  • Nowadays, digital dentistry is generally applied to prosthodontics with fabrication of inlays or any other fixed prostheses by utilizing CAD/CAM (computer-aided design/computer-aided manufacturing) technology and intraoral scanner. However, in fabricating removable prosthesis, there are some limitations for digital technology to substitute conventional casting method. Therefore, approaching removable prostheses fabrication with CAD/CAM technology would be a meaningful trial. In this case report, Kennedy class III mandibular edentulous patient who was in need of increasing the vertical dimension of occlusion was treated with removable partial denture using CAD and rapid prototyping technique. Surveying and designing the metal framework of the partial denture was performed with CAD, and sacrificial plastic pattern was fabricated with rapid prototyping technique. During the follow up period of nine months, the removable partial denture has provided satisfactory results in esthetics and function.

  • Recently computer-aided technology has been widely used in dentistry. DENTCA$^{TM}$ CAD/CAM denture system (DENTCA Inc.), one of CAD/CAM systems for fabricating complete denture, tries to collect and store all of a patient's information at the first visit. This system aims to deliver denture at the second visit through utilizing the CAD/CAM software to access the stored data for designing the 3D denture model. The 3 dimensional (3D) denture will then be fabricated with 3D printer. Many case reports have evaluated clinical application of CAD/CAM system for fabricating complete dentures. This case report is about fabricating of complete dentures using DENTCA system and conventional method in same patient. With two cases, usefulness and limitation of DENTCA system could be evaluated.

  • Currently with the continuous development of ceramic and cementation materials, CAD-CAM(Computer-aided design/Computer-aided manufacture) restorations are becoming increasingly popular in esthetic dentistry. Preparation design is influenced by the selected restorative material, the fabrication method, and the ability to bond the restoration. For long-lasting CAD/CAM inlay/onlay restoration, clinicians should understand the basic knowledge of CAD/CAM restoration's cavity design to obtain the fracture resistance and proper fitting margin. This article gives an overview of preparation guidelines for CAD/CAM inlay/onlay restorations.

  • The purpose of this study was to research about Dobby weave design using Computer-Aided Weaving System. For performing this design study, first, it was researched the characteristics of the classified woven fabrics, weaving processing, structure of Dobby loom, and Computer-Aided Dobby Weaving system theoretically. To develop Dobby woven design, Patternland Weave Simulator(U.S.A) for computer weave system was used. Among the developed Dobby woven designs by computer weaving system, mainly three of them were selected and woven into Dobby loom. To see the visual image of the fabric end-use, some of the scanned Dobby fabrics were simulated to the three-dimensional virtual images by Alias CAD system. The result of this study can be summarized as follows. Before the step of weaving Dobby fabrics on the woven design works, Computer-Aided Weaving system can be done very easily to apply the design step of Dobby woven fabrics, specially in case of the complicated woven structure. Also the usage of the simulation CAD system in visual image of the final products, ultimately can be saved cost and developed the higher value-added goods in more response to consumer demands.

  • In the past, computer-aided design / computer-aided manufacturing (CAD/CAM) technology was the closed system that users had to use the components of only one manufacturer. At present, it has changed to the open system with the flexibility to select and use the components of various manufacturers' components according to their needs. Despite the development of dental materials and prostheses manufacturing methods, denture manufacturing has followed conventional manufacturing methods for nearly 100 years. However, studies on CAD/CAM fabricated denture have been recently carried out to overcome the disadvantages of conventional denture manufacturing. Some commercialized products using milling or 3D printing have already been applied clinically. This case report confirms the possibility of CAD/CAM dentures using 3D face scan and compared them to conventionally fabricated dentures.

  • In recent years, precision machining of the dental prosthesis by computer assisted system is becoming pervasive in clinical dentistry. Prosthesis fabricating system that is designed by computer software and made by computer devices is called as a CAD/CAM (Computer-Aided Design/Computer-Aided Manufacturing) system. By the use of dental CAD/CAM system, the improvement of marginal compatibility and mechanical properties in prosthesis can be obtained more effectively, an aesthetic quality by using new materials such as zirconia can be increased. Also, the restoration process can be simple and efficient, the production time can be shortened, the process of manufacture can be standardized, and the mass production is possible. What is clear is that these benefits are theoretically possible, but the dentist or dental technician must understand the CAD/CAM basic principles and limitations for obtaining the maximum advantages of CAD/CAM system. For this reason, this article will be presented about the basic principles of CAD/CAM system and the factors of error that might occur in the CAD/CAM process based on my empirical study.

  • Dental computer-aided design (CAD) and computer-aided manufacturing (CAM) technology have rapidly progressed over the past 30 years. The technology, which can be used in the dental laboratory, the dental office and the form of production centers, has become more common in recent years. This technology is now applied to inlays, onlays, crowns, fixed partial dentures, removable partial denture frameworks, complete dentures, templates for implant installation, implant abutments, and even maxillofacial prostheses. Dentists and dental technicians, who want to use these techniques, should have certain basic knowledge about that. This article gives an overview of CAD/CAM technologies, histories and how it applies in prosthetic dentistry.
