Extrusion of the ectopic maxillary canine using a lower removable appliance
Summary
Early intervention for ectopic maxillary canines is crucial. Removing deciduous canines before age 11 can correct impaction in most cases, preventing incisor resorption.
Area of Science:
- Dentistry
- Orthodontics
- Pediatric Dentistry
Background:
- Ectopic eruption and impaction of maxillary canines are common, affecting 0.92% to 2.2% of the population.
- Most cases (85%) involve palatal impaction, while 15% are buccal.
- Permanent incisor resorption due to ectopic canines occurs in 0.71% of 10-13 year olds.
Observation:
- Early recognition of ectopic canine eruption is vital.
- Interceptive removal of deciduous canines before age 11 can normalize permanent canine position in 91% of cases when the crown is distal to the lateral incisor midline.
- Maxillary canine impaction can lead to incisor root resorption as early as age 10, most frequently between 11-12 years.
Findings:
- A removable appliance with light elastics effectively moves impacted canines posteriorly, then vertically and buccally.
- A bonded gold chain provides traction for guided eruption.
- This method ensures eruption into attached mucosa with normal crown length.
Implications:
- Early detection and interceptive treatment of ectopic maxillary canines can prevent significant dental complications.
- Removable appliances offer a viable treatment for correcting canine impaction and preventing incisor damage.
- Guided eruption techniques promote favorable outcomes for impacted teeth.
