Abstract

OBJECTIVE

To evaluate factors (root proximity and cortical bone thickness) affecting the success rate of orthodontic micro-implants (OMIs) using cone-beam computed tomography (CBCT) images.

MATERIALS AND METHODS

We examined 172 OMIs (1.2-1.3 mm in diameter, 8 mm in length) implanted into the maxillary buccal alveolar bone of 94 patients (33 men, 61 women) with malocclusion. Root proximity and cortical bone thickness were measured, and the correlations between these measurements and OMI success rates were evaluated.

RESULTS

The overall success rate was 90.7% (156/172). The success rate increased as the distance between the root surface and OMI increased, showing a highly significant statistical correlation (P < .05). As the cortical bone thickness increased, the success rate increased, showing a slight, nonsignificant correlation (P > .05). Thus, the success rate of OMIs was affected more significantly by root proximity than cortical bone thickness.

CONCLUSIONS

When inserting OMIs, increasing the distance from the OMI to the root surface will significantly improve success rates.

摘要

目的

使用锥形束计算机断层扫描（CBCT）图像评估影响正畸微种植体（OMI）成功率的因素（根近和皮质骨厚度）。

材料与方法

我们检查了 94 名错畸形患者（33 名男性，61 名女性）上颌颊侧牙槽骨中植入的 172 颗直径 1.2-1.3 毫米、长 8 毫米的 OMI。测量了根近和皮质骨厚度，并评估了这些测量值与 OMI 成功率之间的相关性。

结果

总体成功率为 90.7%（156/172）。随着根表面与 OMI 之间距离的增加，成功率增加，具有高度显著的统计学相关性（P<.05）。随着皮质骨厚度的增加，成功率增加，呈轻微但无统计学意义的相关性（P>.05）。因此，OMI 的成功率受根近的影响比皮质骨厚度更显著。

结论

在植入 OMI 时，增加 OMI 与根表面的距离将显著提高成功率。
