Summary

Fixed braces (appliances) are used to straighten the malalignment of teeth. There has been a lot of research into the factors that can affect the speed of alignment of teeth but there has been very little research on how different techniques of wire attachment to the brace (ligation) can affect this.

The randomised clinical trial of 100 patients aims to compare the speed of alignment of the lower (mandibular) front teeth (incisors) using two different techniques over a period of 12 weeks. Both techniques use the conventional small elastic rings (modules) that are placed over each metal square (bracket) but they will be tied in a different configuration for each group. We will also observe any differences in the distances between the corresponding teeth either side of the lower jaw for each group and the bracket failure rates.
