Corticotomy Facilitated Orthodontic Treatment In Adults : A Report Of Two Cases, Randall E. Hoff

Loma Linda University Electronic Theses, Dissertations & Projects

The corticotomy procedure is a surgical technique that has been used to facilitate orthodontic treatment for many years. Proponents of this technique contend that occlusal results are more stable and treatment time is reduced. In this study, two cases of dento-alveolar abnormality are presented that were successfully treated in a relatively short time by using the combined efforts of the surgeon and the orthodontist. Although corticotomy has limited applications, it has a place in the armamentarium of the modern orthodontist.
