摘要/Abstract

摘要： 目的: 研究过预备法对上颌前牙区即刻种植精度的影响。方法: 选择40例上颌前牙区接受即刻种植治疗的患者纳入试验。试验组(n=20)在全程种植导板的引导下进行种植外科手术,并联合使用过预备法对拔牙窝腭侧骨壁进行修整;对照组(n=20)仅在全程种植导板的引导下进行种植外科手术。术中记录各组种植体的初期稳定性及三维位置,术后比较各组种植体实际三维位置与术前规划间的差异。结果: 试验组种植体的颈部偏差为(0.48±0.25) mm、根尖部偏差为(1.05±0.54) mm、角度偏差为(2.09±0.70)°;对照组种植体颈部偏差为(0.68±0.28) mm、根尖偏部差为(2.48±0.50) mm,角度偏差为(4.35±1.19)°。两组种植体的颈部偏差、根尖部偏差、角度偏差间差异均具有统计学意义(P＜0.05),两组种植体的初期稳定性间差异不具有统计学意义(P＞0.05)。结论: 过预备法能够减小拔牙窝腭侧骨壁对于种植体三维位置的影响,提高上颌前牙区即刻种植的精确度。

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.
