Abstract:

As in many other industries, in the dental technology field, the production stages have begun to be increasingly machining. With the advances in computer technology, the cost-effective production of individual parts is provided. In recent years, the use of restorations produced with the help of computers has become widespread. The quality of restorations and the clinical success are assessed, while marginal adaptation is a fundamental determining feature.  The objective of this study is to provide information about the advantages and disadvantages of CAD-CAM and Laser synthesis systems used in the preparation of the substructure of metal ceramic restorations, the classification and the equipment that creates the materials and systems used in these systems and the marginal conformity work done with the relevant systems. Keywords: CAD-CAM, laser synthesis, marginal conformity MARGINAL ADAPTATION OF METAL-CERAMIC FIXED PARTIAL DENTURES FABRICATED BY CAD-CAM AND LASER SINTERING ABSTRACT As in many other industries, production stages are increasingly becoming automated in dental technology. Advances in computer technology now enable cost-effective production of individual pieces. Dental restorations produced with computer assistance have become more common in recent years. The marginal adaptation is the most important factor when the quality and clinical success of a restoration was evaluated. The aim of this article was to give an idea about the CAD/CAM and laser sintering technologies and systems available for dentistry today. The advantages, disadvantages, classification and equipment's of these systems and the studies about the marginal adaptation will be discussed too.
