Interceptive management of impacted canines in early mixed dentition: a paradigm shift in orthodontics.

The topic of upper canine impaction has been a constant in orthodontic literature. Many authors have investigated and discussed upper canine impaction and often similar types of treatment approaches have been explored in different phases of dental development. Most researches still point out the lack of evidence to support one interceptive treatment above the other and wish more randomized controlled trials would be organized.

Aims, Objectives and Learning Outcomes:

Aims: To investigate the effect of three well known interceptive interventions in a randomized controlled trial on maxillary canine impaction in early mixed dentition.

Objectives: This lecture will provide evidence for the most optimal treatment approach of upper canine impaction in early mixed dentition.

Learning outcomes: Delegates will learn how to diagnose potential risk of upper canine impaction in early mixed dentition and what interceptive treatment is most effective in facilitating upper canine eruption in the long run.
