You will receive 1 credit(s) of continuing education credit upon successful completion of this course. The purchase price of this course is $41.00

Description:
This course discusses the management of abnormally positioned tooth eruption.

Author:

Learning Objectives:

Upon completion of this course, participants should be able to do the following:

  1.  Assist the clinician in early recognition and diagnosis of ectopic eruption of permanent molars.
  2. Discuss the etiology of ectopic eruption and facilitate recognition of reversible and irreversible forms of ectopia.
  3. Describe the techniques and modalities available for clinical intervention of ectopic eruption of permanent molars.
  4. Explain the use of specific appliance therapy, including interproximal wedging techniques and distal-tipping mechanics.

Abstract:

Ectopic eruption can be defined as a tooth erupting in an abnormal position or orientation. The maxillary first permanent molar is the most commonly affected tooth. Correction of ectopically erupting permanent molars is critical for the development of a stable occlusion and is an important component of interceptive orthodontic treatment. The clinician can choose from a variety of effective treatment modalities to manage ectopically erupting permanent molars successfully.
