Successful treatment of multiple bilateral impactions - a case report.

BACKGROUND: Successful treatment of patients with multiple bilateral impactions can be an orthodontic challenge, but few reports on treatment planning and execution exist. CASE PRESENTATION: In this case report, we describe the successful orthodontic treatment of a 16.3-year old female patient without systemic or genetic disease with initially nine persisting deciduous and nine impacted permanent teeth with complete root formation and closed apices in both jaws. After extraction of the deciduous and surgical exposure of the impacted permanent teeth, the Easy-Way-Coil system was used in conjunction with a skeletal anchorage (maxilla, BENEfit system) to guide the eruption of all impacted teeth. After a total treatment time of only 22.8 months all impacted teeth could be aligned successfully and a stable and functional class I occlusion was achieved. In addition, there were no adverse treatment effects such as anchorage loss, root resorptions or periodontal problems and an esthetic result could be achieved. CONCLUSIONS: The presented treatment approach thus proved to be highly effective in cases with multiple bilateral impactions with minimal side effects and considerably reduced treatment time.
