n a crisp, snowy, Saturday morning in Saint Louis, I stopped for a few minutes to watch a team of hockey players practicing in the park across the street from my hotel. I had spent several weeks preparing for a meeting of the Council on Scientific Affairs (COSA), led by Tom Southard, chair of the orthodontic department at the University of Iowa. His agenda was lengthy, but the primary task was to select the winners of the Milo Hellman, Harry Sicher, and Thomas M. Graber research awards. As I awaited arrival of the entire committee, I could not help but appreciate what a similar AAO committee had experienced some 42 years ago, when my own research entry was considered for the Milo Hellman Research Award. This year’s COSA had an excellent group of papers to consider. The subject areas included in vivo gene transfer, implant stability, root resorption, TMD alterations, 3-D cone-beam imaging, distraction osteogenesis, growth prediction, and orthodontic materials. The Milo Hellman Research Award is presented to the top paper of unusual merit and carries a cash award $3000, in addition to up to $750 in travel and lodging expenses. The 2005 winner is Courtney A. Dunn, DDS, MS, University of Michigan, for “Tissue engineering of alveolar bone adjacent to dental implants through gene therapy.” The study demonstrates that adenovirus delivered in a collagen matrix is capable of the targeted and sustained release of a transgene for up to 35 days at dental implant osteotomy sites. In vivo gene therapy of BMP-7 initiated bone formation successfully in bony defects surrounding oral implants. This type of gene therapy offers potential for alveolar bone engineering applications. The Harry Sicher First Research Essay Award recognizes a meritorious first research effort. The essays are generally based on masters’ degree theses prepared as part of a graduate orthodontic educational program. Each orthodontic department in the United States and Canada is invited to submit suitable research papers. In addition, anyone who has not previously published research in orthodontics or related fields may submit an original paper Am J Orthod Dentofacial Orthop 2005;127:273 0889-5406/$30.00 Copyright © 2005 by the American Association of Orthodontists. doi:10.1016/j.ajodo.2005.01.005
not prepared under the auspices of a graduate teaching program. The author of the top entry receives $2000 plus up to $750 for travel and lodging expenses. This year’s winner is Scott A. MacGregor, DDS, MSc, FRCD(c), University of Toronto, for “The effect of micro-implant surface geometry on peri-implant bone adaptation under orthodontic loading in the rabbit tibia.” In part 1 of this study, the stability and peri-implant adaptation of loaded and unloaded machined threaded micro-implants were examined. In part 2, the characteristics of loaded and unloaded porous-surfaced microimplants were compared. The porous-surfaced microimplants had significantly greater peri-implant bone response than the corresponding control implant surfaces. The porous-surfaced micro-implants also showed the most bone formation at their bone-to-implant interface. COSA gave 4 special merit awards this year, designated as the Thomas M. Graber Awards of Special Merit. These awards recognize excellence in research in both clinical and basic science categories. The 2005 winners are Kristy Chung, DDS, University of California, San Francisco, for “The role of female reproductive hormones in the etiopathogenesis of TMJ diseases in women”; Debora Alvares Harris, BDS, University of Sydney, Australia, for “Volumetric analysis of root resorption craters after application of controlled intrusive light and heavy orthodontic forces: A micro CT scan study” (she was to receive her MDSc in 2004); Shiva Shadmand, DDS, MSc, PhD, University of Toronto, for “Mandibular deficiency in knockout mice lacking bone sialoprotein expression”; and Paul Rim, DDS, University of California, San Francisco, for “Characterization of the time-dependent differentiation of calvaria-derived rat mesenchymal stem cells in three-dimensional agarose gels.” This group of awards carries a $1200 honorarium with up to $750 for travel and lodging expenses. All recipients must present their papers during the 105th Annual Session of the American Association of Orthodontists, May 20-24, 2005, and all manuscripts will be published in the AJO-DO. Take a minute to congratulate these successful students now, and then listen to them in San Francisco. 273
