To evaluate the use of Second Class Resolver (SCR), a new fixed orthopaedic appliance, for the treatment of skeletal
Class II malocclusion in growing subjects.
Design Retrospective analysis. Forty subjects were treated
with Second Class Resolver (SCR). The mean age was 8 years at the beginning of treatment and 10 years at the end of treatment.
Digital cephalometric superimpositions on lateral radiographs taken at start and end of treatment were assessed. The cephalometric
values were statistically analysed.
Cephalometric analysis of changes during treatment shows reduction of ANB angle
(mean 2); reduction of Witts Index (mean 3 mm); reduction of Maxillo-Mandibular angle (MM) (mean 1); reduction of SNA (angle mean
3); reduction of gonial angle (mean 1.8); increase of the mandibular branch length (mean 5 mm); increase of mandibular body (mean
The Second Class Resolver can be beneficially used for the treatment of Class II malocclusion.
