The Journal
Over the years many fixed functional
appliances have been used by orthodontists
and only a few have shown well acceptance and
favourable results on the patient (Cope et al,
[6],[7]
1994; Karacay et al, 2006) . Forsus appliance
which has been recently introduced, is well
accepted showing stable results (Heinig & Goz,
2001) [8] .
The case reported in this article is a young male
patient at the late stage of the puberty with
skeletal class II malocclusion due to mandibular
retrusion.
It has been shown that fixed functional
appliances enhance mandibular growth and
that they tend to produce a more horizontal
condylar growth compared with removable
functional appliances. The case was treated
with fixed functional appliance using Forsus
fatigue resistance appliance. FDR typically
demonstrate mesial movement of the
mandibular molars, tipping of the mandibular
incisors, and variable effects associated with
[9]
mandibular growth . The post treatment results
showed significant improvement in the facial
profile (ANB 30) and class I molar relationship
with ideal overjet and overbite.
