-Abstract-
Many treatment approaches of Cl ¥² malocclusion have been introduced and the choice
of treatment should be a function of the individual problem, not of the clinician(personal
preference, experience and success rate of the operator). Therefore a function of the
individual problem should be analysed exactly. Much has been written in the orthodontic
literature concerning the nature of Cl ¥² malocclusion. It has been reported by many
investigators that a Cl ¥² malocclusion occurs in a variety of skeletal and dental
configurations by differences of race and age. Lateral cephalometric radiographs of 125
individuals were studied for the presence and distribution of four horizontal components
and one vertical component in a manner similar to McNamara.
The results were as follows
1. Cl ¥² malocclusion is not a single clinical entity. It can result from numerous
combinations of skeletal and dental components.
2. Maxillary skeletal retrusion was the most common single characteristic of the Cl ¥²
sample.
3 Only a small percentage or the cases in this cases in this study exhibited maxillary
dentoalveolar protrusion.
4. Only a small percentage of the cases in this study exhibited mandibular dentoalveolar
dentoalveolar retrusion.
5. Mandible was usually well-positioned, but a wide variation was observed.
6. A large percentage of the cases in this study exhibited excessive vertical
development.
Thus, it appears that in designing the ideal treatment regime, those approaches which
might restrict vertical development and promote maxillary horizontal growth could be
more appropriate in many cases.
