“…Radiography has been reported to be a good tool to assess signs of screw damage to dental root structure, but the true extent of the damage can only be reliably ascertained histologically. 20,21 Screw-induced dental trauma is associated with infection or inflammation and can result in fixation failure and tooth loss 9,19,35 ; therefore, it is imperative to minimize screw-root involvement during application of miniplates to the mandible. In human patients, titanium miniscrews can cause damage to the inferior alveolar nerve, which in most cases results in transient paresthesia or dysesthesia.…”

“…tooth root or mandibular canal abnormalities indicative of iatrogenic damage caused by the fixation construct. [19][20][21] Iatrogenic damage to tooth roots or the mandibular canal by screws was quantified by counting the number of screw holes that were superimposed over a tooth root 20 or the mandibular canal, a method that has high sensitivity (low falsenegative rate) and low specificity (high false-positive rate).…”

“…[8][9][10] Moreover, contact with the root of a tooth can lead to mobility and ultimately failure of the mini implant. Orthodontic literature reports 0.47% to 43.3% of root perforation in patients associated with mini implant placement.…”

“…De acordo com Kuroda et al (2007), Asscherickx et al (2008) e Shinohara et al (2013), o contato radicular parece ser um dos principais fatores de risco que levam à falha de um mini-implante, além das sequelas deixadas. Quando a extensão do contato entre a raiz dentária e o mini-implante é pequena, as lesões ocasionadas não parecem ser permanentes, uma vez que se observa reparação do cemento e ligamento periodontal (ALVES et al, 2013), tanto em animais (ASSCHERICKX et al, 2005;BRISCENO et al, 2009;DAO et al, 2009;HEMBREE et al, 2009;KIM, 2011;RENJEN et al, 2009), como em humanos (AHMED et al, 2012;KADIOGLU et al, 2008;MAINO et al, 2007). Porém, nos contatos mais extensos e na presença de perfuração radicular pelo mini-implante, podem ocorrer danos mais severos ao ligamento periodontal e às estruturas radiculares como fraturas, trincas, reabsorções radiculares e anquilose (LEE et al, 2010).…”

“…A avaliação do contato/perfuração radicular por mini-implantes geralmente tem sido feita através de análise histológica (AHMED et al, 2012;ASSCHERICKX et al, 2005;BRISCENO et al, 2009;SHIN;KYUNG, 2008;DAO et al, 2009;KIM, 2011;LEE et al, 2010;MAINO et al, 2007;RENJEN et al, 2009) TASDEMIR, 2011;HWANG, 2011;KURODA et al, 2007;MCCABE;KAVANAGH, 2012), muitas vezes limitadas por ser tratar de imagens bidimensionais (ASSCHERICKX et al, 2008), e por tomografia computadorizada de feixe cônico (KURODA et al, 2007;SHIGEEDA, 2014;SHINOHARA et al, 2013;SON et al, 2014;WATANABE et al, 2013) (BARROS et al, 2011;FLORVAAG et al, 2010;HWANG, 2008;WILMES et al, 2008a;DRESCHER, 2008). Quando a colocação dos mini-implantes é realizada sem perfuração prévia, exige-se mais força de torção para inserção SHIN;KYUNG, 2008;MASSIF;FRAPIER;MICALLEF, 2007;MISCHKOWSKI et al, 2008 Ainda na tabela 4, observa-se que não houve uma relação direta entre o aumento do diâmetro dos mini-implantes com o aumento do torque de inserção, relação esta tão frequente na literatura (BARROS et al, 2011;FLORVAAG et al, 2010;HWANG, 2008;WILMES et al, 2008a;…”
