Several strategies have been proposed in the literature to accelerate tooth movement, many of which are invasive and have numerous side effects, such as surgical techniques (corticotomy and piezocision technique). This research investigates to what extent diathermy can accelerate the orthodontic alignment phase.
A patient with lower teeth crowding index of the same magnitude was selected. The orthodontic treatment with Nickel-Titanium (NiTi) thermal arc 0.015 in the lower arch was performed, associated with a weekly application of diathermy using the intraoral handpiece. The total duration of treatment was three weeks. During each session, an intraoral transducer was employed to stimulate the hard and soft tissues of the left dental hemiarch, which was also orthodontically aligned like the right one.
Comparing the tooth movements of four elements of the two hemiarchies, it was found that, overall, the two teeth examined on the treated side underwent a more significant number of changes than on the untreated side, although not by a significant amount.
The use of diathermy, according to the authors, is a non-invasive approach that may speed up the orthodontic alignment phase and reduce treatment duration, resulting in a lower risk of caries, gingival recessions, root resorptions, and patient compliance improvement, without side effects. Further studies and an adequate sample size will be needed to confirm the findings.
文献中提出了几种加速牙齿移动的策略,其中许多策略都是有创的,并且有许多副作用,如手术技术(皮质切开术和压电切割技术)。本研究旨在探讨透热疗法在多大程度上可以加速正畸排齐阶段。
选择了一名具有相同程度下颌牙齿拥挤指数的患者。使用镍钛(NiTi)热弓丝 0.015 在下颌弓进行正畸治疗,并每周使用口腔内手柄进行透热治疗。治疗总时长为三周。在每次治疗中,使用口腔内换能器刺激左侧牙弓的硬组织和软组织,同时对右侧牙弓进行正畸对齐。
比较两个半弓的四个元素的牙齿移动情况,发现总的来说,治疗侧的两个牙齿比未治疗侧经历了更多的变化,尽管差异并不显著。
作者认为,透热疗法是一种非侵入性的方法,可以加速正畸排齐阶段,缩短治疗时间,降低龋齿、牙龈退缩、牙根吸收和患者依从性改善的风险,同时没有副作用。需要进一步的研究和足够的样本量来证实这些发现。
