control
conventionally manufactured Polymethyl Methacrylate (PMMA) mandibular implant overdentures
(DLP)-printed photo-polymerizable PMMA Nextdent mandibular implant overdenture
The bite registration records with their corresponding master casts were digitalized using an extra oral desktop 3D scanner (3shape D850) and then stored as standard triangulation language (STL) files (Figure 1). The STL files were then imported to Dental system PREMIUM3 design software (3Shape Dental System 2018) for model analysis, surveying and blocking out, designing full permanent denture bases, and for virtual teeth set-up following the recorded inter-arch space
