Vol. 14 – Number 53 – 2021 Case report Page 62-69 Complication in the buccal shelf miniscrew installation – case report Pedro César Fernandes dos Santos1 Lorena Walesca Macedo Rodrigues2 Aline Levi Baratta Monteiro2 Pedro Diniz Rebouças3 Benedito Viana Freitas4 Marcelo Cerqueira Trévia5 Abstract The use of dental support as orthodontic anchorage, used in conventional corrective orthodontic treatment, may interfere in the proper functioning of the applied mechanics, because the teeth that are used as support may suffer displacement. Nowadays, the use of miniimplants, among them buccal-shelf, has been increasingly used, as they reduce the chances of possible side effects resulting from the mechanics, because the support ceases to be dental and becomes skeletal. Despite low failure rate, according to the literature, difficulty of access and individual determination of the best area of installation of this type of miniscrew should be thoroughly evaluated, in addition to verification of bone conditions, thus avoiding the risk of poor insertion. This article presents a case of installation of an extra-alveolar miniscrew buccal-shelf type in which the device ended up being inserted in an inadequate trajectory, causing an acute inflammatory process. After removal of the extra-alveolar mini-screw, a new installation was performed guided by cone-beam computed tomography, and the orthodontic treatment was successfully concluded.
