Corticotomy is a minor surgical procedure used to facilitate & accelerate tooth movement in certain cases where conventional orthodontics find its limitation. A very few published case reports of corticotomy facilitated orthodontics are present till date to substantiate its scope. Here is case report of a patient who reported to the Department of Orthodontic & Dentofacial Orthopedics after being rejected during her medical examination for armed force service on account of having bilateral posterior crossbite . She was given 60 days for the correction of this malocclusion before she could reappear for the examination . Considering the age for rapid maxillary expansion & limited time circumstance so corticotomy facilitated orthodontic was indicated in this case & also hyrax followed AMEX (asymmetrical maxillary expansion appliance ) was required to correct the crossbite.
