Abstract

Abstract: Objective: To explore the influence of emergence profile of crown on the occurrence of peri-implantitis for bone level implants, and to verify the feasibility of using emergence profile of crown as risk factor of peri-implantitis through clinical examination, imaging examination, and biomarker detection. Methods: There were 91 bone level implants in 90 patients in the experimental group, which were divided into convex group (29 cases), straight group (36 cases), and concave group (26 cases) according to the emergence profile of the crown. The control group consisted of 35 homonymous healthy natural teeth on the opposite site. The periodontal and imaging examinations were recorded, and the levels of RANKL, OPG, IL-10, and IL-1β in gingival crevicular fluid of each group were detected by ELISA. Results: There were statistical differences in PD and SBI among convex PI group, straight PI group, concave PI group, and control group (P<0.05). The levels of RANKL, IL-1β, OPG, IL-10, and the ratio of RANKL/OPG in convex PI group, straight PI group, concave PI group, convex healthy group, straight healthy group, and concave healthy group were significantly different from those in the control group (P<0.05). The prevalence of PI in the convex group was higher than that in the straight group and concave group (P<0.05). Conclusion: Convex emergence profile is more likely to cause peri-implantitis than straight and concave emergence profile. A combination of clinical examination, imaging examination, and biomarker detection is more accurate to indicate the influence of emergence profile on early peri-implantitis.
