..The purpose of this study was to determine whether the surgical outcomes achieved with computer-aided surgical simulation (CASS) are better than those achieved with traditional methods...

..The study was designed to answer 2 questions: 1) whether the weight of the new device can negatively influence the NHP and 2) whether the new method is as accurate as the gold standard...

..Finally, our method was validated using 12 sets of digital dental models. The results showed that using our method the digital dental models can be accurately and effectively articulated to MI position...

..To evaluate and summarize the evidence comparing nonsurgical therapies in the treatment of infants with deformational plagiocephaly...

..The purpose of this retrospective study was to present the results of the authors' microscopic minimally invasive approach in the treatment of nonsyndromic craniosynostosis...

..The purpose of this study was to establish clinical feasibility of our 3-dimensional computer-aided surgical simulation (CASS) for complex craniomaxillofacial surgery...

..The purpose of this pilot study was to evaluate the accuracy of this technique in the treatment of patients with complex CMF deformities...

..This discrepancy was caused by a clockwise rotation of the maxilla during the distraction. Finally, the study showed a variable relapse rate not previously reported in maxillary distraction...

..To evaluate the outcome of presurgical nasoalveolar molding (PNAM) therapy in the treatment of patients with nonsyndromic unilateral cleft and palate (UCLP)...

..The purpose of the present study was to evaluate the accuracy of our newly developed approach to digital dental model articulation...

....

..To evaluate the long-term effectiveness of helmet therapy in the correction of deformational plagiocephaly and to assess the early occlusal abnormalities seen in these patients...

..The distractors were removed 3 months after surgery. Results showed that the patient's severe maxillary hypoplasia was corrected as predicted and there was excellent new bone formation between the edges of the osteotomy...

..The goal of this study was to create a model for human mandibular movement prediction based on the geometry of the mandible...

..The purpose of this study is to assess the costs and benefits of computer-aided surgical simulation (CASS) and to compare it with the current surgical planning methods for complex cranio-maxillofacial (CMF) surgery...

..The authors note that critical to this approach is the postoperative helmet therapy. Early results are encouraging...

..If treated early (at < 12 months of age), head shape in these patients can be normalized by molding helmet therapy. Surgery is reserved for older patients (> 12 months of age) or those with sagittal synostosis...

..99 mm for the experienced examiner and 2.88 mm for the inexperienced examiner. CONCLUSION: The error of both manual and LS-5 methods was within 0.5 mm. The LS-5 method had its advantage because it could be automated by the computer...

..Helmet therapy is more effective in children with posterior positional plagiocephaly than in children with positional brachycephaly...

..The purpose of this study was to develop a motion simulator capable of recreating and recording the full range of mandibular motions in a cadaveric preparation for an intact temporomandibular joint (TMJ) and after total joint replacement...

..The purpose of this study was to evaluate the long-term effectiveness of presurgical nasoalveolar molding (PNAM) in patients with unilateral cleft lip and palate (UCLP)...

..To test the hypothesis that facial symmetry affects both 2-dimensional (2D) and 3-dimensional (3D) cephalometric measurements...

..The purpose of this article is to present this surgical planning process and discuss its use in maxillary and midface distraction...

..After this, the bending rigidity of the pins increased significantly. CONCLUSION: The 2.0-mm steel pins used in most external multiplanar distractors are not capable of overcoming the tissue resistance to linear or angular distraction...

..The goal of this paper is to evaluate the immediate effects of RME with Hyrax appliances on the dentoalveolar complex using cone beam computed tomography (CBCT)...

..1 to 1.1 degrees, indicating no clinical significance. The authors concluded that our technique could accurately and repeatedly record NHP three-dimensionally and transfer it to a three-dimensional CT head model...

..As a result, the changes associated with presurgical nasoalveolar molding therapy help decrease the complexity of subsequent surgeries...

..The present analysis allows the accurate measurement of the size, shape, position, and orientation of the different facial units and incorporates a novel method to measure asymmetry...

..The purpose of this prospective multicenter study was to assess the accuracy of a computer-aided surgical simulation (CASS) protocol for orthognathic surgery...

..Moreover, in the ADD group, the posterior condylar displacement was noted to be 2.4 times greater than the superior condylar displacement...

..Thus, our model is biomechanical relevant and statistical relevant. Validation on eleven patients demonstrates the effectiveness and efficiency of our method...

..Therefore, molding helmet therapy maintains the operative correction obtained and promotes more normal cranial growth patterns...
