Distal Movement of Lower Molars with Miniplate Anchorage
Volume 49 : Number 10 : Page 0 : Oct 2015
The permanent teeth most likely to become impacted are the upper and lower third molars and the upper canines, followed by the lower premolars. Impaction of lower first permanent molars is rare, with an estimated prevalence of .01%. Treatment options include extraction, with or without osseointegrated implant placement, dental luxation, or orthodontic loading; orthodontic treatment with intra- or extraoral devices; and orthodontic extrusion with screws or plates as temporary skeletal anchorage. Because normal eruption of the lower first and second molars is essential for development and coordination of the dental arches and the facial skeleton, a conservative treatment plan aimed at proper positioning of these teeth in the mandibular arch should be considered whenever possible.

The Indirect Palatal Miniscrew Anchorage and Distalization Appliance
Volume 50 : Number 2 : Page 0 : Feb 2016
Distalization of the upper molars is an important treatment option for the correction of Class II malocclusion. Although extra- or intraoral devices have traditionally been used in such cases, the esthetic and social concerns associated with headgear and the undesirable anchorage loss caused by intraoral devices have prompted clinicians to investigate the possibility of using miniscrew implants as anchorage devices. Most of the miniscrew-supported intraoral appliances used to distalize the upper molars are adaptations of preexisting non-compliance devices, such as the Distal Jet or Pendulum, anchored to miniscrews in the paramedian palate or midpalatal suture. Although these appliances are capable of producing significant distal molar movement, they are difficult to fabricate and, when palatal acrylic buttons are used, tend to impede oral hygiene.
