Abstract: Objective: To study the double disc not immediate implant prosthesis to the curative effect of 48 pa-tients and the influence of red aesthetic index(PES) score. Methods: Selected from February 2013 to Au-gust 2014 in our line of single tooth immediate implant prosthesis treatment of 96 cases of patients.Ac-cording to random number table method was divided into observation group and control group, 48 cases in each group. The control shall be double disc immediate implant prosthesis treatment, observation group adopts double disc immediate implant prosthesis treatment. Respectively, compared two groups of plant-ing success rate, the rate of bleeding, pain, redness and swelling rate, ratio, PES score before and after the treatment, 1 year, 2 years after the repair of bone absorption and patient satisfaction. Results: The obser-vation group of planting survival rate was 100.00%(48/48), higher than that of control group 84.00%(43/48), and the incidence of bleeding, swelling and pain were lower than the control group, with significant difference(P<0.05). Two groups of PES grading after treatment respectively (12.5±1.4),(9.9±2.1), were higher than before the treatment, the observation group was higher than that of control group, with signifi-cant difference(P<0.05). Observation group 1 year, 2 years later after the restoration of bone absorption, respectively was(0.50±0.03)mm, (0.53±0.03)mm, were lower than the control group (0.60±0.60) mm, (0.66±0.04) mm, with significant difference (P<0.05). Observation group of satisfaction was beautiful, comfortable satisfaction were 97.92%(47/48), 95.83%(46/48), higher than that of control group 85.42% (41/48), 81.25% (39/48), with significant differences (all P<0.05). Conclusion: Don't double disc imme-diate implant prosthesis effect significantly, can significantly improve the PES grading, improve patient
