Orthodontic mini-implants are well-known anchorage devices and stand out as a particularly effective tool for ensuring maximum anchorage without relying on patient compliance. Therefore, it is necessary to understand what levels of torque strains remain in the physiological limits and can guarantee the stability of these mini-implants. The aim of this study was to investigate and measure the initial and final torque values of orthodontic mini-implants when placed perpendicular to the maxillary and mandibular bone surfaces. In our study, orthodontic mini-implants from different companies were inserted perpendicularly using different insertion torques on the plate of both maxillary and mandibular bones from pig specimens. The torque values were then analyzed. The results of this study highlight the need for continued research to analyze the ideal insertion torque of different types of mini-implants depending on the insertion area, in order to achieve clinical success of mini-implants.
正畸微型种植体是众所周知的锚固装置，并且作为一种特别有效的工具脱颖而出，它无需依靠患者的配合就能确保最大程度的锚固。因此，有必要了解在生理限度内仍能保持何种扭矩应变水平，并能保证这些微型种植体的稳定性。本研究的目的是调查和测量正畸微型种植体垂直于上颌骨和下颌骨表面植入时的初始和最终扭矩值。在我们的研究中，使用不同的插入扭矩将来自不同公司的正畸微型种植体垂直插入猪标本的上颌骨和下颌骨板中。然后对扭矩值进行分析。本研究结果突出表明，需要继续开展研究，根据植入区域分析不同类型微型种植体的理想插入扭矩，以实现微型种植体的临床成功。
