Abstract: PURPOSE: To evaluate the effect of flapless immediate tooth implantation for maxillary anterior teeth. METHODS: Eighty-eight patients treated from September 2014 to August 2015 in our hospital were collected. They were randomly divided into experimental group and control group, 44 cases in each group. Patients in the control group underwent traditional immediate tooth implantation, while patients in the experimental group underwent flapless immediate tooth implantation. The operation time, the survival rate of the implant, alveolar bone health, satisfaction, aesthetics, and postoperative symptoms in 2 groups were recorded and compared. SPSS 11.5 software package was used for data analysis. RESULTS: The operation time in the experimental group was significantly shorter than the control group, which was (29.34±2.42)min vs (55.32±3.54) min; alveolar bone in the experimental group was significantly superior to the control group(P<0.05), which was (0.84 ±0.04) mm vs (1.21±0.07) mm; the survival rate of the experimental group was significantly higher than the control group(P<0.05), which was 93.18% (41/44) vs 72.73% (32/44). After treatment, VAS score and PES score in the experimental group were significantly higher than the control group, which was (8.32±0.42) vs (5.78±0.24), (11.24±0.43) vs (8.45±0.58), respectively(P<0.05). The incidence of postoperative pain, redness and swelling, bleeding in the experimental group was significantly lower than control group, which was 18.18% (8/44) vs 38.64% (17/44), 15.91% (7/44) vs 34.09% (15/44) and 11.36% (5/44) vs 29.55% (13/44), respectively(P<0.05). CONCLUSIONS: Flapless dental implantation can improve the satisfaction of patients with dental implants, aesthetic, and success rate of implantation, reduce operation time, pain, and incidence of postoperative pain, redness and other symptoms.
