Online published on 6 March, 2013. Abstract The relationship between genetic and non-genetic factors i.e. nature versus nurture in the etiology of dentofacial variation and malocclusion has previously been studied in both twin and family investigations. Genetics is believed to be the sole factor for the etiology of anterior open bite malocclusion although environment also constitutes an important contributing factor. The comparison of monozygotic twins is frequently used to partition variance of quantitative traits into environmental and genetic factors. In this study different cephalometric variables were compared amongst a pair of monozygotic twins. The purpose of this study was to assess the variation of craniofacial complex of monozygotic twins with anterior open bite malocclusion.
