Occlusal alterations in unilateral coronal craniosynostosis.
Int J Oral Maxillofac Surg. 2011 Aug; 40(8):805-9.IJ

Abstract

There are few studies on maxillomandibular skeletal alterations. Twenty-one patients with unilateral coronal craniosynostosis were analysed and compared with controls. Landmarks analysed were: sella-nasion-point A and B angles, point A-nasion-point B angle, interincisal angle, angle of superior incisor axis on the sella-nasion plane, lower incisor to mandibular plane angle, Frankfort mandibular plane angle, zygomatic-frontal suture (Z), point on the most concave part of pyramidal apophysis of the upper maxilla (Mx), antegonial incisure (AG), upper (UMT) and lower (LMT) molar teeth. Differences were significant for class II dentoskeletal occlusion (p<0.0001), mandibular hyperdivergence (p<0.0001), lingualization of superior incisor (p<0.005), deviation of inferior interincisal contralateral line to the synostosis (p<0.0001) in the plagiocephalic population. Compared with contralateral counterpoints, Z (p<0.05), Mx (p<0.005) and UMT (p<0.0005) on the affected side were closer to the midline; AG (p<0.0005) and LMT (p<0.05) were further from it. On the frontal plane, Z, Mx, UMT, LMT and AG on the affected side were higher. Vertical and transversal contraction of the jaw of the synostotic side and laterodeviation of the mandibular interincisal line of the contralateral synostotic were clear. The altered position of the glenoid cavity, anteriorized in unilateral coronal craniosynostosis, could be the cause of mandibular dentoskeletal asymmetry.
