Restorative materials are experiencing an extensive upgrade thanks to the use of chairside Computer-aided design/computer-assisted manufacturing (CAD/CAM) restorations. Therefore, due to the variety offered in the market, choosing the best material could be puzzling for the practitioner. The clinical outcome of the restoration is influenced mainly by the material and its handling than by the fabrication process (i.e., CAD/CAM). Information on the restorative materials performances can be difficult to gather and compare. The aim of this article is to provide an overview of chairside CAD/CAM materials, their classification, and clinically relevant aspects that enable the reader to select the most appropriate material for predictable success.

Abstract The current trends towards fully integrated digital design processes depend on the use of physical mockups. Free Form Fabrication extracts data from Computer Aided Design software and transforms them into a tangible reality. Virtual Reality (VR) provides a remarkable complement to these techniques. The system presented responds to the needs to ensure accurate data and quick prototyping by providing visualization and edition of Computer Aided Design files in a Virtual Environment. This paper expands on the use of VR to virtually prototype artifacts represented by .STL files. It describes different techniques to interact with the object in the VE. Besides manipulating the object, various methods to display the triangles generated by tessellation are detailed and ways to correct the files are illustrated.

This paper narrates the basic principle of the computer aided design for car styling and analyzes the current status of building the high-quality surfaces in the computer aided design for car styling and “the basic process model of digital car styling” .to build “the sbasic process model based on CAS digital modeling. It points out the research content and method of the car digital model and provides theoretical basis for the research of the car styling digital model. In the conventional early design of car styling, generally the revision of design schemes consumes much time and energies. Revisions have been continuously made from the initial creative idea to the later clay model before entering into the engineering design. With the rapid development of the computer technology, the digital technology has become the leading one for the car styling development. During the design process, the digital design of car styling has evolved from the rendering into the engineering design. In order to convey the styling idea that expresses in the design sketch in a rapid and accurate way, it requires a clear expression system and based on the system, the digital model is made. Otherwise, even the good modeling technology and the high-quality surfaces become useless without clearly expressing the idea. The computer aided design for car styling is advanced, but there still exist many problems. The paper aims to put forward a rapidly modeling method of high quality car surfaces based on digital modeling and explore its feasibility during the actual application, by analyzing the current status of building the high-quality surfaces in the computer aided design for car styling and the basic process of the computer aided design for car styling and discussing problems existed during the expression of the design, as well as combining other methods of the computer aided design in other fields.

KINSYN III is the latest version of a computer-aided linkage design system with features not previously described. Concentrating on the new features, this paper describes the system and includes case study photographs. The system has capabilities for either synthesizing or constructing pin- or slider-jointed planar linkages of almost any topology and for analysis of this same class of mechanisms. Emphasis is on synthesis techniques and man-computer graphical interaction. Problems in linkage synthesis and design are discussed along with KINSYN III’s interactive approach to their solution.

Fabrication of complete dentures (CDs) utilizing computer-aided design and computer-aided manufacturing (CAD/CAM) methods has attracted a lot of attention. The purpose of this paper was to summarize current knowledge about digital CDs and the relevant technology, and to present the application of the new technology in a dental geriatrics case. Initially, some of the challenges regarding digitization of the oral mucosa as a supporting surface of the CDs’ intaglio surface are listed. Next, a brief introduction of the CAD software capabilities regarding CDs is presented. The latest CAM additive and subtractive techniques for CDs are following. Subsequently, the consecutive steps for the construction of a digital CD as part of the prosthodontic treatment of a 90-year-old ambulative female patient are presented. Finally, some considerations about the digital workflow in CD manufacturing are discussed. In conclusion, the new digital technology has clear advantages; however, implementation requires careful planning. The digital workflow is applicable and versatile.

This article discusses changes in the digital product development. Advances in computing power are multiplying the capabilities of design engineers. Information technology has advanced at a tremendous pace. Developers of design systems have exploited this capability with sophisticated mathematics, and today's systems are capable of producing very complex designs in much higher definition than ever before. Advances in geometric modeling have made it possible to represent 3-D solids in minute detail. Process modeling, which began with the study of a single manufacturing process, eventually gave way to complete factory flow simulations. The recent advances in IT enabled crossing the boundaries among technology, geometry, and process modeling with integrated computer-aided engineering, computer-aided design, and process planning. Current trends have now extended process modeling throughout the integrated supply chain and the extended enterprise.

An effective teaching strategy that integrates computer aided design and programming into a course on mechanism analysis and design is presented. Mechanism analysis is enhanced when coupled with basic programming that allows students to find solutions to more complex systems than would otherwise be possible. Web-based distance learning is part of the class and students also learn how to create these kinds of materials themselves. Students can better understand the course material through an integrated computing environment. By solving mechanism design problems in C/C++, the programming skills gained in the course are widely applicable in other areas of engineering. Ch, a C/C++ interpreter, is used to incorporate programming and mechanism design because of its high-level numerical and graphical plotting capabilities, scripting capability, and a mechanism toolkit with easy and quick animation. A student project is given as an example to show how computers are integrated for effective learning. This teaching strategy has been actively used at UC Davis for several years in an undergraduate course in computer-aided mechanism design.
