Feasibilities toward accelerated orthodontic tooth movement

Accelerated orthodontic tooth movement remains one of the difficult and unsolved tasks in orthodontics. Experimentally and clinically, several approaches have been advocated toward accelerated orthodontic tooth movement through physiology/ biology, such as injection of cytokines, hormones, induction of osteopenia, surgical acceleration; or through biomechanics, such as application of self-ligation brackets. No matter what the approach is, the facts are the rate of orthodontic tooth movement in younger patients is faster than in adult patients, and there are individual variations among patients. In this presentation, the advocated approaches will be discussed, and the detection of individual variation and future feasibilities toward accelerated orthodontic tooth movement will be addressed.

Miniscrews for orthodontics: From evidence-based histological, clinical, and biomechanical perspective

Recently, miniscrews utilized as an orthodontic anchorage has become widely accepted among orthodontists. In our department of Orthodontics in Okayama University hospital, we have been using various types of miniscrews since 1997. Thus, we have been able to obtain enormous clinical and basic data with regard to the miniscrew study. I would like to discuss the following issues of miniscrews used as anchorage in orthodontic treatment from “evidence-based” perspective.
1) Histological aspects and histomorphometric analysis of alveolar bone surrounding miniscrews
2) Clinical aspects in the use of miniscrews: where and what type of miniscrews are suitable?
3) Biomechanical consideration during the use of miniscrews
4) Comparison between conventional orthodontics: diagnosis, treatment planning, and treatment outcome
