The purpose of this study was to evaluate the Denture Frame Analysis.
This adjunctive cephalometric analysis of the lateral headfilm was int
roduced in Japan, but no data exist for the Caucasian population at pr
esent. One-hundred-and-six Caucasians were randomly selected and assig
ned to one of four groups, according to their malocclusion: Angle Clas
ses I, II, and III, and anterior open bite. Statistical testing showed
significant differences among the four groups for most of the measure
ments investigated. The Denture Frame Analysis distinguished the diffe
rent types of malocclusion, and evaluated skeletal and dental relation
ships. The occlusal plane aids in the determination of the objectives
and limits of orthodontic therapy.
