Color translation from monoscopic photogrammetry +ID Methodology into a Polyjet final 3D printed facial prosthesis

Area of Science:

• Biomaterials Science
• Digital Dentistry
• Prosthodontics

Background:

• Fabrication of facial prostheses traditionally relies on highly skilled artisans, limiting reproducibility.
• Digital technologies are increasingly integrated into prosthodontic workflows, enhancing outcomes.
• Combining analog and digital techniques offers novel solutions in maxillofacial prosthetics.

Purpose of the Study:

• To present an innovative digital workflow for producing a colored 3D printed facial prosthesis.
• To utilize UV-map color translation for direct colored resin 3D printing.
• To evaluate the feasibility of a digital workflow without traditional manual techniques.

Main Methods:

• A modified +ID Methodology was employed to generate 3D models.
• Calibrated 3D printable patient skin color data was obtained.
• Direct resin 3D printing was used, avoiding physical molding, manual sculpting, or intrinsic silicone coloration.

Main Results:

• The 3D printed facial prosthesis achieved acceptable aesthetics and adaptation.
• An approximate color match was obtained after extrinsic coloration.
• The patient reported good comfort and acceptance of the prosthesis.

Conclusions:

• Direct resin 3D printed facial prostheses represent a viable alternative in prosthodontics.
• This digital workflow facilitates rapid delivery, suitable for immediate prostheses.
• It provides an option for patients when experienced anaplastologists are unavailable.
