Abstract
Objective To observe the effect of jumping gap in immediate implant placement and provisionalization(IIPP)procedure on the stability of peri-implant soft tissues in patients with single tooth defect in the maxillary incisor region.Methods A total of 100 patients with single tooth defect in the maxillary incisor region who underwent IIPP procedure in the hospital from April 2021 to January 2023 were selected.According to different jumping gaps in IIPP procedure,subjects were divided into the control group(1.0-1.4 mm of jumping gap)and the observation group(1.5-2.0 mm of jumping gap),with 50 cases in each group.The stability of peri-implant soft tissues,morphology of periodontal soft tissues,dental aesthetic effects,and patient satisfaction in both groups were observed.Results After restoration using permanent crown and 1 year after restoration,implant stability quotient(ISQ)in the observation group was significantly higher than that in the control group(P＜0.05).Six months after restoration,interdental papilla index in the observation group was significantly better than that in the control group.The pink aesthetic score(PES)and white aesthetic score(WES)were significantly higher than those of the control group(P＜0.05).Compared with the control group,patients in the observation group were more satisfied with masticatory ability,stability,aesthetics,and comfort(P＜0.05).Conclusion Compared with 1.0-1.4 mm of jumping gap,adopting 1.5-2.0 mm of jumping gap in IIPP procedure can improve the stability of peri-implant soft tissues and morphology of periodontal soft tissues in patients with single tooth defect in the maxillary incisor region,and enhance the aesthetic effect and patient satisfaction.关键词
