Abstract

Abstract: Objective: To study whether over-preparation method can improve the accuracy of implant placement in the maxillary anterior region. Methods: Forty cases (40 implant sites) of immediate implantation were enrolled in this study and divided into two groups (n=20, each group): those who received routine guided implant surgery were control group and those who received implant surgery with over-preparation (OP) method were test group. The insertion torque and the actual position of the dental implant were recorded during the operation. The implant platform, apex, and angle deviations from each of the planned positions were calculated. Results: In the control group, the mean platform, apex, and angulation deviation were (0.68±0.28) mm, (2.48±0.50) mm, and (4.35±1.19)°, respectively. In the test group, the mean platform, apex, and angulation deviation were (0.48±0.25) mm, (1.05±0.54) mm, and (2.09±0.70)°, respectively. There was significant differences between two groups (P＜0.05). However, there were not significant difference in the primary stability between two groups (P>0.05). Conclusion: The over-preparation method can reduce the influence of palatal bevel of teeth extraction socket and improve immediate implant placement accuracy in the maxillary anterior region.
