Abstract：Objective To investigate the impact of aesthetic zone root shielding technology on gingival crevicular fluid cytokines and the pink esthetic score(PES)of patients.Methods The clinical data of 72 patients(72 teeth)who underwent anterior tooth restoration in the First Affiliated Hospital of Zhengzhou University from April 2022 to April 2024 were retrospectively collected.These patients were divided into an observation group and a control group based on the restoration protocol,with 36 cases(36 teeth)in each group.The observation group was given aesthetic zone root shielding technique,while the control group was given conventional implant technique.Perioperative indicators and implant success rates were statistically analyzed for both groups,as well as the thickness of each point of the labial horizontal bone plate[implant shoulder(IS)]immediately after restoration,and at 6 and 12 months after restoration.Additionally,the levels of interleukin-6(IL-6),matrix metalloproteinase-2(MMP-2),interleukin-1β(IL-1β),plaque index(PLI),sulcus bleeding index(SBI),and probing depth(PD)in gingival crevicular fluid were compared before restoration,and at 6 and 12 months after restoration.Complications,PES and white aesthetic index(WES)were recorded at 12 months after repair.Results The duration of postoperative swelling and pain in the observation group was shorter than that in the control group(P＜0.05).At 6 months and 12 months after repair,the thickness of 0 mm-IS,3 mm-IS and 6 mm-IS sites of the lateral horizontal bone plate in the observation group was higher than that in the control group(P＜0.05).At 6 months and 12 months after repair,the levels of IL-6,MMP-2 and IL-1 β in gingival crevicular fluid in the observation group were lower than those in the control group(P＜0.05).At 6 months and 12 months after repair,PLI,SBI and PD in the observation group were lower than those in the control group(P＜0.05).There was no statistically significant difference in the incidence of complications between the observation group and the control group(P＞0.05).At 12 months after repair,the PES,WES and comprehensive aesthetic index of the observation group were higher than those of the control group(P＜0.05).At 12 months after repair,the implant success rate was 100％in both groups.Conclusion The use of root shielding technique in immediate implantation in aesthetic area can effectively maintain the stability of soft and hard tissues,maintain the health of periodontal tissues,and obtain good aesthetic effects.
