Abstract

Temporary anchorage devices (TADs) are orthodontic mini-implants with remarkable characteristics that, once inserted, present mechanical retention (primary stability) without the process of bone osseointegration. However, interaction with the biological environment may cause changes in the morphology of the external surface of dental TADs. In this study, we used 17 TADs made of aluminum-vanadium titanium alloy, produced by two companies, which were analyzed through optical microscopy after being removed from the patients during orthodontic treatment. We evaluated the changes that appeared on the TADs' surfaces after their use in the biological environment, depending on the morphological area in which they were inserted. In our study, we found changes in the morphology of the implant surface, and especially deposits of biological material in all study groups. On all samples examined after clinical use, regardless of the period of use, corrosion surfaces in different locations were observed. Our obtained results support the idea that the biological environment is aggressive for mini-implant structures, always producing changes to their surface during their clinical use.

正畸微型植入体临床使用后的表面分析

临时固定装置（TADs）是一种具有显著特征的正畸微型植入物，一旦植入，无需骨结合过程即可实现机械固位（主要稳定性）。然而，与生物环境的相互作用可能会导致牙科 TAD 外表面形态发生变化。在这项研究中，我们使用了由两家公司生产的 17 个铝钒钛合金 TAD，在正畸治疗期间从患者身上取下后，我们通过光学显微镜对其进行了分析。我们评估了 TAD 在生物环境中使用后其表面发生的变化，这些变化取决于插入 TAD 的形态区域。在我们的研究中，我们发现所有研究组的种植体表面形态都发生了变化，尤其是生物材料的沉积。在临床使用后检查的所有样本中，无论使用时间长短，都可以观察到不同位置的腐蚀表面。我们的研究结果支持了这样一种观点，即生物环境对微型种植体结构具有侵蚀性，在临床使用过程中总会使其表面发生变化。

期刊介绍： Journal of Functional Biomaterials (JFB, ISSN 2079-4983) is an international and interdisciplinary scientific journal that publishes regular research papers (articles), reviews and short communications about applications of materials for biomedical use. JFB covers subjects from chemistry, pharmacy, biology, physics over to engineering. The journal focuses on the preparation, performance and use of functional biomaterials in biomedical devices and their behaviour in physiological environments. Our aim is to encourage scientists to publish their results in as much detail as possible. Therefore, there is no restriction on the length of the papers. The full experimental details must be provided so that the results can be reproduced. Several topical special issues will be published. Scope: adhesion, adsorption, biocompatibility, biohybrid materials, bio-inert materials, biomaterials, biomedical devices, biomimetic materials, bone repair, cardiovascular devices, ceramics, composite materials, dental implants, dental materials, drug delivery systems, functional biopolymers, glasses, hyper branched polymers, molecularly imprinted polymers (MIPs), nanomedicine, nanoparticles, nanotechnology, natural materials, self-assembly smart materials, stimuli responsive materials, surface modification, tissue devices, tissue engineering, tissue-derived materials, urological devices.
