Abstract: Objective: To compare and analyze the clinical effects of immediate implant repair and delayed im-plant repair of maxillary single front teeth. Methods: A retrospective analysis from April 2015 to April 2016 in our hospital treatment of 72 cases of maxillary anterior teeth. According to single patients were randomly divided into observation group and control group, two groups of 36 cases in each. The patients in control group was given delayed implant treatment, the observation group was given immediate implant treatment in the two groups. With 12 months of follow-up were compared between two groups. The suc-cess rate of dental implant, 1 months, 12 months after the classification of gingival aesthetics and the depth of periodontal pocket implant, subjective satisfaction after 12 months were compared. Results: The observation group and the control group of success rate was 100%(36/36), the comparison between the two groups was not statistically significant(P>0.05). The observation group 1 months after implant restoration, gingival aesthetics grading scores after 12 months respectively (8.92±1.31), (8.41±1.38), which were sig-nificantly higher than the control group (8.13±1.22), (7.73±0.87)(P< 0.05). The observation group of im-plant after 1 months, 12 months after periodontal pocket depth levels were (1.38±0.22) mm, (1.49±0.36) mm, which was significantly lower than the control group (3.71±0.08) mm, (2.02±0.14)mm(all P<0.05). The patients in the observation group were chewing function, attachment height and overall appearance satisfaction scores were (8.74±0.64), (8.74±1.24), (8.81±1.28), were significantly higher than that in the control group (6.67±1.32), (7.38±0.68), (7.56±1.32)(P<0.05). Conclusion: Immediate implantation and delayed implant treatment of maxillary anterior teeth single success rate, but the immediate implant in im-proving patients with gingival aesthetic grade and depth of periodontal pocket has better effect, can im-prove the subjective satisfaction of patients.
