Ectopic eruption is defined as abnormal eruption and results in malpositioned teeth and
abnormal root resorption of adjacent teeth. Ectopic eruption, first reported by Chapman,
occurs in 3% of the population and that mostly in the maxilla. Etiologic factors include
narrow maxilla, large maxillary teeth, retarded calcification of the first molar, inclined
eruption path of the first molar and retruded position of the maxilla.
Impaction of the second molar is rare and occurs mostly in the mandible. Major causes
are large teeth and insufficient arch length.
Halterman has devised a method of distalizing a ectopically erupting first molar by
cementing a band on the second deciduous molar with a hook soldered and a button
bonded to the occlusal surface of the first permanent molar.
Ectopically erupted posterior teeth should be treated early to maintain normal
development of the dentition, harmony of facial growth and occlusal support, a failure to
do so could result in severe malocclusion, periodontal damage and continued root
resorption of the adjacent teeth. Early detection and treatment is thus vital.
The author is submitting this report as he has obtained favorable results in treating a
patient who came to the SNUDH Dept. of Pediatric Dentistry complaining of the first
molar by using a modified Halterman appliance.
