The skeletal cortical anchorage using titanium microscrew implants

Abstract

Anchorage plays an important role in orthodontic treatment. Endosseous implants may be considered adequate firm anchorage. However, chinicians have hesitated to use endosseous implants as orthodontic anchorage because of limited implantation space, high cost, and long waiting period before osseointegration occurs. Recently, some clinicains have tried to use titanium miniscrews and microscrews in treatment due to their many advantages such as ease of insertion and removal, low cost, immediate loading, and the ability to place microscrews in any area of alveolar bone. The author treated a case with skeletal cortical anchorage using titanium microscrew implants. During six months of orthodontic force application from skeletal cortical anchorage, the author could get 4mm bodily retraction and intrusion of upper anterior teeth. The most outstanding result was a 1.5mm posterior retraction of the upper posterior teeth. The titanium microscrew implants and remained firm and stabel throughout treatment. These results indicate that skeletal cortical anchorage might be a very good option.
