Evolution of orthodontic aligners: A narrative review

Clear aligners seem to be a new modality for patients undergoing orthodontic treatment; the initial concept of this treatment evolved in the 20th century. Remensnyder’s “Flex-O-Tite” appliance led to the introduction of the aligner, from this Kesling tooth positioner appliance made up of rubber-based 1945 proposed the concept of using it for minor tooth movements in a sequential series. The purpose of this article is to provide information about chronologically ordered evolution of aligners. Various types of generations and attachments used in different aligner systems. An online search was done using databases from PubMed and Google Scholar to find the articles. Database search was done with the following string: ((aligners [Title/Abstract]) AND (comparison [Title/Abstract])) AND (((fixed appliance [Title/Abstract]) OR (braces [Title/Abstract])) OR (fixed orthodontic appliance [Title/Abstract])). 3 articles are included in the narrative review to evaluate the better outcomes of the treatment effectiveness between fixed orthodontic treatment and aligners with short summary of chronological ordered evolution, generations and attachments of aligners. The overall effectiveness of orthodontic treatment depends upon the knowledge of clinician therefore knowledge about recent advances is important for proper treatment of the patient.

A Biomimetic Sketch-Based Form Finding Tool

Sketches play a fundamental role in the design disciplines, serving as crucial representations for ideation, problem-solving, and communication. In the realm of architecture, sketches encapsulate the evolution of ideas from conceptualization to construction. Hand-drawn sketches, characterized by their open-ended, ambiguous nature and rapid production, stand out as indispensable tools in bridging the gap between abstract concepts and tangible designs, guiding the progression from early design stages to final product realization. However, despite their significant potential and pivotal role in the design process, hand sketches have often been overlooked and swiftly abandoned in the ongoing discourse surrounding traditional versus digital design methodologies, particularly with the widespread integration of computer technologies. This study endeavors to unlock the wealth of information embedded within hand sketches, spanning from initial design concepts to intricate manufacturing details, through the utilization of a hybrid digital form-finding tool. By employing swarm algorithms in the quest for form, it is anticipated that the boundaries of conceptual ideas delineated by hand sketches will be expanded. This is facilitated by an algorithm developed in Processing using the Java coding language, complemented by an intuitive interface. The research journey commences with a comprehensive literature review encompassing biomimetics, sketching techniques, and tools for transitioning hand sketches into digital realms. Subsequently, a thorough elucidation of the algorithm, crafted within the Processing environment, is provided.The efficacy of the tool is assessed through experimentation involving adjustments of various parameters on identical sketches, as well as application to seven architectural sketches representing built designs, with subsequent interpretation of the outcomes. It is posited that the adaptability of the algorithm's core logic, coupled with the development-friendly environment of Processing, holds immense potential for empowering designers to steer sketches in desired directions through tailored enhancements.

Thermal Evaluation of the Initial Concept 3.X Vehicle at Mach 7

High-speed global surface temperature distributions and heat flux measurements on the Initial Concept 3.X vehicle (IC3X) model were investigated at the UTSA Mach 7 wind tunnel, examining angles of attack of 0° and 5° at a freestream unit Reynolds number (Re) ~7 × 106 m−1. A ruthenium-based, fast-responding, temperature-sensitive paint (fast-TSP) prepared in-house was applied to a 7.1% scale model of the vehicle. Static calibration was performed to convert the intensity measurements into surface temperature values. The surface temperatures and derived heat flux fields conformed to the predicted trends, which was corroborated by Schlieren flow visualization. Notably, the average surface temperature variation was identified to range from 6 to 34 K at a 0° angle of attack and from 11 to 44 K at a 5° angle of attack, with the most pronounced gradient detected at the stagnation point. Additional measurements provided a detailed thermal assessment of the model, including estimations of the stagnation point heat flux, the convective heat transfer coefficient, and the modified Stanton number. Statistical and time series analyses of the data collected revealed the absence of prevailing unsteady phenomena, suggesting that the tested design geometry is well suited for hypersonic flight applications. These experimental outcomes not only shed light on the aerothermodynamics experienced during high-speed flight but also underscore the effectiveness of fast-TSP in capturing both quantitative and qualitative thermal data.

Satisfaction with Behavior Trajectory Security Protection in Social Media Intelligent Recommendations

Abstract Intelligent recommender systems provide personalized recommendation for users based on their behavior trajectories. Intelligent recommendation is a double-edged sword with increasing impacts. This study investigates the influencing mechanism of social media users’ satisfaction with behavior trajectory security protection in the context of intelligent recommendation, with the aim of promoting healthy development of mobile social media. This study applied the grounded theory method to identify relations among concepts and categories in terms of three-level coding. During open coding, 271 initial concepts and 26 subcategories were elicited; during axial coding, 10 categories were elicited; and during selective coding, relations among categories were identified and a theoretical model was developed. The results indicate that satisfaction with behavior trajectory security protection is directly influenced by security protection information quality, security protection system quality, security protection service quality, net benefits, external support, privacy concerns, and privacy cognitive biases. Privacy literacy has direct impacts on privacy concerns and privacy cognitive biases. Meanwhile, herd behavior directly impacts privacy concerns. Implications for theory and practice are discussed.

