Abstract

BACKGROUND

The aim of this in vitro study was the evaluation of the mechanical properties the screws for rapid maxillary expansion (RME).

METHODS

Three commercially available screws for RME were tested: Leone A2620; Dentaurum Hyrax; Forestadent Palatal Split Screw. All expansion screws were 10 mm in size. For the evaluation of mechanical properties, the screws for RME were adjusted using the same maxillary dental model. An Instron 3365 testing machine with a load cell of 5 kN recorded the forces released by the screws at different amounts of activation (1, 5, 10, 15 and 20 quarters of a turn). Each type of screw was tested 10 times. Comparisons between the forces released by the different types of screws at different amounts of activation were carried out by means of analysis of Kruskal-Wallis test with post-hoc test di Tukey (P < 0.05).

RESULTS

The results of this study showed that all 3 expansion devices were able to develop forces that could produce a separation of the palatine processes. The Hyrax and A2620 expanders developed force values over 20 kg and the Palatal Split screws about 16 kg. Both the A2620 and Hyrax expanders showed significantly greater amounts of forces at all the different amounts of activations with respect to the Palatal Split screw.

CONCLUSIONS

All tested devices showed the capability of developing expansion forces (16-20 kg) adequate for RME. The A2620 and Hyrax expanders showed a greater level of rigidity than the Palatal Split screw.

摘要

背景

本体外研究旨在评估快速上颌扩张（RME）用螺丝的机械性能。

方法

对三种市售的 RME 用螺丝进行了测试：Leone A2620、Dentaurum Hyrax 和 Forestadent Palatal Split Screw。所有扩张螺丝的尺寸均为 10 毫米。为了评估机械性能，使用相同的上颌牙模来调整 RME 用螺丝。一台带有 5 kN 称重传感器的 Instron 3365 试验机记录了螺丝在不同激活量（1、5、10、15 和 20 四分之一转）下释放的力。每种类型的螺丝测试 10 次。通过 Kruskal-Wallis 检验和 Tukey 事后检验（P<0.05）对不同类型的螺丝在不同激活量下释放的力进行了比较。

结果

本研究的结果表明，所有 3 种扩张装置都能够产生足以分离腭骨的力。Hyrax 和 A2620 扩张器产生的力值超过 20 公斤，而 Palatal Split 螺丝约为 16 公斤。与 Palatal Split 螺丝相比，A2620 和 Hyrax 扩张器在所有不同激活量下都显示出明显更大的力值。

结论

所有测试的装置都显示出产生足以进行 RME 的扩张力（16-20 公斤）的能力。A2620 和 Hyrax 扩张器比 Palatal Split 螺丝具有更高的刚性水平。
