Abstract

Management of Ectopic Eruptions and Impacted Teeth. As
many scenarios as you can think off
Carol Weinstein, Miguel Hirschhaut.

Ectopic eruptions manifest in diverse clinical scenarios with varying severity.
Sometimes, monitoring eruption alterations allows for early intervention and
simpler treatments. Interceptive approaches, such as removing obstructions or creating
space, can prevent more complex and invasive procedures. However, when simple
measures like supernumerary removal, space gaining, or deciduous tooth extraction fail,
surgical-orthodontic interventions are necessary to address dental impactions stemming
from eruption abnormalities. Impactions often require more complex treatments. This
comprehensive review covers ectopic eruptions and impactions of all teeth, from
maxillary incisors to mandibular second molars, detailing both interceptive and
corrective strategies. It emphasizes clinical evaluation and contemporary imaging
while thoroughly explaining mucogingival considerations and orthodontic
biomechanics.
Different approaches to impactions in the orthodontic treatment, such as open and
closed eruption, Gopex, miniscrews as an anchorage, and alternative case-based
protocols are described. Complications and solutions for dental impactions are
illustrated tooth by tooth, providing practical guidance for managing these
common clinical challenges.
