A facially driven complete-mouth rehabilitation with ultrathin CAD-CAM composite resin veneers for a patient with severe tooth wear: A minimally invasive approach

2D and 3D patient's representation of simulated restorative esthetic outcomes using different computer‐aided design software programs

“…6,10 Different protocols have been described to elaborate a facially driven diagnostic waxing depending on the file information format obtained namely 2D photographs or 3D facial scans using 3D dental CAD software programs (Table 2). 11,12,[14][15][16][17][18][32][33][34][35][36][37][38] F I G U R E 3 Diagnostic waxing simulation using a 2D dental CAD software program (Smile Design; 3Shape)…”

“…12,[14][15][16][17][18]32,[34][35][36][37][38] Similar to 2D CAD programs, facial feature analysis is guided by vertical and horizontal line references, tooth shape and proportion guides, and a photorealistic simulation of the diagnostic waxing outcome on the 2D patient's photograph. 12,[14][15][16][17][18]32,[34][35][36][37][38] However, as an advantage compared with the 2D CAD programs, the 3D dentition is used to elaborate the diagnostic waxing procedure which can be translated to the diagnostic trial restoration in the patient's mouth by additively manufacturing (AM) the diagnostic waxing cast, 34,35 milling the diagnostic trial restoration, 32 or AM the silicone index designed from the digital diagnostic waxing cast. 12,[14][15][16][35][36][37] A previous study compared patient satisfaction between the digitally designed pre-visualization simulation on the participant's photograph and the direct evaluation of the milled diagnostic trial restoration in 28 participants.…”

“…3D dental CAD software programs allow a superimposition procedure to merge the 3D dentition with the 2D facial photographs using an iterative closest point (ICP) algorithm (Figure 4). 12,14‐18,32,34‐38 Similar to 2D CAD programs, facial feature analysis is guided by vertical and horizontal line references, tooth shape and proportion guides, and a photorealistic simulation of the diagnostic waxing outcome on the 2D patient's photograph 12,14‐18,32,34‐38 . However, as an advantage compared with the 2D CAD programs, the 3D dentition is used to elaborate the diagnostic waxing procedure which can be translated to the diagnostic trial restoration in the patient's mouth by additively manufacturing (AM) the diagnostic waxing cast, 34,35 milling the diagnostic trial restoration, 32 or AM the silicone index designed from the digital diagnostic waxing cast 12,14‐16,35‐37 …”

“…The digital diagnostic waxing was used to design and additively manufacture 3‐piece 16,37 or 4‐piece 36 silicone indices which aided transferring the diagnostic waxing into the patient's mouth 16,36,37 . After, the same technique has been described to treatment plan a complete‐mouth rehabilitation accomplished with ultrathin CAD‐CAM composite resin veneers for a patient with severe tooth wear 38 …”

Dental software classification and dento‐facial interdisciplinary planning platform

“…The complete digital workflow has been widely studied and reported in several areas of dentistry 1‐13 . Recently, a conceptual digital workflow that changes and improves the process of treating a comprehensive case from planning to execution has been presented with six key steps (Figure 1).…”
