Summary

The purpose of this research is to test which of four clear aligner attachment types is more efficient in extruding (erupting) maxillary lateral incisors vertically into correct position during orthodontic treatment.

Detailed description

Attachments are small tooth-colored shapes that are bonded (attached) to teeth before or during treatment with clear aligners. They are like handles, giving aligners something to gently push teeth into correct positions. There are 4 different shapes of attachments that are commonly used to extrude lateral incisors (incisally-beveled, gingivally-beveled, optimized and horizontal). All 4 of these attachments are successful in extruding lateral incisors but there is not enough research evidence to know for sure which attachment would be ideal for a specific circumstance.

Conditions

• Maxillary Lateral Incisor Malocclusion

Interventions

Type	Name	Description
DEVICE	Incisally-beveled attachment	Incisally-beveled attachments will be bonded to teeth before or during orthodontal treatment with clear aligners
DEVICE	Gingivally-beveled attachment	Gingivally-beveled attachments will be bonded to teeth before or during orthodontal treatment with clear aligners
DEVICE	Optimized attachment	Optimized attachments will be bonded to teeth before or during orthodontal treatment with clear aligners
DEVICE	Horizontal attachment	Horizontal attachments will be bonded to teeth before or during orthodontal treatment with clear aligners
