Mandibular Arch Retraction with Retromolar Skeletal Anchorage in a Class III Open-Bite Patient

DR. SACHIN AGARWAL , BDS, MDS | DR. NEELESH SHAH , BDS, MDS | DR. SUMIT YADAV , BDS, MDS, PhD | DR. RAVINDRA NANDA , BDS, MDS, PhD

Volume 48 : Number 12 : Page 775 : Dec 2014

The retromolar area has been recommended for mini-implant placement because of its thick cortical bone and lack of vital structures.1-3 Skeletal anchorage from this region allows teeth to be moved ove...

Space Regaining with Modified Palatal Anchorage Plates

DR. YOON-AH KOOK , DDS, PhD | DR. JAE HYUN PARK , DMD, MSD, MS, PhD | DR. MOHAMED BAYOME , BDS, MMS, PhD

Volume 49 : Number 9 : Page 0 : Sep 2015

Space regaining is an important treatment modality for eruption guidance. Shalish and colleagues reported that space regaining and the removal of obstructions can facilitate spontaneous eruption of impacted premolars. Although several devices have been developed to regain space through molar distalization, these methods may result in anchorage loss, incisor proclination, and a slight increase in vertical facial dimension. Koutzoglou and Kostaki reported a relationship between rapid palatal expansion and the natural eruption of impacted canines, but maxillary expansion has also been related to a loss of height and thickness of buccal alveolar bone at the anchorage teeth.

Lower-Molar Distalization with Mini-Implant Anchorage in Asymmetrical Class II Cases

DR. FABRICIO PINELLI VALARELLI , DDS, MSc, PhD | DR. MANOEL HEITOR BRITO , DDS, MSc | DR. RODRIGO HERMONT CANÇADO , DDS, MSc, PhD | DR. KARINA MARIA SALVATORE FREITAS , DDS, MSc, PhD

Volume 51 : Number 2 : Page 0 : Feb 2017

About half of all Class II malocclusions are asymmetrical. If the upper molar is mesially displaced, the maxillary midline will deviate toward the Class I side, and treatment will require either extraction of one upper premolar or distal molar movement on the Class II side. In 61% of asymmetrical Class II cases, however, where the lower molar is distally displaced, the maxillary midline will match the medium sagittal plane, but the mandibular midline will deviate toward the Class II side. If the profile is convex, asymmetrical extractions (two upper premolars and one lower premolar on the Class I side) are generally used for correction. Another option is to extract four premolars, but this will extend treatment time.

Intrusion of Maxillary Posterior Teeth to Correct a Severe Anterior Open Bite

DR. BILAL AL-FALAHI , BDS, MDS | DR. AHMAD MOHAMMAD HAFEZ , DDS, MDS, PhD | DR. MAHER FOUDA , DDS, MDS

Volume 51 : Number 6 : Page 326 : Jun 2017

This clinical study was designed to evaluate the effects of a simple appliance for intrusion of upper posterior teeth in non-growing patients with severe anterior open bite, using miniscrew anchorage. Cone-beam computed tomography was used for pre- and post-intrusion measurements of 15 subjects. Two representative cases are shown.

A Simple Glue-Tray Guide for Precise Miniscrew Insertion

DR. SARABJEET SINGH , BDS, MDS | DR. MANU RASHMI SHARMA , BDS, MDS | DR. NAVREET SANDHU , BDS, MDS | DR. ARUNA RANAUT , BDS

Volume 51 : Number 6 : Page 361 : Jun 2017

This Pearl demonstrates a guide for more accurate insertion of miniscrews, using a transfer tray made from glue as described in an indirect-bonding technique. The simple glue tray provides three-dimensional orientation and stabilizes the manual driver during placement, with the precise location of the miniscrew confirmed by a periapical radiograph.
