Abstract

Impacted and Ectopic Teeth: Orthodontic Management

Impacted teeth are a relatively common dental anomaly. However, their treatment is usually long and complicated due to many factors that are not present in routine orthodontics. Some of these factors are related to pathology of the tooth itself, but others are dependent on us, the orthodontists. Understanding how to interpret 3-dimensional imaging is crucial for accurate diagnosis of pathology, root shape, length and integrity and location of the impacted tooth and also resorption of the adjacent roots. Since surgical exposure is usually required to access the impacted tooth, close cooperation between the orthodontist and the oral surgeon is mandatory for planning the best surgical approach, with minimal damage to hard and soft tissues. A reliable anchorage unit which allows application of controlled directional forces with minimal side effects on the anchorage teeth must be build-up. Mechanotherapy is challenging due to the need for complex movements, especially torquing the roots of extremely displaced teeth. With so many things that can go wrong, prognosis of treatment becomes uncertain. This lecture will discuss some of the key factors in determining a successful outcome in different types of impactions, with special emphasis on the importance of early diagnosis and timing of initiation of orthodontic treatment.
