Abstract: Objective： To explore the clinical effect on patients with immediate repair without flap in anterior teeth. Methods： A total of 45 patients undergoing anterior tooth restoration were enrolled in this study. All patients were admitted to the hospital from December 2016 to October 2017. Random number table was used to divide them into 23 cases in the control group and 22 cases in the observation group example. The patients in the control group were repaired with conventional flap inversion technique, and the pa- tients in the observation group were treated with immediate implant repair without flap. The red aesthetic index (PESN), alveolar bone resorption and implant success rate, Repair satisfaction, postoperative stabili- ty(ISQ), and other clinical indicators were compared between the two groups. The clinical effects of the two groups of patients after treatment were evaluated side by side according to the gingival papilla filling index(PIS). At the same time, the adverse symptoms of two groups of patients were recorded and com-pared. Results： Compared with the control group, the corresponding index data of the observation group was higher than that of the control group(P<0.05), and the alveolar bone resorption of the observation group was lower than that of the control group. The results were statistically significant(P<0.05), the suc- cess rate of implantation and the satisfaction degree of repair were higher in the observation group than in the control group(P<0.05). PIS index in observation group 0 and 1 degrees were significantly higher than the control group, the difference was statistically significant(P<0.05). The incidence of adverse symptoms in the observation group was significantly lower than that in the control group, the difference was statisti- cally significant(P<0.05). Conclusion： The effect of immediate implantation without flap is significant, which is beneficial to the patients' soft tissue shape, stability and success rate after implantation, so it is worth popularizing in clinic.
