Effect of the Association Between the Tray and Impression Techniques on Angulated Implants Using the All-on-Four System

Figure 1. Metallic aluminum matrix in AutoCAD. Figure 2. Set tray/matrix. Figure 3. Metal stock tray child after impression with addition polymerization silicone (3M ESPE Express). A condensed silicone matrix was fabricated to fill the impressions with dental stone, standardizing the format of the casts and the amount of dental stone employed. Figure 4. Plaster cast produced with matrix in AutoCAD. Figure 5. Plaster cast produced with metal stock tray. Figure 6. Image showing the framework in position on the plaster cast. Figure 7.
