Introduction: The purpose of this study was to investigate the relationship between vertical facial pattern and dental arch forms in class II skeletal malocclusion. Materials and Methods: The study comprised of 60 pretreatment (lateral cephalogram, dental cast and photographs) aged between 11-38 years full permanent dentition without agenesis and/or tooth loss except third molar. The evaluation of the dental arch form was performed using a computer analysis (AutoCad). Results: Assessment of interexaminar reliability analysis was performed using Kappa statistic. Pearson correlation was used to analyze the dental arch form and facial vertical dimensions. Conclusion: As the form of dental arches is associated with the vertical growth patterns, it would be desirable to use individualized arches for each patient.