A Preclinical Trial Protocol Using an Ovine Model to Assess Scaffold Implant Biomaterials for Repair of Critical-Sized Mandibular Defects.

The present work describes a preclinical trial (in silico, in vivo and in vitro) protocol to assess the biomechanical performance and osteogenic capability of 3D-printed polymeric scaffolds implants used to repair partial defects in a sheep mandible. The protocol spans multiple steps of the medical device development pipeline, including initial concept design of the scaffold implant, digital twin in silico finite element modeling, manufacturing of the device prototype, in vivo device implantation, and in vitro laboratory mechanical testing. First, a patient-specific one-body scaffold implant used for reconstructing a critical-sized defect along the lower border of the sheep mandible ramus was designed using on computed-tomographic (CT) imagery and computer-aided design software. Next, the biomechanical performance of the implant was predicted numerically by simulating physiological load conditions in a digital twin in silico finite element model of the sheep mandible. This allowed for possible redesigning of the implant prior to commencing in vivo experimentation. Then, two types of polymeric biomaterials were used to manufacture the mandibular scaffold implants: poly ether ether ketone (PEEK) and poly ether ketone (PEK) printed with fused deposition modeling (FDM) and selective laser sintering (SLS), respectively. Then, after being implanted for 13 weeks in vivo, the implant and surrounding bone tissue was harvested and microCT scanned to visualize and quantify neo-tissue formation in the porous space of the scaffold. Finally, the implant and local bone tissue was assessed by in vitro laboratory mechanical testing to quantify the osteointegration. The protocol consists of six component procedures: (i) scaffold design and finite element analysis to predict its biomechanical response, (ii) scaffold fabrication with FDM and SLS 3D printing, (iii) surface treatment of the scaffold with plasma immersion ion implantation (PIII) techniques, (iv) ovine mandibular implantation, (v) postoperative sheep recovery, euthanasia, and harvesting of the scaffold and surrounding host bone, microCT scanning, and (vi) in vitro laboratory mechanical tests of the harvested scaffolds. The results of microCT imagery and 3-point mechanical bend testing demonstrate that PIII-SLS-PEK is a promising biomaterial for the manufacturing of scaffold implants to enhance the bone-scaffold contact and bone ingrowth in porous scaffold implants. MicroCT images of the harvested implant and surrounding bone tissue showed encouraging new bone growth at the scaffold-bone interface and inside the porous network of the lattice structure of the SLS-PEK scaffolds.

VQ-CAD: Computer-Aided Design model generation with vector quantized diffusion

Computer-Aided Design (CAD) software remains a pivotal tool in modern engineering and manufacturing, driving the design of a diverse range of products. In this work, we introduce VQ-CAD, the first CAD generation model based on Denoising Diffusion Probabilistic Models. This model utilizes a vector quantized diffusion model, employing multiple hierarchical codebooks generated through VQ-VAE. This integration not only offers a novel perspective on CAD model generation but also achieves state-of-the-art performance in 3D CAD model creation in a fully automatic fashion. Our model is able to recognize and incorporate implicit design constraints by simply forgoing traditional data augmentation. Furthermore, by melding our approach with CLIP, we significantly simplify the existing design process, directly generate CAD command sequences from initial design concepts represented by text or sketches, capture design intentions, and ensure designs adhere to implicit constraints.

A Qualitative Exploration of Past Family Planning Counselling of Adolescent and Young Mothers

Objective: This study explores the family planning counselling that adolescents receive during pregnancy care, with the aim of identifying those factors that make counselling effective or ineffective. Methods: The study population consisted of ten adolescents who had recently given birth and ten health care providers. Adolescents were recruited using posters; providers, by email. Individual semistructured interviews were conducted and analyzed in keeping with grounded theory. Analysis consisted of open coding (identification of initial concepts), axial coding (drawing connections between repetitive and similar concepts), and selective coding (clustering of categories to identify themes). Results: The adolescent participants desired detailed information about pregnancy and motherhood, were challenged by the disruptive effects of pregnancy, and were strongly reliant on nonmedical support people. Our participants described that the adolescent-provider relationship was strengthened when providers sought to empower adolescents and to provide a balance of support and independence. Judgment and bias interfered with relationship building. Postpartum continuity with the pregnancy care provider and a positive relationship with the family physician were both highly desirable yet highly variable. In general, the adolescents found family planning counselling an awkward and intimate undertaking and preferred providers to slowly progress towards explicit counselling. The adolescents who opted not to initiate postpartum contraception still found the counselling process informative and beneficial. Conclusion: Effective family planning counselling is not information driven but rather gradual, individualized, and context focused. This article has been peer reviewed.
