Abstract

Lecture: Why we should NOT accelerate orthodontic tooth movement

Over the past two decades, numerous surgical and non-surgical techniques have been proposed to accelerate orthodontic tooth movement. However, none have provided a moderate level of evidence supporting their clinical effectiveness. Although some studies have reported transient positive effects during specific phases of orthodontic treatment, these findings have not been consistently validated across the entire treatment duration, nor have they adequately addressed potential complications or the risk of relapse.

From a biological standpoint, is it scientifically justifiable to pursue accelerated tooth movement? Does an increase in the rate of tooth displacement necessarily translate into improved treatment outcomes? What ethical considerations should be taken into account. Perhaps it is time to redirect our focus toward aspects that enhance patient well-being and advance the standards of our profession. I look forward to exchanging thoughts on these aspects with you and drawing inspiration from our shared insights.
