Adhesion remains a key element in dentistry, whether approached in prosthetics, odontology, or orthodontics. It is a continuously researched aspect, as improved materials and adhesive methods keep emerging in the market. No orthodontic treatment can be effective without the proper adhesion strength of the bonded elements on the teeth. The objective of this research, in the broad context of self-ligating versus conventional brackets, was to compare active and passive self-ligating systems with a conventional one by conducting an in vitro study on human-extracted premolars. Shear bond strength tests were executed by means of an advanced materials-testing machine that generated maximum load and tensile strength values. The data obtained underwent statistical analysis with a statistical threshold of p < 0.05. The results regarding the statistical significance were acquired when comparing the passive self-ligating system with the active self-ligating and conventional systems (load-at-maximum-load mean 204.9, SD 91.09, and p < 0.05). In this study, the passive self-ligating bracket system appears to present increased shear bond strength.
无论是在修复学、牙科学还是正畸学领域，粘结在牙科中仍然是一个关键因素。由于市场上不断涌现出改进的材料和粘结方法，这是一个持续研究的方面。如果牙齿上粘结部件没有适当的粘结强度，任何正畸治疗都不会有效。在自锁托槽与传统托槽的大背景下，本研究的目的是通过对拔除的人类前磨牙进行体外研究，将主动和被动自锁系统与传统系统进行比较。通过一台先进的材料试验机进行剪切粘结强度测试，该试验机可生成最大载荷和拉伸强度值。所获得的数据进行了统计学分析，统计阈值为p < 0.05。在将被动自锁系统与主动自锁系统和传统系统进行比较时，获得了关于统计学显著性的结果（最大载荷时的载荷平均值为204.9，标准差为91.09，p < 0.05）。在本研究中，被动自锁托槽系统似乎具有更高的剪切粘结强度。
