, including plaque index (PLI), periodontal depth (PD), gingival sulcus bleeding index (SBI), gingival papilla index (PIS), and implant retention rate were observed at different time points after operation in the two groups. Results PLI, SBI, PD and PIS of the two groups were not significantly different 1 month and 6 months after implantation (P>0.05). There was no statistically significant difference in implant retention rate between the two groups 6 months after implantation (P>0.05). Conclusions Dental implantation for patients with dental defect complicated by periodontitis has a relatively ideal short-term effect, by which periodontal index has no remarkable change and implant exfoliation rate will not increase.
