fa Effect of piezopuncture on tooth movement and bone remodeling in dogs ارتودنسی Orthodontics پژوهشي Research <p> <strong>Introduction</strong></p><p>  The aim of the study was to elucidate whether a newly developed, minimally invasive procedure, piezopuncture, would be a logical modification for accelerating tooth movement in the maxilla and the mandible. </p><p> <strong>Methods</strong></p><p>  Ten beagle dogs were divided into 2 groups. Traditional orthodontic tooth movement was performed in the control group. In the experimental group, a piezotome was used to make cortical punctures penetrating the gingiva around the moving tooth. Measurements were made in weeks 1 through 6. Tooth movement and bone apposition rates from the histomorphometric analyses were evaluated by independent t tests. </p><p> <strong>Results</strong></p><p>  The cumulative tooth movement distance was greater in the piezopuncture group than in the control group: 3.26-fold in the maxilla and 2.45-fold in the mandible. Piezopuncture significantly accelerated the tooth movements at all observation times, and the acceleration was greatest during the first 2 weeks for the maxilla and the second week for the mandible. Anabolic activity was also increased by piezopuncture: 2.55-fold in the maxilla and 2.35-fold in the mandible. </p><p> <strong>Conclusions</strong></p><p>  Based on the different effects of piezopuncture on the maxilla and the mandible, the results of a clinical trial of piezopuncture with optimized protocols might give orthodontists a therapeutic benefit for reducing treatment duration. </p><hr><p></p><p> <strong>Source: </strong>American Journal of Orthodontics & Dentofacial Orthopedics </p><p> <a href="http://www.ajodo.org/article/S0889-5406(13)00264-3/abstract" target="_blank"><font color="#0000ff">Full Text</font></a></p> 0 0 http://idai.ir/browse.php?a_code=A-10-32-1812&slc_lang=fa&sid=1 Young-Seok Kim 10031947532846008526 10031947532846008526 No School of Dentistry, Kyung Hee University, Seoul, Korea Su-Jung Kim 10031947532846008527 10031947532846008527 No Department of Orthodontics, School of Dentistry, Kyung Hee University, Seoul, Korea Hyun-Joo Yoon 10031947532846008528 10031947532846008528 No School of Dentistry, Kyung Hee University, Seoul, Korea Peter Joohak Lee 10031947532846008529 10031947532846008529 No Section of Orthodontics, School of Dentistry, University of California at Los Angeles, Calif Won Moon 10031947532846008530 10031947532846008530 No Section of Orthodontics, School of Dentistry, University of California at Los Angeles, Calif Young-Guk Park 10031947532846008531 10031947532846008531 Yes Department of Orthodontics, School of Dentistry, Kyung Hee University, Seoul, Korea
