In order to reduce time in orthodontic treatments, have been applied knowledge about bone physiology based on clinical experience and observation by H. Frost.

The injuries in bone (fractures, osteotomies or corticotomies), cause a change in metabolism. This is called regional accelerating phenomenon (RAP), where osteoclasts and osteoblasts are increased in the injured area as well as mediators and cell precursors of blood and lymph vessels.

This RAP, positively promotes the speed of orthodontic movement caused by the transient osteopenia, which is maintained by permanent orthodontic forces (Wilcko et al.).

Corticotomy also favors reducing root resorption during orthodontic treatments, based on the application of less force on the surface of the tooth structure and less damage to the pulp and improvement of stability after treatment.

The aim of this review is about the history, principles, indications, technique and the role of corticotomy in orthodontic treatment.

The method used was based on the search of information from articles published in various databases such as Pubmed, EBSCO, Hinari, Scielo.

Results and conclusions: Studies show that corticotomies help to reduce the time of orthodontic treatment and also produces fewer side effects.

Conflict of interest: None declared.
