Complete dentures are technologically simple to manufacture, but they require a large number of clinical and technological steps, which can lead to an increased risk of errors. With the development of digital technologies, subtractive and additive methods, the workflow has been significantly reduced, and the accuracy of prosthetic devices has increased significantly. These technologies use industrially produced materials with physical, chemical and mechanical properties superior to conventional materials. The main motives for adopting or rejecting a new technology are the relative advantages they offer over classical methods, and these can be represented by time savings, financial benefits, and clinical benefits. The present study aims to analyze the advantages and disadvantages of digitally fabricated full dentures.
