MAIN CONSIDERATIONS AND CURRENT TECHNOLOGICAL ADVANCES ON THE CAD / CAM SYSTEM: A BRIEF REVIEW.
Introduction: The CAD / CAM system was introduced in dentistry with the purpose of promoting the manufacture of prostheses based on a three-dimensional system of last generation. The CAD / CAM system consists of the intraoral scanner or the plaster model such as CAD, while the CAM is the milling machine. One of the main objectives of this technology is the simplification and optimization in the production of prosthetic structures, aiming at the production of structures with a high standard of quality and aesthetics, in a personalized and planned way with digital precision. Objective: to present the main benefits of the CAD / CAM system for the creation of dental prostheses, making a historical search and show its importance in contemporary dentistry. Methods: Experimental and clinical studies were included (case reports, retrospective, prospective and randomized trials) with qualitative and / or quantitative analysis. The words were included \\\\\\\"Dental Prostheses\\\\\\\" and \\\\\\\"CAD / CAM system\\\\\\\". Conclusion: Technological evolution has transformed something considered to be handcrafted in an automated, exact production with superior quality level, reducing the time of product preparation, eliminating costs of steps, extinguishing manual errors, thus allowing a better job, where To work with extremely durable materials.

This paper briefly describes the steps of production with the help of CNC technology, to show its usage and advantages in industry. It starts from an idea which is then brought to life in a 3D model designed in the CAD software. It is followed by defining all the parameters for CNC milling using the CAM software. Finally, it is brought to the machine to be milled. In the end, the result is a product that can be used and produced more quickly than if everything had to be done manually. Everything is modelled in SolidWorks, the parameters are defined for milling in SolidCAM, and a G-code got from SolidCAM is loaded using a post processor called Mach3.
CAD/CAM technologies for superior product modelling in the intelligence of designing complete product variants become more and more pertinent in future. Many design techniques to help interdisciplinary design actions in different engineering domains in addition to consequent processes have to be developed. A necessary job to achieve this aim is to permanently investigate the present state of the art, emerging trends, new approaches, in addition to industrial problems and requirements about the entire CAD/CAM area. With the aim of direct future research and development activities as close as possible to the continuously rising requirements of a worldwide market we carried out a wide-ranging national study in cooperation with one of the Germans leading CAD/CAM magazines. In this way, it became possible to reach a representative amount of users, to obtain their experience based assessments on today's most important aspects of CAD/CAM technology. The results of this examination are summarized in this paper to give system developers, engineers, and researchers and overview of the present condition as well as to serve as a direction for decision makers in the Design and Development areas in the modern manufacturing technologies.

Computer-Aided Design (CAD) is the use of computer systems (or workstations) to aid in the creation, modification, analysis, or optimization of a design. CAD software is used to increase the productivity of the designer, improve the quality of design, improve communications through documentation, and to create a database for manufacturing. CAD output is often in the form of electronic files for print, machining, or other manufacturing operations. The term CADD (for Computer Aided Design and Drafting) is also used. CAD may be used to design curves and figures in two-dimensional (2D) space; or curves, surfaces, and solids in three-dimensional (3D) space. CAD is an important industrial art extensively used in many applications, including automotive, shipbuilding, and aerospace industries, industrial and architectural design, prosthetics, and many more. CAD is also widely used to produce computer animation for special effects in movies, advertising and technical manuals, often called DCC digital content creation. The modern ubiquity and power of computers means that even perfume bottles and shampoo dispensers are designed using techniques unheard of by engineers of the 1960s. Because of its enormous economic importance, CAD has been a major driving force for research in computational geometry, computer graphics (both hardware and software), and discrete differential geometry.

A Comparative Study of the Accuracy of Five Cad-Cam Systems
Medicine and Pharmacy Reports, 2019
Background and aims. The study aims at comparing the precision of different CAD/CAM systems: original systems built by the same manufacturer as opposed to systems whose components are built by different manufacturers.Methods. We used the same physical cast which was scanned with five different scanners. The design of the PMMA copings was done by the same operator for the five virtual casts. Each coping was milled three times by each milling machine, thus obtaining 75 copings. The internal space was analyzed by scanning the replicas in light body silicone.Results. The results analyzed the vertical marginal space (VMS) at the preparation limit, the axial internal space (AIS) and the internal occlusal space (IOS). For VMS the best results were obtained for scanner no 5 (S5) and milling machine 3 (M3). For AIS the best results were obtained with S4 and M3 combination. For IOS the best results were obtained with S45 and M3 combination.Conclusions. According to the results of the study, w...
