Introduction
A deepbite malocclusion should not be approached as a disease entity; instead, it
should be viewed as a clinical manifestation of underlying discrepancies. The aim
of this study was to investigate the various skeletal and dental components of deep
bite malocclusion, the significance of the contribution of each, and whether there
are certain correlations between them.
Methods
Dental and skeletal measurements were made on lateral cephalometric radiographs and
study models of 124 patients with deepbite. These measurements were statistically
analyzed.
Results
An exaggerated curve of Spee was the greatest shared dental component (78%), significantly
higher than any other component (P = 0.0335). A decreased gonial angle was the greatest shared skeletal component (37.1%),
highly significant compared with the other components (P = 0.0019). A strong positive correlation was found between the ramus/Frankfort horizontal
angle and the gonial angle; weaker correlations were found between various components.
Conclusions
An exaggerated curve of Spee and a decreased gonial angle were the greatest contributing
components. This analysis of deepbite components could help clinicians design individualized
mechanotherapies based on the underlying cause, rather than being biased toward predetermined
mechanics when treating patients with a deepbite malocclusion.
