nvisalign* was initially developed to correct mild-to-moderate crowding, to close naturally occurring spaces, and to produce dental tipping. 1,2 After years of experience with the system, orthodontists have reported its successful use in more complex cases, such as those involving extractions, open bites, and Class II malocclusions. 3-7 This article describes two anterior open-bite patients who...

BACKGROUND The aim of this study was to determine the effect of the maxillary posterior dentoalveolar discrepancy (MPDD) on the angulation of maxillary molars in open bite subjects. METHODS Pre-treatment lateral cephalograms of 90 young adults with skeletal open bite were examined. The sample initially included six groups categorized according to MPDD condition (present or absent) and sagitta...

In an effort to identify the frequency and differences in the dental and skeletal components of a large sample of adults with Class III malocclusion, with and without open bite, 176 subjects, one half of whom had an anterior open bite, were evaluated. These subjects were chosen by looking at the lateral cephalometric radiographs that were taken of 302 adults (128 men and 174 women) who exhibite...

The present case report addresses the treatment of an Angle Class II malocclusion in an adult female patient, long face pattern, with posterior open bite and dental arches extremely expanded, due to previous treatment.
