ABSTRACT


Aim

This was to clarify dentoalveolar, skeletal and facial profile modifications induced by Frnkel II
functional treatment in Class II division 1 subjects in prepubertal stages CS1-2.

Methods

Evaluation of
25 caucasian subjects (15 males, 10 females), mean age 8y 11m, in vertebral stages CS1-2. The mean duration of functional
treatment was 1y 11m. Study Design: Prospective controlled study. The sample was evaluated at T0, start of treatment, and T1,
end of Frnkel II therapy. Untreated subjects in Class II division 1 were the control group. Statistics: T-test for paired
data was calculated before and after treatment (P< 0.05).

Results

A statistically significant increase between T0 and T1
was obtained for SNB (p 0.022), ANB (p <0.001), Mx/Mn differential (p 0.001), Co-Go-Me (p 0.014), OJ (p < 0.001), OB (p 0.042), IMPA (p 0.021) . OJ (p < 0.001) and OB (p 0.003) showed a higher significant change in the Frnkel group compared to control group.

Conclusion

The Frnkel II
appliance produced, in CS1-2 subiects, significant effects in teeth position, skeletal modifications and soft tissue changes,
although the pubertal growth spurt would occur at least two years later.
