Abstract Digital imprint and computer-aided design/computer-aided manufacture (CAD/CAM) systems offer several benefits compared to traditional techniques. The use of a CAD/CAM system to scan preparations and generate restorations in-office, removes a second appointment for the patient. The existence of precision benefits in using complete systems and chairside scanning systems, has been proven. CAD/CAM restorations have a good longevity and meet the accepted clinical parameters. New digital impression methods are presently accessible, and before long, the long-awaited goal of sparing patients of one the most unpleasant practices in clinical dentistry, acquiring dental impressions, will be exchanged by intraoral digital scanning. CAD/CAM systems existing nowadays, can feed data through accurate digital scans created from plaster models, straight to manufacturing systems that can shape ceramic or resin restorations with no requirement of a physical copy of the prepared, adjacent, and antagonist teeth.

Continuously evolving technologies make dentistry one of the most advanced sectors in the field of medicine. The digital improvements in recent years have brought many advantages to clinicians and patients, including reduced working times, lower costs and increased efficiency of performance. Some of the most important digital technologies introduced in the dental filed are cone beam computer tomography (CBCT) scan, Computer Aided Design/Computer Aided Manufacturing (CAD-CAM) systems, and intraoral scanners. All of these allow faster and more accurate rehabilitations, with the opportunity of pre-simulation of the final treatment. The evolution of computer science has brought significant advantages in the medical and dental fields, making the diagnosis and execution of even complex treatments, such as implantology and bone reconstruction, possible. The digital world is trying to supplant the traditional analog workflow, and over time, with the further advance of technologies, it should tend to be the treatment of choice of our patients.

The article represents the information that in the age of digital dentistry, virtual treatment planning is becoming an increasingly important element of dental practice. With new technological advances in computer-aided design and computer-aided manufacturing (CAD/CAM) of dental restorations, predictable interdisciplinary treatment using a reverse planning approach appears to be beneficial and feasible. It is noted that thanks to achievements in medical imaging and computer programming, 2D axial images can be processed into other reformatted representations (sagittal and coronal) and three-dimensional (3D) virtual models representing the patient’s anatomy. It is shown that telemedicine occupies a special place among modern technologies in dentistry, which is used both for remote consultation and for the successful treatment of patients.

Implant based dental restorations have many advantages over standard removable dentures because using implants can prevent the loss of jawbones, help restore facial features, and enable the patients to get firm bites. A critical step in this kind of restorations is the fabrication of the dental bar on which the denture sits. A dental bar is patient-specific because each patient’s jawbone is unique and the device needs to be conforming to the patient’s gingival surface. The design of a dental bar is crucial to the success of dental restorations. Traditionally, designing a dental bar is a lengthy and laborious process and requires high levels of craftsmanship. There have been attempts to develop CAD/CAM systems towards automating design and fabrication of dental restorations. However, currently available commercial CAD/CAM systems are only capable of making crowns, bridges, copings, onlays and veneers, and they are not capable of making dental restorations involving multiple teeth. The present paper describes a method for computer aided design of a dental bar used in implant based dental restorations. The method starts with a set of digital scan data representing the patient’s gingival surface and generates a CAD model of a dental bar that is ready for fabrication of a physical dental bar.

CAD/CAM technology (Computer Aided Design / Computer Aided Manufacturing) in the matter of fact helps in design and development of two-dimensional or three-dimensional models and their realization on numerical controlled machines. The key to direct or indirect CAD/CAM dental restorations is the measurement of dental preparation in the mouth or on the plaster die. The aim of this paper is to describe the possibilities and the way of function of different computer aided inspection (CAI) systems as a first part of CAD/CAM systems. Different researchers have presented several approaches of methods for three dimensional (3D) measurement. Today, for chairside dental treatment, only the optical method of measurement has lead to satisfactory results in practice. Laboratory CAD/CAM systems use mechanical and optical technologies for 3D measurement. Optical impression grows as a leader of CAI segment of almost every new CAD/CAM system. The most important properties of 3D scanners are: accuracy, volume and speed of measurement and ergonomy of instrument. .

In the shipbuilding industry, it is relatively common knowledge that CAD/CAM (Computer Aided Design/ Computer Aided Manufacturing) systems can generate accurate and consistent drawings. These drawings can then be used for production support lofting, parts generation, reference material and so forth. However, one of the most significant advantages of utilizing a CAD/CAM system is not so commonly known: the development of a design database. While conventional computer systems generate, store and analyze numerical or textual databases or both, CAD/CAM systems generate, store and analyze data bases of graphics. This paper illustrates methods which optimize use of a graphic data base, focusing on the application of CAD/CAM analytical capabilities to mass properties analyses (as practiced in naval ship design). These methods are results of combining CAD/CAM technology with existing systems and knowledge to achieve cost-effective, technically superior, more accurate methods of performing engineering tasks. Accordingly, methodology, actual productivity comparisons and other related applications are presented.

ABSTRACT Computer aided design / computer aided manufacturing (CAD/CAM) systems are among the most technological advanced techniques in oral rehab today. Compared with conventional techniques, they can optimize the resistance and the adaptation of dental ceramics. Thus, their indications of use have been widened, making the technique more and more well-known and widespread. Therefore, the aim of this study is to present a literature review on comparative studies of the mechanical properties of ceramic systems produced by CAD / CAM. A search for scientific articles published between 2009 and 2019, in English, Spanish or Portuguese, was performed through the databases SCIELO, BIREME and PUBMED, using the descriptors “Ceramics”, “Computer Aided Design” and “ Partial Fixed Prosthesis “. Currently, all ceramic systems appear to have adequate strength for simple rehabilitations, but ceramic restorations produced by CAD/CAM systems present greater reliability than other manufacturing methods, presenting a wider array of indications due to their higher mechanical resistance. These systems, besides their versatility, also present an excellent aesthetic result, guaranteeing appropriate optical properties such as translucency and fluorescence, similar to natural teeth. Although the cost is a limiting factor, CAD/CAM technology is in full development and with high success rates that qualifies it as the state of art in oral rehabilitation.
