Background and Aim: The design and manufacture of dental restorations with the help of milling machines has developed at a high speed since their introduction and offers more precision and options. The paradigm shift from traditional techniques to CAD/CAM technology has created a revolutionary change in the methods for fabrication of restorations. Modern milling machines dedicated to dental care are kinematic structures that work in 4 or 5 axis and represent one of the key parts of CAD/CAM. 4-axis and 5-axis machines are guided by the feed angle control and the direction of the milling cutter, which depends on the contact surface between the cutting tool and the block being turned, enabling a higher quality of surface integrity. The purpose of this review article is to investigate the types and applications of milling machines in dentistry.
Material and Method: This review study was conducted using the electronic version of articles available in the search engines PubMed and Google Scholar from 2000 to the end of 2024 using the keywords milling machine, CAD/CAM, 5-axis milling machine, 4-axis milling machine. All articles were in English and finally 32 articles were selected and reviewed.
Conclusion: Milling machines are available both for dental offices and general dental laboratories and for industrial dental laboratories. These machines increase the precision and quality of dental restorations. Restorations prepared by milling machines provide better results than conventional methods in terms of mechanical strength in chewing and aesthetics.
