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.

Interdisciplinary Treatment of Gingival Recession
Volume 50 : Number 2 : Page 0 : Feb 2016
Gingival recession may be localized or generalized, but always involves at least one tooth surface. It occurs more often in the mandibular arch than in the maxillary arch. Gingival displacement can become a critical complication, leading to esthetic complaints, root sensitivity, loss of periodontal attachment, difficulty in performing oral hygiene, and increased risk of root caries. Exposed root surfaces are also more prone to abrasion from brushing.

Treatment of Anterior Open Bite with a Mini-Implant-Supported Tongue Crib
Volume 51 : Number 1 : Page 0 : Jan 2017
Anterior open bite is attributable to a combination of skeletal, dental, soft-tissue, and habitual factors. Retained infantile swallowing and tongue-thrust habits are the main causes, but other possibilities include unfavorable growth, heredity, pacifiers and digital habits, enlarged lymphatic tissue, and improper tongue function and posture. Treatment strategies aimed at these different etiologies include behavior modification, orthodontic correction alone, and various combinations of orthodontic and orthopedic or orthodontic and surgical correction.

The Zygoma and the Symphysis: New Extra-Alveolar Sites for Long Mini-Implants
Volume 51 : Number 10 : Page 680 : Oct 2017
Long mini-implants placed in extra-alveolar areas of good bone quality and quantity can provide stable anchorage without the added cost and surgery of miniplates. The authors evaluate the potential of two new sites, the zygoma and the symphysis, in orthopedic Class III treatment.
