Horizontal tooth displacement Lack of space is one of the main reasons for the oblique positioning of teeth. One way to solve this prob- lem is to create the necessary space. Conversely, premature loss of teeth or anatomical abnormali- ties may result in gaps that require modification for various reasons. For the correction of horizontal tooth displacement, miniscrews can be used as these produce no unde- sirable reactive effects. Distalization The first case (Figs. 1a–c) presented involves a frequent- ly encountered problem: the patient’s molars had migrated in a mesial direction. This resulted in a marked loss of space in the region of the canines. The two treatment options in such a case are extraction or dis- talization. In this case, distalization PRSRTSTD U.S.Postage PAID Permit#306 Mechanicsburg,PA Miniscrews: a focal point in practice uPage 18 Calling all residents How to get Wired For Success next year uPage 21 All about education New clinics change the way practices operate uPage 10 Opportunity awaits Tips for landing the perfect associate job DentalTribuneAmerica 213West35thStreet Suite#801 NewYork,NY10001 June & July 2010 www.ortho-tribune.com Vol. 5, nos. 6 & 7 ORTHO TRIBUNE The World’s Orthodontic Newspaper · U.S. Edition g OT page 4 Michigan bound By Kristine Colker, Managing Editor T he 22nd annual Graduate Orth- odontic Residents Program (GORP) is heading back to the University of Michigan in Ann Arbor. From Aug. 6–8, orthodontic resi- dents from across the United States and Canada will gather together to attend the yearly event. More than 400 students are expected to attend this year’s meet- ing, which will feature three days of sessions from such speakers as Dr. James A. McNamara, Dr. Vincent G. Kokich and Dr. John Graham, employed. Such negative results can be avoided by the use of miniscrews Miniscrews can be inserted in the vestibular and — as in this example — palatinal areas. Vestibular inser- tion of a miniscrew (e.g., between the premolars) is always associated with the miniscrew’s eventual inter- ference with tooth migration. When this occurs, the miniscrew must be extracted and a conventional form was a viable option and extraction was unnecessary. Conventional techniques for dis- talization (apart from the use of headgear) require support from other groups of teeth. Creating anchorage in this way has negative reactive effects. In the example under consider- ation, it is highly probable that pro- trusion of the anterior teeth would have resulted should a conventional method for distalization have been SPECIALGORP EDITION AD Part 2 of 6: Clinical examples Fig. 1a: Distalization of the upper molars.
