Comparison between CAD-CAM and conventional techniques in the manufacture of fixed zirconia prostheses

The use of CAD-CAM technology represents an advanced alternative to optimizing the production of fixed zirconia dental prostheses. This study focused on making a comparison between CAD-CAM techniques and conventional techniques for the production of these prostheses, evaluating various aspects. A methodology was used that combined a literature review based on high-impact academic databases and qualitative interviews with experts in the field. The findings revealed that both CAD-CAM and conventional techniques can achieve aesthetically satisfactory results in the manufacture of zirconia prostheses, depending on the experience and skill of the dental professional. No substantial differences were found to suggest that one technique alters the properties of zirconia significantly compared to the other. However, it was highlighted that CAD-CAM manufacturing systems offer advantages in terms of high quality and precision in fixed dental restorations. The choice between using one or another technology should be based on a detailed evaluation of the specific needs of the patient, considering the expertise of the dentist and the desired quality of the final result. This integrative approach ensures that the best technological option is considered based on the clinical context and patient expectations
