Deepbite Malocclusion: Analysis of Underlying Components in Different Facial Growth Patterns

Background: Deep bite malocclusion should not be approached as a disease entity; instead, it should be viewed as clinical manifestation of underlying discrepancies. The present study aim to evaluate parameters of deepbite in various growth patterns. Materials and Methods: Sample of 90 patients divided into groups of varying growth patterns: Vertical (FMA=27°), Horizontal (FMA=22°), Normal (FMA 22°-27°), were studied for cephalometric and dental measurements. Results:Curve of spee was major contributor to deep bite in all growth patterns. Gonialangle, and maxilla mandibular alveolar base heights were correlated with deep bite in horizontal growers. Inclination of maxillary and mandibular incisors was responsible for deep bite in vertical growth pattern. Conclusion: This analysis of deep bite components could help clinicians design individualized mechanotherapies based on underlying cause, rather than being biased toward predetermined mechanics when treating deep bite malocclusion. Hence, orthodontists should look for not just leveling of curve of spee but also the growth pattern of patient.
