Cluster centroids. Clusters 1 and 2 represent borderline CIII phenotypes with a combination of mild maxillary retrognathism and mandibular prognathism, yet with either a flat or a normal mandibular plane, respectively. Cluster 3 corresponds with the vertical CIII phenotype with a large mandible expressed vertically. Cluster 4 and Cluster 5 represent the severely mandibular prognathic and severely maxillary retrognathic phenotypes, respectively.
