The development of a 3D colour reproduction system of digital impressions with an intraoral scanner and a 3D printer: a preliminary study
Abstract This study aimed to develop a three-dimensional (3D) colour reproduction system to improve the aesthetic effects of dental prostheses. The system’s colour accuracy was also evaluated. Based on the concept of colour management, 96 colour patches were selected to develop colour profiles for a...

The 3D colour reproduction system with the best-performing (i.e. third-order polynomial regression) colour profiles was finally evaluated using tooth and gum shades.

In terms of tooth and gum shade, the median Δ$${E}_{ab}^{\ast }$$ Eab⁎ was 6.313, and half of the shade blocks were above the mismatch threshold (Δ$${E}_{ab}^{\ast }$$ Eab⁎ > 6.80). In conclusion, the colour management based on polynomial regression can decrease the colour difference of the 3D colour reproduction system, but not to clinically acceptable levels.
