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. Valproate 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. A 38-year-old male patient referred to our clinic for dental implant treatment. Orthopantomograph (OPG) revealed an impacted distomolar at the apex of maxillary right third molar and an ectopic supernumerary tooth in the left maxillary sinus. Despite the ectopic supernumerary tooth appearance on OPG, cone beam computed tomography images revealed that there was not a supernumerary tooth in the left maxillary sinus. Nasal cavity and paranasal sinuses in field of view were evaluated and maxillary ostium diameters were measured to detect if the tooth had migrated. The tooth appearance on the OPG was determined as a ghost image of the impacted distomolar at the contralateral side. Following the extraction of the distomolar, another OPG was performed and the ghost image was disappeared.Rhodnius pallescens is the principal vector of Chagas disease in Panama. Recently a dark chromatic morph has been discovered in the highlands of Veraguas Province. Limited genetic studies have been conducted with regards to the population structure and dispersal potential of Triatominae vectors, particularly in R. pallescens. Next generation sequencing methods such as RADseq and complete mitochondrial DNA (mtDNA) genome sequencing have great potential for examining vector biology across space and time. Here we utilize a RADseq method (3RAD), along with complete mtDNA sequencing, to examine the population structure of the two chromatic morpho types of R. pallescens in Panama. We sequenced 105 R. pallescens samples from five localities in Panama. We generated a 2216 SNP dataset and 6 complete mtDNA genomes. RADseq showed significant differentiation among the five localities (FCT = 0.695; P = .004), but most of this was between localities with the dark vs. light chromatic morphs (Veraguas vs. Panama Oeste). The mtDNA genomes showed a 97-98% similarity between dark and light chromatic morphs across all genes and a 502 bp insert in light morphs. Thus, both the RADseq and mtDNA data showed highly differentiated clades with essentially no gene flow between the dark and light chromatic morphs from Veraguas and central Panama respectively. We discuss the growing evidence showing clear distinctions between these two morpho types with the possibility that these are separate species, an area of research that requires further investigation. Finally, we discuss the cost-effectiveness of 3RAD which is a third of the cost compared to other RADseq methods used recently in Chagas disease vector research.
