An important preprocess in computer-aided orthodontics is to segment teeth from the dental models accurately, which should involve manual interactions as few possible. But fully automatic partition of all not a trivial task, since occur different shapes and their arrangements vary substantially one individual another. The difficulty exacerbated when severe malocclusion crowding problems occur, common occurrence clinical cases. Most published methods this area either are inaccurate or require...

To introduce and evaluate the clinical effects of digital surgical guide plate technology in combined osteotomy reconstruction pre-bent position (CORPPP) technique during mandibular segmental resections.Seven cases resection with simultaneous vascularized free fibula flap by oral maxillofacial surgery were selected (Xiangya Hospital, Changsha, China; June 2015 through December 2015). Cone-beam computed tomographic (CBCT) spiral CT scans mandibles fibular donor sites, respectively, collected....

Abstract Mandibular tumors and radical oral cancer surgery often cause bone dysmorphia defects. Most patients present with noticeable mandibular deformations, doctors have difficulty determining their exact morphology. In this study, a deep convolutional generative adversarial network (DCGAN) called CTGAN is proposed to complete 3D cone beam computed tomography data from CT data. After extensive training, was tested on 6 tumor cases, resulting in virtual completion. We found that can...

Computer-assisted and template-guided mandibular reconstruction provides higher accuracy less variation than conventional freehand surgeries. The combined osteotomy pre-shaped plate position (CORPPP) technique is a reliable choice for reconstruction. This study aimed to evaluate the of CORPPP-guided fibular flap analyze possible causes deviations.From June 2015 December 2016, 28 patients underwent Virtual planning personalized templates were applied in 15 while 13 received Deviations during...

Focusing on the problems existing in campus network management systems (NMS), this paper introduces a core concept of modern - participative into management, and presents new user participating which is composed by center subsystem consumer subsystem. These two subsystems run cooperatively. In practice, user-participation can effectively decrease operation cost, improve level service quality.

Skeletons as important shape features of an object are useful for description. Unfortunately, methods obtaining skeletons a grayscale volume lacking due to no clear boundary between and background. In this paper, we present new segmentation-free skeletonization method on volumes based marching cubes, topological thinning novel pruning routine. Our is capable generating family skeletal curves surfaces that lie centered at rod-like plate-like parts in the It demonstrated biomedical datasets.

The growth of industrial intelligence has led to greater automation in numerous sectors. As robots are becoming increasingly prevalent, companies must confront the essential matter how employ them supplant manual labour, ultimately heightening productivity and efficiency. This paper outlines development an automated vibration robot comprising a vertical cell, rail-type inclined insertion system, other cells working collaboration. uses box girder as foundational framework conducts field...

Aim 'This study aims to establish an open-source algorithm using Python analyze the accuracy of guided implantation, which simplifies interstudy comparisons. Methods Given ≥3 landmark pairs, this Tri-Point (TriP) method can register images. With ≥4 TriP calculate system errors for image registration. We selected 8 indicators from literature. Considering development in new bone on cone beam computed tomography (CBCT), we added apical rectified deviation (ARD) and coronal (CRD), providing...
