Chairside 3D digital design and trial restoration workflow
This article presents a new 3D digital smile design app for esthetic planning, smile simulation, chairside 3D virtual wax pattern, and trial restoration performed with portable devices. In this technique description, a facial frontal photograph, a facial scan standard tessellation language (STL) file, and a maxillary intraoral scan STL file were uploaded to the app. The files were calibrated to each other to allow a 3D facially driven smile design project. The definitive maxillary 3D digital waxing of facial templates was exported to a 3D printer as an STL file. The printed resin templates were directly placed in the mouth...

Tissue surface adaptation of CAD-CAM maxillary and mandibular complete denture bases manufactured by digital light processing: A clinical study
ConclusionsThe DLP and MIL denture bases demonstrated clinically acceptable tissue surface adaptation to both edentulous the maxilla and mandible. The DLP denture base was likely to exhibit intimate tissue adaptation in the stress-bearing areas of maxillary arches compared with the PAP denture base. The maxillary MIL denture base was likely to exhibit small gaps between the supporting tissue and denture base. Both DLP and MIL mandibular denture bases were likely to show intimate adaptation on the lingual slope compared with the PAP base. (Source: Dental Technology Blog)
