The Use of CAD/CAM in Dentistry

2656 Words6 Pages

CAD/CAM is an abbreviation for computer aided design and computer aided manufacturing and involves the use of computer systems to assist in the creation, modification, analysis or optimism of a design. Its primary purpose is to create a faster production process as well as improve the quality of design. CAD/CAM is currently employed in many fields such as shipbuilding, aerospace, architecture, automotive and prosthetics (including maxillofacial prosthetics and dentistry). The concept of CAD/CAM in the field of dentistry is not a new one having been around the early 1970’s when the visionary, Dr Werner Mormann developed CEREC1. Since its inception CAD/CAM has been increasingly employed to aid the production of dental appliances, indeed nearly 50-58% of all indirect restorations today are, in part or entirely manufactured by a CAD/CAM system1. Due to the continued uptake of CAD/CAM in dentistry, it is predicted, that by the year 2015 a further 15% of dental appliances will be produced by this system, the application of CAD/CAM is aiding new areas of production such as partial frameworks, orthodontic appliances and custom implant abutments1.
About 15 systems have been developed and presented, although only a few practical and suitable systems have been introduced onto the dental market to date. The different systems can be roughly divided into chairside and labside technologies. Although there is only one established chairside system (Cerec, Sirona Dental Systems, Bensheim, Germany) for the dental practice, the rest of the systems were developed for use in dental laboratories2.
