Introduction: Open and Deep bite malocclusions should not be approached as disease entities; instead, they should be viewed as a clinical manifestation of underlying discrepancies. The aim of this study was to investigate the various skeletal and dental components contributing to vertical malocclusion, the significance of contribution of each, and if there are significant differences between their contributions in deep and open bite malocclusions.
Methods: Dental and skeletal measurements were made on lateral cephalometric radiographs and study models of 203 patients with deep or open bite. These measurements were statistically analysed.
Results: The discrepancy in the curve of Spee was the greatest shared dental component (76.4%), significantly higher than any other component (P = 0.00000). The gonial angle angle was the greatest shared skeletal component (45.8%), highly significant compared with the maxillary base angulation (P = 0.01988). When open and deep bite malocclusions were compared, the mandibular plane angle and the angulation of upper incisors (P = 0.00000) were highly sharing in open bite, while the eruption of the upper incisors and posterior teeth (P = 0.00000) were highly sharing in deep bite.
Conclusions: The discrepancy in the curve of Spee and the gonial angle were the greatest contributing components. This analysis of deep and open bite components could help clinicians design individualized mechanotherapy’s based on offending cause, rather than being biased toward predetermined mechanics.
