文献中已经提出了几种策略来加速牙齿移动,其中许多是侵入性的,有许多副作用,如手术技术(皮质切开术和压电切开术)。这项研究调查了透热疗法在多大程度上可以加速正畸对准阶段。
选择具有相同大小的下牙齿拥挤指数的患者。在下弓进行了镍钛(NiTi)热弧0.015的正畸治疗,与每周使用口内手机进行透热疗法有关。治疗的总持续时间为三周。在每次会议期间,采用口内换能器刺激左半牙弓的硬组织和软组织,它也像右边的一样正畸对齐。
比较两个半身世纪的四个元素的牙齿运动,人们发现,总的来说,与未治疗侧相比,在治疗侧检查的两颗牙齿发生了更多的变化,虽然不是很大的数量。
使用透热疗法,根据作者的说法,是一种非侵入性方法,可以加快正畸对齐阶段并减少治疗持续时间,从而降低龋齿的风险,牙龈衰退,根吸收,和患者依从性的改善,没有副作用。需要进一步的研究和足够的样本量来确认发现。
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.
