Titanium miniplate as anchorage to close a premolar space by means of mesial movement of the maxillary molars

Mini-implants: mechanical resource for molars uprighting

“…The placement and removal require invasive surgery, which may lead to infection. 13,18 The utilization of endosseous implants as anchorage in retromolar, 21,22 palatal and edentulous areas has been successfully described in the literature, 11,16,23,24 however they require osseointegration before the orthodontic force is applied, thus increasing the treatment time, besides the limited sites for placement.…”

“…Surgical removal of third molars was indicated to enhance the uprighting of second molars. The same procedure comprised surgical exposure and bonding of a bracket on the cusp of these teeth and placement of mini-implants (Ortoimplante Conexão, 2.0 x 9.0, medium transmucous profile) for anchorage on the retromolar region, distal and occlusal to the second molars, using a mucoperiosteal flap 11 . This site was selected to allow support for orthodontic eruption of the impacted second molars in distal and occlusal direction (Fig 7A).…”

“…Mini-implants, palatal implants and mini-plates are currently used in several clinical situations, as the treatment of open bites and uprighting of molars without adverse effects on the adjacent teeth. [11][12][13][14][15][16][17][18] Class II is the severe malocclusion most frequently found and is characterized by "distal positioning" of the mandibular teeth compared to the maxillary teeth, which may be caused by bone dysplasia or forward positioning of the alveolar process or maxillary dental arch, or even by the combination of skeletal and dental factors. 9 This case report describes the orthodontic treatment of a patient with Angle Class II malocclusion with impaction of the mandibular second molars, in which two mini-implants were used as an anchorage aid for uprighting of the teeth, which were impacted on the distal aspect of mandibular first molars.…”

Current Status of Skeletal Anchorage Dental Applications in Orthodontics, Part II

“…The orthodontic‐only (without SA) mesialization of posterior teeth is difficult, if not impossible to achieve without secondary effects on the teeth positioned anteriorly to the space . The use of SA allows for stabilization of anterior teeth while posterior teeth are being pulled mesially, as an indirect source of anchorage, or allow for direct traction of the posterior segments . It is important to note that even with SA, mesial movement of posterior segments is slow and difficult.…”

“…1 The use of SA allows for stabilization of anterior teeth while posterior teeth are being pulled mesially, as an indirect source of anchorage, or allow for direct traction of the posterior segments. [2][3][4] It is important to note that even with SA, mesial movement of posterior segments is slow and difficult. The most challenging cases involve mesialization of second molars into an old extraction site that may display bone resorption.…”
