The aim of this narrative review is to discuss on different approaches of the flapless corticotomy techniques to ac- celerate orthodontic tooth movement. There was limited understanding about the effect of the surgical procedures because of the great variations in the procedures between the flapless corticotomy techniques. Hence, no specific technique can be claimed to be superior to another. Eleven clinical trials have been reviewed from PubMed, Science Direct, and Google Scholar using the keywords such as accelerated, orthodontic tooth movement (OTM), minimally invasive corticotomy, RAP, corticision, piezocision, lasercision/laser assisted flapless corticotomy (LAFC), micro-os- teoperforations (MOPs), discision and their combinations in the last 10 years. Early reports showed that Piezocision, MOPs and LAFC procedures are comparatively less aggressive flapless corticotomy procedure to accelerate OTM and more comfortable to the patient.
