THE EDITOR'S CORNERThe Challenge of Bimaxillary ProtrusionROBERT G. KEIM DDS, EdD, PhDThe condition of bimaxillary protrusion—characterized by proclined and protrusive upper and lower incisors and a tendency toward a hyperdivergent facial pattern—was recognized early in the profession ... |

Hybrid Hyrax Distalizer and Mentoplate for Rapid Palatal Expansion, Class III Treatment, and Upper Molar DistalizationTHANH-HA CLARENBACH DMD, BENEDICT WILMES DMD, MSD, PhD, BENJAMIN IHSSEN DMD, SIVABALAN VASUDAVAN BDSc, MDSc, MPH, DIETER DRESCHER DMD, PhDIn a preadolescent Class III patient, the use of a surgically placed Mentoplate in the anterior mandible facilitates a transfer of protractive forces to the underlying bone structure without the need for extraoral elastics. At the same time, the skeletally anchored Hybrid Hyrax Distalizer provides rapid palatal expansion along with upper-molar distalization. |

Intrusion of Maxillary Posterior Teeth to Correct a Severe Anterior Open BiteBILAL AL-FALAHI BDS, MDS, AHMAD MOHAMMAD HAFEZ DDS, MDS, PhD, MAHER FOUDA DDS, MDSThis 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. |

Step-By-Step Traction of a Palatally Impacted CanineCHENG-QIONG PAN BDS, MDS, YAN GU BDS, MDS, JUN-QING MA BDS, MDS, PhD, CHUN-YANG ZHAO BDSTwo-phase treatment of a mixed-dentition patient with a palatally impacted canine is described and illustrated. After surgical exposure of the canine, the authors perform distal traction with miniscrew anchorage to relieve the obstruction caused by the adjacent lateral incisor. Under the guidance of cone-beam computed tomography, the canine is then moved into appropriate position for forced eruption into the arch. |

Forsus Appliance for Treatment of Class II, Division 2 Malocclusion in AdultsHARSHAL ASHOK PATIL BDS, MDS, VEERENDRA V. KERUDI BDS, MDS, NEERAJ S. PATIL BDS, MDS, JITENDRA S. SHARAN BDS, MDS, PhD, PAWANKUMAR DNYANDEO TEKALE BDS, MDSTreatment of a Class II, division 2 patient with no growth remaining has traditionally involved either orthognathic surgery or an orthodontic compromise requiring extraction of the upper first premolars. The authors present a third approach for consideration in borderline cases: nonextraction treatment using the Forsus Fatigue Resistant Device, a fixed-functional appliance. |

CASE REPORTCorrection of Bimaxillary Protrusion after Extraction of Hopeless Mandibular Posterior Teeth and Molar ProtractionUN-BONG BAIK DDS, MS, PhD, JAE HYUN PARK DMD, MSD, MS, PhD, YOON-AH KOOK DDS, PhDThis case of an adult patient with bimaxillary protrusion is complicated by the need to extract posterior teeth due to extensive caries. Skeletally anchored molar protraction allows asymmetrical mechanics to be used for extraction space closure, making the authors’ technique a potential alternative to prosthetic restoration of the edentulous areas. |

PEARLSA Simple Glue-Tray Guide for Precise Miniscrew InsertionSARABJEET SINGH BDS, MDS, MANU RASHMI SHARMA BDS, MDS, NAVREET SANDHU BDS, MDS, ARUNA RANAUT BDSThis 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. |

Two-phase treatment of a mixed-dentition patient with a palatally impacted canine is described and illustrated. After surgical exposure of the canine, the authors perform distal traction with miniscrew anchorage to relieve the obstruction caused by the adjacent lateral incisor. Under the guidance of cone-beam computed tomography, the canine is then moved into appropriate position for forced eruption into the arch.
