ABSTRACT


Aim

To evaluate the use of Third Class Resolver (TCR), a new fixed and functional orthopaedic appliance for the treatment
of skeletal Class III malocclusion in adolescents and young adults.

Methods

Study Design: Retrospective
analysis. Twenty subjects, 10 females and 10 males, affected by Class III malocclusion were treated with a new fixed orthopaedic
appliance: the Third Class Resolver (TCR). The mean age was 7 years at the beginning of treatment and 9 years at the end of
treatment. The mean treatment time was 6 months. Digital cephalometric superimpositions on lateral radiographs taken at the start and
end of treatment were assessed. The cephalometric values were statistically analysed.

Results

Cephalometric analysis of changes
during treatment shows a statistically significant increase of ANB angle (mean 1) (P=0.045); increase of Witts Index (mean 3.5 mm)
(P=0.003); decrease of Maxillo-Mandibular angle (MM) (mean -2.3) (P=0.047); increase of Upper incisor-Maxilla Plane angle (angle
mean 10.5) (P=0.02); increase of the distance between Upper Incisor and A-Pg line (mean 2.4 mm) (P=0.021); increase of the
mandibular branch length (mean 4.8 mm) (P=0.004).

Conclusion

TCR can be used fully for treatment of Class III
malocclusions.
