Clinical Trial Summary

The purpose of this study is to compare the Full Fixed Preadjusted appliances (regular braces) when to the BRIUS system.

Description:

This is a randomized controlled trial which aims to identify the effectiveness of alignment in the BRIUS group when compared to the full fixed appliance group.

The secondary aim of the study is to identify any difference in discomfort experienced by the patients when undergoing treatment using the two appliances

The investigators also aim to quantify the extent of tooth movement that is achieved through each appliance within a given time frame

Intervention

Device:
• BRIUS
This is a device that is designed based on movements planned virtually on a computer program. Then all the planned movements are embedded into the wire causing the wire to have the necessary bends to move every tooth into its pre-planned final position. This causes the pre-activated wire to consistently express a low force over a long period of time onto all the teeth. This allows the teeth to move into the final position and treatment progresses towards completion

Outcome

Type	Measure	Description	Time frame	Safety issue
Primary	Movement in X, Y, Z planes	absoluate measurement of extent of movement of each tooth in each plane	18 weeks
Primary	Little's irregularity index	Little's irregularity index could potentially be used in epidemiological surveys as a valid method to quantify change in tooth alignment less time-consuming measurement of crowding	18 weeks
Primary	Discomfort	Online survey will evaluate discomfort arising from the orthodontic brackets between patients in the two groups	18 weeks
