Application value of non-flapping technique in immediate implant prosthesis in aesthetic area of anterior teeth / 中国基层医药

ABSTRACT

Objective@#To explore the application value of non-flapping technique in immediate implant prosthesis in aesthetic area of anterior teeth.@*Methods@#From March 2016 to September 2017, 104 patients who received immediate implant restoration of anterior teeth in the First Hospital of Jiaxing were divided into observation group (53 cases) and control group (51 cases) according to random number table method.The control group was treated with conventional flap immediate implantation, while the observation group was treated with non-flap immediate implantation.The red aesthetic index (EPS), alveolar bone resorption and patients' satisfaction were compared between the two groups.@*Results@#The PES scores of the observation group were (6.17±1.21)points, (5.94±1.03)points and (5.12±0.85)points, respectively after repair 3 months, 6 months and 12 months, which were significantly higher than those of the control group [(5.38±0.96)points, (4.79±0.76)points, (4.05±0.70)points] (t=3.679, 6.459, 6.993, all P<0.05). At 3 months, 6 months and 12 months after restoration, the alveolar bone resorption in the observation group was(0.29±0.04)mm, (0.63±0.12)mm, (1.07±0.17)mm, respectively, which was significantly lower than that in the control group [(0.36±0.07)mm, (0.95±0.24)mm, (1.28±0.26)mm] (t=6.291, 8.649, 4.893, all P<0.05). At 12 months after repair, the satisfaction rate of patients in the observation group was 98.11% (52/53), which was significantly higher than 84.31% (43/51) in the control group (χ2=4.637, P<0.05).@*Conclusion@#The application of non-flapping technique in immediate implant prostheses in aesthetic area of anterior teeth has good effect, which can obtain better aesthetic effect, reduce alveolar bone absorption and improve patients'satisfaction with prostheses.However, in clinical work, it is necessary to strengthen preoperative examination and measurement of patients, accurately grasp the direction of implants and avoid the occurrence of bone wall perforation during operation.
