We evaluated the algorithm both qualitatively and quantitatively using manually labeled datasets, relevant comparator software solutions cited in the literature, and expert evaluations. The computational tools and atlases described in this paper will be distributed to the research community as part of the FreeSurfer image analysis package.Inter-alveolar augmented corticotomies with bone grafting may be used before orthodontic treatment in cases of root out or in major proclination movements in the lower anterior region. Bone graft particle spreading with reduced confinement and strong labial muscle contractions may cause graft resorption. Herein we describe a combined orthodontic corticotomy technique involving periosteal flap grafting confinement and a surgical muscle-weakening flap to avoid resorption.The management of patients with dento-maxillofacial deformities is based on assessments of the dental occlusion - facial skeleton - soft tissues triad. As societal demands and surgical practices have evolved, facial soft tissues have moved to the forefront of considerations in orthognathic surgery. Techniques are therefore required to analyze facial soft tissues objectively and reproducibly, for diagnosis, preoperative planning, and follow-up. Several technologies are currently capable of providing three-dimensional (3D) models of the face, either by 3D reconstruction of traditional computed tomography or cone beam computed tomography data, or directly by stereophotogrammetry, laser scanning or structured light scanning. Multimodal image registration techniques allow bone base, dental occlusion and facial soft tissue information to be combined in a 3D virtual patient. Three-dimensional cephalometric analysis of the facial skeleton and skin is now perfectly integrated in virtual planning and is gradually gaining in automation and accuracy. Photorealistic 3D simulations allow optimal soft tissue planning and facilitate physician-patient communication. Finally, these facial modeling techniques facilitate post-operative studies of soft tissues, which generally involve comparisons of volumetric data. There are many research avenues to pursue and technical improvements are to be expected, particularly through the development of big data and artificial intelligence approaches.Introduction Le Fort I osteotomy procedures requires miniplates fixation in both the aperture piriformis and zygomaticomaxillary buttress. Purpose The purpose of this study was to compare the postoperative stability of the Le Fort I osteotomy using four-plate versus two-plate fixation. Material and methods This study involved 39 Class III patients who underwent one-piece Le Fort I osteotomy with bilateral sagittal split ramus osteotomy. In group I, four miniplates were placed at the apertura piriformis and the zygomaticomaxillary buttress, whereas, in group II, fixation was achieved with two miniplates bilaterally placed at the piriform apertura with no posterior fixation. Linear and angular measurements included maxillary sagittal and vertical positions. The primary outcome of this study was stability, as recorded by lateral cephalometric measurements of the preoperative, immediately postoperative and late postoperative periods. Results Significant immediate postsurgical changes were found in both groups. In the late postoperative cephalometric measurements, all skeletal parameters showed significant stability in groups I and II. In terms of vertical and sagittal relapse, there was no significant difference between the four-plate and two-plate groups (p1=0.686 and p2=0.513, respectively). Conclusion A good postoperative stability can be obtained with a two-plate fixation after one-piece Le Fort I osteotomy.Ghost images are artefacts of anatomical structures or foreign objects that oral and maxillofacial surgeons should take into consideration to prevent misdiagnosis and mistreatment.
