Geometrical models of the craniofacial structures and rapid maxillary expanders of the patient with UCLP: a Construction of skull model with sutures; b finite element meshes of the craniofacial structures in different sizes of tetrahedrons; c C-RPE, the conventional tooth-borne rapid maxillary expander (Hyrax expander); d B-RPE, bone-borne rapid palatal expander anchored by micro-implants (8.5 mm length, 1.8 mm diameter) on the palatal slope, with the miniscrews 8 mm beneath the alveolar ridge, between the first and second premolars (the anterior part), the first and second molars (the posterior part)
