Computer-Aided Design and Computer-Aided Manufacturing systems, tailored for dentistry, represent a technological approach to designing and creating dental restorations, prosthetics, and appliances. This technology allows dental professionals to digitally design a restoration, such as a crown or bridge, and then manufacture it using computer-controlled milling machines or 3D printers. For example, a dentist can scan a patient’s prepared tooth, design a custom crown using specialized programs, and then fabricate the crown in-office within a single appointment.
These digital workflows offer several advantages over traditional methods, including increased precision, faster turnaround times, and the ability to create more complex designs. Historically, dental restorations were fabricated manually by dental technicians, a process that could be time-consuming and subject to human error. The introduction of digital technologies has revolutionized the field, improving the quality and efficiency of dental care and patient satisfaction.
The remainder of this article will explore the specific components of these systems, including intraoral scanners, design programs, and manufacturing units. Furthermore, it will examine the various applications within restorative dentistry, orthodontics, and implantology, and consider the current challenges and future trends shaping the field.
