VILARRUBI, Alejandra; PEBE, Pablo  y  RODRIGUEZ, Andrés. Prótesis fija convencional libre de metal: tecnología CAD CAM-Zirconia, descripción de un caso clínico. Odontoestomatología [online]. 2011, vol.13, n.18, pp.16-28. ISSN 1688-9339.

There is a growing interest in the performance of crowns and fixed partial dentures based in all ceramic structures, supported by tooth or dental implants. In addition to this, there have been multiple attempts to use all ceramic FPD (fi xed partial dentures), although most of them have not achieved the expected results. From this and the aspirations of looking for a material which can combine adecuate characteristics of mechanical, aesthetic and biocompatibility properties, zirconia comes as a new material with dental applications. New technological tools are available by which clinicians can achieve more satisfactory results. The use of zirconia and CAD CAM technology in fixed partial dentures must be based on a correct diagnosis and case selection. What is more, the proper validation of: teeth preparation, impressions, framework check and cementation are essential to the fi nal success of the restoration. The purpose of this article is to describe the clinical and lab stages which involves making a zirconia fixed partial denture, by describing a clinical report

Palabras clave : zirconia; all-ceramic fixed dental prosthesis; computer-aided design/computer-aided manufacturing (CAD-CAM).
