   Miniscrew implants provide an excellent orthodontic anchorage. Besides the clinical benefits, miniscrew implants cause minor discomforts and in certain instances poses problematic complications. Damage to the adjacent tooth structure is the most feared complication of miniscrew implant placement, while fracture of miniscrew implants is the rarest.

   1 de mar. de 2006 · Numerous anatomical sites for miniscrew application have been presented.5–7 Kanomi8 and Costa et al9 implanted microscrews (1.2 mm in diameter) and miniscrews (2.0 mm in diameter) into the basal bone below the roots of the teeth to prevent root damage. Because the implanted microscrews were positioned so high, the applied force for applying vertical vectors was limited.

   Objective: To investigate the fracture resistance of six commonly used self-drilling orthodontic mini-implants by comparing their respective fracture torques during insertion. Materials and methods: Ninety self-drilling mini-implants from six manufacturers (Aarhus, Dual-Top, OrthoEasy, Tomas-pin, Unitek, and VectorTAS), with diameters ranging from 1.4 to 1.8 mm, were inserted into acrylic ...

   24 de sept. de 2018 · Orthodontic miniscrew implants provide acceptable success rates that vary among the explored insertion sites. Low quality of evidence suggests that miniscrew implants inserted in palatal locations exhibit a failure rate of 1.3, 4.8 and 5.5% for the midpalatal, paramedian and parapalatal locations respectively.

   23 de abr. de 2015 · To avoid fracture, the MSI’s material should have adequate strength to resist insertion torque. Alternatively, instead of Ti, 316 ... it is difficult to have 3–4 histologic slides from an orthodontic miniscrew less than 2mm in diameter. 3D analysis seems to be a useful alternative approach to estimate secondary stability ...

   Miniscrew dimensions must be selected according to the desired insertion site, considering that smaller screw diameters present a higher risk of fracture during placement. Although insertion into attached gingiva is preferable, the thickness of the tissue must not be excessive; at least half the

   20 de sept. de 2022 · Miniscrew stability and soft tissue condition were then closely examined at each appointment. TADs were considered long-term stable if they served as an anchorage until completion of distalization of the mandibular teeth. During the follow-up visits (every 4–6 weeks), miniscrew stability and condition of the surrounding soft tissue were ...
