Abstract
|
|
|
A scissors bite in the posterior teeth occurs when the upper teeth are positioned totally or unilaterally buccal to the lower teeth in centric occlusion.
This malocclusion can result from either excessive width of maxilla, deficient width mandible, or combination of both. The malocclusion can lead to hindered growth of jaws or to asymmetry between the jaws. Besides, the severe lingual inclination of the mandibular posterior teeth prevents adequate mastication. Thus, the scissors bite is in need of immediate interceptive orthodontic interbention.
The common treatments of the scissors bite is to expand the mandibular arch: fixed or removable appliances. In our clinic, we made a seccess in treatment of the scissors bite using the Schwarz appliance. We treated the scissors bite using the lower Schwarz appliance for a mean observation period of 21 months.
The subjects were 2 boys, aged 4 years.
