Objective: To evaluate the correlation between the degree of mandibular incisor crowding, lower incisor position and vertical craniofacial configuration in different malocclusions. Study Design: Cross-sectional analytical study. Place and Duration of Study: Orthodontics department, Armed Forces Institute of Dentistry, Rawalpindi Pakistan, from Jan to Dec 2018. Methodology: This study was conducted on 100 pre-treatment study casts and lateral cephalographs of orthodontic, aged 10 to 26 years. Patients who presented with complaints of lower incisors crowding were included in the study. The cephalogram tracings, calculations and lower incisor crowding measurements were taken. All the fifteen parameters of vertical craniofacial configuration, lower incisors position and sagittal skeletal base relationship were measured. Result: Out of 100 patients, 45 were males and 55 were females with a mean age of 16.11 ± 3.53 years. According to this study, there was no statistically significant correlation between the degree of lower incisor crowding and vertical facial proportions and incisor position in studied malocclusions. Conclusion: The lower incisor crowding was a local and independent discrepancy. It was a frequently encountered problem, successful therapy depends upon several contributing factors that must be identified for successful management.
