Influence Of Direct And Indirect Digital Data Capturing Techniques On Marginal Accuracy And Internal Fit Of Cad/Cam Fabricated Peek And Zirconia Crowns, Samira Abdel Salam, Atef Ahmed, Nasser Ali
Al-Azhar Journal of Dentistry
Purpose: The aim of this study was to evaluate the marginal and internal fitness of PEEK and Zirconia crowns fabricated by three different impression techniques. Materials and methods: Thirty standardized acrylic die models were prepared. Dies were divided into two main groups (n= 15): Group 1: CAD/CAM fabricated zirconia crowns. Group 2: CAD/CAM fabricated PEEK crowns. Each group was subdivided into three subgroups (n= 5), according to the impression technique using for data acquisition: Sub-group (A): direct digital scans of the model used intraoral digital scanner. Sub-group (B): indirect digital scans of the silicon impressions using extraoral scanner. Sub-group (C): …
