Abstract
BackgroundSuccessful treatment of patients with multiple bilateral impactions can be an orthodontic challenge, but few reports on treatment planning and execution exist.Case presentationIn 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.ConclusionsThe presented treatment approach thus proved to be highly effective in cases with multiple bilateral impactions with minimal side effects and considerably reduced treatment time.

A successful treatment of cases with multiple impactions poses a major challenge for most orthodontists in clinical practice and requires a meticulous treatment planning, preferably in collaboration with a dental surgeon
Summary
The presented combined surgical-orthodontic treatment procedure with the EWCTM traction system enabled an efficient and controlled uprighting and buccal eruption of the formerly palatinally impacted canines and the premolars with good rotational control during traction.
