  • Title: The role of alveolar corticotomies in orthodontic anchorage management.
    Author: Echchadi Mel M.
    Journal: Int Orthod; 2014 Jun; 12(2):171-87. PubMed ID: 24813102.
    Abstract:
    The aim of this article is to describe our therapeutic approach in the management of Class III malocclusions requiring repositioning of the anterior-inferior segment. This approach is based on the reasoned use of selective alveolar corticotomies in anchorage management. The patient was a 17-year-old young woman presenting severe antero-inferior crowding, a Class III malocclusion and residual spaces in the upper arch. Orthodontic treatment consisted of extraction of the mandibular 1st premolars and maximum anchorage. A local mandibular corticotomy was performed prior to orthodontic treatment from the distal aspect of the right canine to the distal surface of the left canine, sparing the premolar segments. The maxillary arch received no corticotomy and was treated by conventional orthodontic techniques. En masse retraction of the 6 antero-inferior teeth was done using sliding mechanics. Active treatment was completed in 8 months. The corrections are still stable 2 years post-retention.
