The usual rate of tooth movement by conventional protocols of mechanotherapy signifies approximately 1 mm/month. The representative noxious complication over time involves the decay of compliance from the patients and consequent fatigue of the orthodontists.
A surgically induced transient osteopenia (RAP; regional acceleratory phenomenon) is perpetuated by tooth movement at the rate of 1 mm/week. The osteopenic milieu is clinically expedient with sound biologic foundation, and renders the orthodontic outcome more stable and less prone to complications.
Orthodontic tooth movement results from forces applied to tooth, that evoke cellular responses in the teeth and their surrounding tissues, including the periodontal ligament (PDL), alveolar bone, and gingiva. It is advantageous for the orthodontist to know the details of the biological events that unfold during tooth movement, because some of these details may differ from one remedy to another, due to variables such as gender, age, psychological status, nutritional habits, and drug consumption. The purpose of this presentation is, therefore, to emphasize the fact that orthodontics is a field of endeavor where mechanics and biology are integrated, and to stress the reality that tooth movement is conducted in individual human beings, each composed of a unique and intricate physiological system. Biological variations may be the foundation of the differences that are frequently observed in the outcomes of orthodontic treatment between patients with similar malocclusions, treated with different regimen.
This presentation will present evidence that minor surgical procedure by orthodontist oneself can receive accelerated rates of tooth movement with impunity. It will introduce the novel way to orthodontics as a system that enhances the rate of bony and periodontal response, thereby shortening the duration of treatment, and preventing long-lasting tissue damage.
