3D Facial Effects of a Simulated Dental Build-up

ABSTRACT Objective The purpose of this study was to evaluate the 3D‐stereophotogrammetry technique to detect differences in facial appearance after a simulated rehabilitation. Materials and Methods Eleven volunteers without tooth wear participated. A 3D‐stereophotograph was taken in five different situations: resting position, teeth in occlusion, and teeth in occlusion with a 1 mm‐, 3 mm‐ or 5 mm resin block between the first molars. Cephalometric measurements were performed on the 3D‐stereophotographs using the software program Maxilim® (Medicim NV Mechelen, Belgium). Four anatomical parameters were analyzed: (1) Subnasale–Gnathion, (2) Subnasale–Stomion, (3) Stomion–Gnathion, and (4) Masseter right–Masseter left. A paired Student's T‐test was applied to detect significant differences (p
