Evaluation of en-masse retraction using microimplant versus conventional techniques: An in vitro study
Main Article Content
Abstract
Results: The rate of space closure showed no significant difference among the three groups (p?0.05), while results regarding type of tooth movement showed a significant difference among the three groups (p?0.05), where group 3(0.59±0.09) showed a more degree of controlled tipping than group1(0.33±0.19) while group 2(-0.50±0.09) showed an uncontrolled tipping movement.
Conclusions: It is concluded that microimplant anchored sliding mechanics gives better control over the en masse retraction mechanics and greater retraction. Conventional techniques result in extrusion and move the teeth in less degree of translation movement.

Some publishers allow free and unrestricted re-use of article content they own, such as under the CC BY license. Other publishers use licenses that allow re-use only if the same license is applied by the person or publisher re-using the content. If the paper was published under a CC BY license or another license that allows free and unrestricted use, you may use the content in your JBCD paper provided that you give proper attribution, as explained above.If the content was published under a more restrictive license, you must ascertain what rights you have under that license. At a minimum, review the license to make sure you can use the content. Contact that JBCD if you have any questions about the license. If the license does not permit you to use the content in a paper that will be covered by an unrestricted license, you must obtain written permission from the publisher to use the content in your JBCD paper. Please do not include any content in your JBCD paper which you do not have rights to use, and always give proper attribution.
# If any relevant accompanying data is submitted to repositories with stated licensing policies, the policies should not be more restrictive than CC BY.
